(1) This Registration Statement also covers an indeterminable number of
    additional shares that may be issued as a result of an adjustment in the
    shares in the event of a stock split, stock dividend or similar capital
    adjustment, as required by the Plan.

(2) The price stated is estimated solely for purposes of calculation of the
    registration fee and is the average of the sum of (i) the aggregate
    exercise price of options for 15,475 shares previously granted under the
    Plans and (ii) the product resulting from multiplying the remaining
    374,527 shares by $.12, the closing price of shares of the Common Stock
    on the OTC Bulletin Board on July 8, 2002.

(3) Pursuant to Rule 457(p), $8.40 is being offset against the total filing
    fee due for this registration statement, which is $8.40.  That amount
    represents a portion of the filing fee paid by Ultradata Systems,
    Incorporated upon filing, on June 16, 2000, of a Registration Statement
    on Form SB-2 (File No. 333-39434).  Of the 2,699,502 shares registered in
    that filing, 2,633,814 remained unsold when the offering was terminated.
    Accordingly, $2,107.87 of the $2,160.45 paid with that filing remained
    available to be offset against future filing fees.  Of that sum, $407.10
    was applied to the filing fee for the Registrant's Registration Statement
    on Form SB-2 (File No. 333-39434), but that Registration Statement was
    subsequently withdrawn without any securities being sold.  Accordingly,
    the full $2,107.87 remains available to be offset against the filing fee
    due for this registration statement.

Item 3.  Incorporation of Documents by Reference.

	 Ultradata Systems, Incorporated is incorporating by reference the

	 Ultradata is also incorporating by reference all documents hereafter
filed by Ultradata pursuant to Sections 13(a), 13(c), 14 and 15(d) of the
Securities Exchange Act of 1934, prior to the filing of a post-effective
amendment which indicates that all securities offered have been sold or which

Item 4.  Description of Securities.

	 Not Applicable.

Item 5.  Interests of Named Experts and Counsel.

	 Robert Brantl, Esq., counsel to Ultradata, has passed upon the
validity of the shares registered pursuant to this Registration Statement.
Mr. Brantl owns 22,000 shares of Ultradata common stock.

Item 6.  Indemnification of Directors and Officers.

	 Section 145 of the General Corporation Law of the State of Delaware
authorizes a corporation to provide indemnification to a director, officer,
employee or agent of the corporation, including attorneys' fees, judgments,
fines and amounts paid in settlement, actually and reasonably incurred by him
in connection with such action, suit or proceeding, if such party acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful as determined in accordance with the statute, and except that with
respect to any action which results in a judgment against the person and in
favor of the corporation the corporation may not indemnify unless a court
determines that the person is fairly and reasonably entitled to the
indemnification. Section 145 further provides that indemnification shall be
provided if the party in question is successful on the merits.

Item 7.  Exemption from Registration Claimed.

	 Not applicable.

Item 8.  Exhibits.

	 4.1   1994 Incentive Stock Option Plan - filed as an exhibit to

	 5     Opinion of Robert Brantl, Esq.

	 23.1  Consent of Weinberg & Company, P.A., certified public
accountants

	 23.2  Consent of Robert Brantl, Esq. is contained in his opinion,
filed as Exhibit 5.

Item 9.  Undertakings.

	 Ultradata hereby undertakes:

	 (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include
any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to
such information in the Registration Statement;

	 (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof;

	 (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering;

	 (4) That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

	 Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of Ultradata pursuant to the provisions of the General Corporation
Law of the State of Delaware, or otherwise, Ultradata has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by Ultradata of expenses incurred or paid
by a director, officer or controlling person of Ultradata in the successful
defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being
registered, Ultradata will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.

			      RISK FACTORS

	 You should carefully consider the risks described below before buying
our common stock.  If any of the risks described below actually occurs, that
event could cause the trading price of our common stock to decline, and you
could lose all or part of your investment.

	 We may not become profitable.

	 During 1998, 1999, 2000 and 2001 combined, we lost over $9.3 million.
Our working capital was reduced from $10 million to less than $2 million.  In
the first quarter of this year, we lost an additional $128,028.  Unless our
sales increase significantly, we will continue to sustain losses.

	 If the products that we are introducing in 2002 are not successful,
the future viability of our business will be in doubt.

	 In the past three years, our sales have fallen sharply, we have
significantly reduced our working capital, and the price of our common stock
is less than five percent of its price three years ago.  Many people, both
inside our company and in the investment community, consider our entry into
the GPS market (through Travel*Star 24) as the test of our ability to develop
and grow as a company.  If we fail to capitalize on that opportunity in 2002,
whether due to poor planning or factors beyond our control, the failure will
likely prevent us from obtaining additional capital.

	 Our sales are highly seasonal, which limits our growth.

	 Retailers continue to categorize our Road Whiz products in the "gifts"
niche.  As a result, we realize the majority of our sales in the fourth
quarter, attributable to holiday shopping.  During 2001, we realized over 50%
of our sales in the fourth quarter.  We expect similar seasonality during
2002.  The seasonality of our sales will be alleviated only if we can
convince retailers to market our Road Whiz products throughout the year or
if our new products develop significant year-round sales.  This seasonality
limits our growth.  It also makes our company unattractive to investors, due
to the fact that we can show positive financial results for only one quarter
each year.

	 Our borrowing capacity is limited, which makes it difficult for us to
finance our orders.

	 Our ability to finance the manufacturing needed to fill purchase
orders depends on our ability to borrow money, secured by our working capital.
In July 2001, our primary lender did  not renew our $1 million credit line.
If we are unable to obtain credit in the future, it could prevent us from
filling large orders, which would have a serious negative effect on our
marketing relationships.

	 Our primary marketing strategy is to sell our products to mass market
retailers.  This makes us dependent on a small group of large customers for
most of our sales.

	 Our decision in 1998 to focus our marketing efforts on mass market
retailers has increased the percentage of our revenues attributable to large
customers.  In 2000 two new customers accounted for 72.4% of our sales and
four customers (including only one of the four largest in 1999) accounted for
almost 90% of our sales.  In 2001 three customers accounted for over 69% of
our sales.  We expect a similar pattern in 2002 and thereafter. Our dependence
on major customers means that the loss of business from one or more major
customers could adversely affect our financial results.

	 Several large marketing enterprises have become involved in the GPS
market.  We will attempt to compete in this market with relatively meager
resources, and could be defeated by the efforts of one or more of our
competitors.

	 A product that performs substantially all of the functions of
Travel*Star 24 could appear on the market tomorrow, at the price we intend to
charge for Travel*Star 24 .  Indeed, the success of Travel*Star 24, should it
occur, is likely to propel the introduction of competitive products into the
market.  If the introduction of a comparable product were financed
aggressively, Ultradata could find itself unable to market Travel*Star 24
profitably.

	 We will require additional financing if Travel*Star 24 is successful,
in order to fund new orders.

	 If the introduction of Travel*Star 24 leads to a large demand for
that product, we may need additional funds to pay the costs of manufacturing
inventory.   We will then have to either sell additional equity or finance
the orders by some other means.  If we are unable to secure the necessary
financing, our efforts to establish Travel*Star 24 in the GPS market could be
severely hampered.

	 We have limited experience in the automotive after-market.  Our lack
of experience may cause us to underestimate the challenges facing us in those
markets.

	 Our plan is to improve our financial performance by expanding our
operations into new markets.  This strategy carries the risk of the unknown.
Many of our present customers could become customers for Travel*Star 24.
However, we expect to also distribute Travel*Star 24 through marketing
channels, such as auto parts dealers, with which we have limited experience.
We may not anticipate circumstances involving competition, marketing strategy,
regulation, or technology that prove harmful to our program for growth.

	 Our future could be adversely affected, if we lost the services of our
Chief Executive Officer.

	 Monte Ross has been the primary architect of our business strategy
and marketing program.  If his services were not available to us, Ultradata
would likely be adversely affected until a replacement could be found.  We
have an employment agreement with Mr. Ross, the term of which expires on
October 1, 2003.  The agreement provides that Mr. Ross may not compete with
Ultradata for one year after termination of his employment.

	 There is no market maker providing strong support for our common
stock.  As a result, the common stock is low-priced, thinly traded, and
subject to relatively wide swings in price.

	 For most of the past three years, with the decline in the Ultradata's
business results, interest in our common stock within the investment community
has waned.  This situation was exacerbated in 2001, when our common stock was
removed from Nasdaq to the OTC Bulletin Board. Many brokerage firms will not
recommend a security that is quoted only on the OTC Bulletin Board, which
further limits interest in our common stock.  Unless interest in the common
stock is sustained and a thriving market for the common stock reemerges, you
may find it impossible to sell Ultradata shares at a profit, and may find it
difficult to sell them at all.

	 The Convertible Notes may be converted into large numbers of shares
of common stock, which would dilute the value of your shares.

	 Ultradata has issued Convertible Promissory Notes with a face value
of $654,913.  Ultradata pays a portion of that debt each month.  However,
until Ultradata pays down the Notes in full, the principal and interest on the
Notes may be converted into common stock.  The conversion price is 70% of the
average closing bid price for the five days preceding the conversion.  If the
average were $.126 (as it was on July 10, 2002), the principal amount of the
Notes would be convertible into 7,425,317 shares of common stock, which would
represent 69% of the outstanding shares.  This conversion cannot happen all at
once, as the Notes cannot be converted during any 90 day period into more than
28% of the trading volume for the common stock during the preceding 66 trading
days.  But, over time, conversion of the Notes could theoretically convert
into 99% of the outstanding common shares, which would render your shares
virtually worthless.

			   INDEMNIFICATION


	 Our certificate of incorporation provides that our directors shall be
indemnified by us to the extent authorized by Delaware law.   Section 145 of
the General Corporation Law of the State of Delaware authorizes a corporation
to provide indemnification to a director, officer, employee or agent of the
corporation, including attorneys' fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such
action, suit or proceeding, under certain circumstances.  The requisite
circumstances are that the party seeking indemnification acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful as
determined in accordance with the statute.  However, with respect to any
action which results in a judgment against the person and in favor of the
corporation, the corporation may not indemnify unless a court determines that
the person is fairly and reasonably entitled to the indemnification. Section
145 further provides that indemnification shall be provided if the party in
question is successful on the merits.

	 Insofar as indemnification for liabilities under the Securities Act
of 1933 may be permitted to our directors, officers or controlling persons
pursuant to the foregoing provision or otherwise, we have been advised that
in the opinion of the SEC such indemnification is against public policy as
expressed in that Act and is, therefore, unenforceable.

(1) This Registration Statement also covers an indeterminable number of
    additional shares that may be issued as a result of an adjustment in the
    shares in the event of a stock split, stock dividend or similar capital
    adjustment, as required by the Plan.

(2) The price stated is estimated solely for purposes of calculation of the
    registration fee and is the average of the sum of (i) the aggregate
    exercise price of options for 15,475 shares previously granted under the
    Plans and (ii) the product resulting from multiplying the remaining
    374,527 shares by $.12, the closing price of shares of the Common Stock
    on the OTC Bulletin Board on July 8, 2002.

(3) Pursuant to Rule 457(p), $8.40 is being offset against the total filing
    fee due for this registration statement, which is $8.40.  That amount
    represents a portion of the filing fee paid by Ultradata Systems,
    Incorporated upon filing, on June 16, 2000, of a Registration Statement
    on Form SB-2 (File No. 333-39434).  Of the 2,699,502 shares registered in
    that filing, 2,633,814 remained unsold when the offering was terminated.
    Accordingly, $2,107.87 of the $2,160.45 paid with that filing remained
    available to be offset against future filing fees.  Of that sum, $407.10
    was applied to the filing fee for the Registrant's Registration Statement
    on Form SB-2 (File No. 333-39434), but that Registration Statement was
    subsequently withdrawn without any securities being sold.  Accordingly,
    the full $2,107.87 remains available to be offset against the filing fee
    due for this registration statement.

Item 6.  Indemnification of Directors and Officers.

	 Section 145 of the General Corporation Law of the State of Delaware
authorizes a corporation to provide indemnification to a director, officer,
employee or agent of the corporation, including attorneys' fees, judgments,

in connection with such action, suit or proceeding, if such party acted in
good faith and in a manner he reasonably believed to be in or not opposed to

action or proceeding, had no reasonable cause to believe his conduct was
unlawful as determined in accordance with the statute, and except that with
respect to any action which results in a judgment against the person and in
favor of the corporation the corporation may not indemnify unless a court
determines that the person is fairly and reasonably entitled to the
indemnification. Section 145 further provides that indemnification shall be
provided if the party in question is successful on the merits.

	 23.2  Consent of Robert Brantl, Esq. is contained in his opinion,

Item 9.  Undertakings.

	 Ultradata hereby undertakes:

	 (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include
any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to
such information in the Registration Statement;

	 (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof;

	 (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering;

	 (4) That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

	 Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of Ultradata pursuant to the provisions of the General Corporation
Law of the State of Delaware, or otherwise, Ultradata has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by Ultradata of expenses incurred or paid
by a director, officer or controlling person of Ultradata in the successful
defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being
registered, Ultradata will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.

			      RISK FACTORS

	 You should carefully consider the risks described below before buying
our common stock.  If any of the risks described below actually occurs, that
event could cause the trading price of our common stock to decline, and you
could lose all or part of your investment.

	 We may not become profitable.

	 During 1998, 1999, 2000 and 2001 combined, we lost over $9.3 million.
Our working capital was reduced from $10 million to less than $2 million.  In
the first quarter of this year, we lost an additional $128,028.  Unless our
sales increase significantly, we will continue to sustain losses.

	 If the products that we are introducing in 2002 are not successful,
the future viability of our business will be in doubt.

	 In the past three years, our sales have fallen sharply, we have
significantly reduced our working capital, and the price of our common stock
is less than five percent of its price three years ago.  Many people, both
inside our company and in the investment community, consider our entry into
the GPS market (through Travel*Star 24) as the test of our ability to develop
and grow as a company.  If we fail to capitalize on that opportunity in 2002,
whether due to poor planning or factors beyond our control, the failure will
likely prevent us from obtaining additional capital.

	 Our sales are highly seasonal, which limits our growth.

	 Retailers continue to categorize our Road Whiz products in the "gifts"
niche.  As a result, we realize the majority of our sales in the fourth
quarter, attributable to holiday shopping.  During 2001, we realized over 50%
of our sales in the fourth quarter.  We expect similar seasonality during
2002.  The seasonality of our sales will be alleviated only if we can
convince retailers to market our Road Whiz products throughout the year or
if our new products develop significant year-round sales.  This seasonality
limits our growth.  It also makes our company unattractive to investors, due
to the fact that we can show positive financial results for only one quarter
each year.

	 Our borrowing capacity is limited, which makes it difficult for us to
finance our orders.

	 Our ability to finance the manufacturing needed to fill purchase
orders depends on our ability to borrow money, secured by our working capital.
In July 2001, our primary lender did  not renew our $1 million credit line.
If we are unable to obtain credit in the future, it could prevent us from
filling large orders, which would have a serious negative effect on our
marketing relationships.

	 Our primary marketing strategy is to sell our products to mass market
retailers.  This makes us dependent on a small group of large customers for
most of our sales.

	 Our decision in 1998 to focus our marketing efforts on mass market
retailers has increased the percentage of our revenues attributable to large
customers.  In 2000 two new customers accounted for 72.4% of our sales and
four customers (including only one of the four largest in 1999) accounted for
almost 90% of our sales.  In 2001 three customers accounted for over 69% of
our sales.  We expect a similar pattern in 2002 and thereafter. Our dependence
on major customers means that the loss of business from one or more major
customers could adversely affect our financial results.

	 Several large marketing enterprises have become involved in the GPS
market.  We will attempt to compete in this market with relatively meager
resources, and could be defeated by the efforts of one or more of our
competitors.

	 A product that performs substantially all of the functions of
Travel*Star 24 could appear on the market tomorrow, at the price we intend to
charge for Travel*Star 24 .  Indeed, the success of Travel*Star 24, should it
occur, is likely to propel the introduction of competitive products into the
market.  If the introduction of a comparable product were financed
aggressively, Ultradata could find itself unable to market Travel*Star 24
profitably.

	 We will require additional financing if Travel*Star 24 is successful,
in order to fund new orders.

	 If the introduction of Travel*Star 24 leads to a large demand for
that product, we may need additional funds to pay the costs of manufacturing
inventory.   We will then have to either sell additional equity or finance
the orders by some other means.  If we are unable to secure the necessary
financing, our efforts to establish Travel*Star 24 in the GPS market could be
severely hampered.

	 We have limited experience in the automotive after-market.  Our lack
of experience may cause us to underestimate the challenges facing us in those
markets.

	 Our plan is to improve our financial performance by expanding our
operations into new markets.  This strategy carries the risk of the unknown.
Many of our present customers could become customers for Travel*Star 24.
However, we expect to also distribute Travel*Star 24 through marketing
channels, such as auto parts dealers, with which we have limited experience.
We may not anticipate circumstances involving competition, marketing strategy,
regulation, or technology that prove harmful to our program for growth.

	 Our future could be adversely affected, if we lost the services of our
Chief Executive Officer.

	 Monte Ross has been the primary architect of our business strategy
and marketing program.  If his services were not available to us, Ultradata
would likely be adversely affected until a replacement could be found.  We
have an employment agreement with Mr. Ross, the term of which expires on
October 1, 2003.  The agreement provides that Mr. Ross may not compete with
Ultradata for one year after termination of his employment.

	 There is no market maker providing strong support for our common
stock.  As a result, the common stock is low-priced, thinly traded, and
subject to relatively wide swings in price.

	 For most of the past three years, with the decline in the Ultradata's
business results, interest in our common stock within the investment community
has waned.  This situation was exacerbated in 2001, when our common stock was
removed from Nasdaq to the OTC Bulletin Board. Many brokerage firms will not
recommend a security that is quoted only on the OTC Bulletin Board, which
further limits interest in our common stock.  Unless interest in the common
stock is sustained and a thriving market for the common stock reemerges, you
may find it impossible to sell Ultradata shares at a profit, and may find it
difficult to sell them at all.

	 The Convertible Notes may be converted into large numbers of shares
of common stock, which would dilute the value of your shares.

	 Ultradata has issued Convertible Promissory Notes with a face value
of $654,913.  Ultradata pays a portion of that debt each month.  However,
until Ultradata pays down the Notes in full, the principal and interest on the
Notes may be converted into common stock.  The conversion price is 70% of the
average closing bid price for the five days preceding the conversion.  If the
average were $.126 (as it was on July 10, 2002), the principal amount of the
Notes would be convertible into 7,425,317 shares of common stock, which would
represent 69% of the outstanding shares.  This conversion cannot happen all at
once, as the Notes cannot be converted during any 90 day period into more than
28% of the trading volume for the common stock during the preceding 66 trading
days.  But, over time, conversion of the Notes could theoretically convert
into 99% of the outstanding common shares, which would render your shares
virtually worthless.

			   INDEMNIFICATION

	 Our certificate of incorporation provides that our directors shall be
indemnified by us to the extent authorized by Delaware law.   Section 145 of
the General Corporation Law of the State of Delaware authorizes a corporation
to provide indemnification to a director, officer, employee or agent of the
corporation, including attorneys' fees, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such
action, suit or proceeding, under certain circumstances.  The requisite
circumstances are that the party seeking indemnification acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful as
determined in accordance with the statute.  However, with respect to any
action which results in a judgment against the person and in favor of the
corporation, the corporation may not indemnify unless a court determines that
the person is fairly and reasonably entitled to the indemnification. Section
145 further provides that indemnification shall be provided if the party in
question is successful on the merits.

	 Insofar as indemnification for liabilities under the Securities Act
of 1933 may be permitted to our directors, officers or controlling persons
pursuant to the foregoing provision or otherwise, we have been advised that
in the opinion of the SEC such indemnification is against public policy as
expressed in that Act and is, therefore, unenforceable.
