Item 3.  Incorporation of Documents by Reference
         ---------------------------------------

               Stamps.com Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

          (a)  The Registrant's Annual Report on Form 10-K405 for the fiscal
               year ended December 31, 2000 filed with the Commission on March
               30, 2000, as amended on Form 10-K405/A filed with the Commission
               on April 28, 2000, pursuant to Section 13 of the Securities
               Exchange Act of 1934 as amended (the "1934 Act").

          (b)  The Registrant's Quarterly Reports on Form 10-Q for the fiscal
               quarter ended March 31, 2000 filed with the Commission on May 15,
               2000;

          (c)  The Registrant's Current Reports on Form 8-K for the period ended
               March 7, 2000 filed with the Commission on March 9, 2000 and
               March 22, 2000, respectively; and

          (d)  The Corporation's Registration Statement on Form 8-A12G filed
               with the Commission on June 17, 1999, pursuant to Section 12(g)
               of the 1934 Act in which are described the terms, rights and
               provisions applicable to the Corporation's outstanding Common
               Stock.

               All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of
this Registration Statement and prior to the filing of a post-effective
amendment which indicates that all securities offered hereby have been sold or
which de-registers all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

Item 4.  Description of Securities
         --------------------------

               Not Applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------

               Not Applicable.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

               Section 145 of the Delaware law empowers a corporation to
indemnify its directors and officers and to purchase insurance with respect to
liability arising out of their capacity or status as directors and officers, but
this statutory provision does not eliminate or limit the liability of a
director:

               .  for any breach of the director's duty of loyalty to the
                  corporation or its stockholders;

               .  for acts or omissions not in good faith or which involve
                  intentional misconduct or a knowing violation of law;

                                      II-1
<PAGE>

               .  for any liability arising under Section 174 of the Delaware
                  law; or

               .  for any transaction from which the director derived an
                  improper personal benefit.

               The Delaware law provides further that the indemnification
permitted thereunder shall not be deemed exclusive of any other rights to which
the directors and officers may be entitled under the corporation's bylaws, or by
reason of any agreement, a vote of stockholders or otherwise. The Registrant's
certificate of incorporation provides that the Registrant indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding by reason of the fact that the
person is or was a director or officer, or is or was serving at the Registrant's
request as a director or officer of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, against expenses,
judgements, fines and amounts paid in settlement actually and reasonably
incurred by the person in the action, suit or proceeding.

               The Registrant has entered into indemnification agreements with
its directors and executive officers containing provisions that may require the
Registrant, among other things, to indemnify its directors and officers against
liabilities that may arise by reason of their status or service as directors or
officers other than liabilities arising from willful misconduct of a culpable
nature, to advance their expenses incurred as a result of any proceeding against
them as to which they could be indemnified, and to obtain directors' and
officers' liability insurance if maintained for other directors or officers.

Item 7.  Exemption from Registration Claimed

Item 9.  Undertakings
         ------------

               A.   The undersigned Registrant hereby undertakes: (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement: (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts
or events arising after the effective date of this Registration Statement (or
the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those clauses is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act 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; and (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 Registrant's 1999
Stock Incentive Plan.

                                      II-2
<PAGE>

               B.   The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act that is incorporated by reference into this Registration Statement
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.

               C.   Insofar as indemnification for liabilities arising under the
1933 Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the
Commission, such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant 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, the Registrant 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 1933 Act and
will be governed by the final adjudication of such issue.

Item 3.  Incorporation of Documents by Reference
         ---------------------------------------

               Stamps.com Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

          (a)  The Registrant's Annual Report on Form 10-K405 for the fiscal
               year ended December 31, 2000 filed with the Commission on March
               30, 2000, as amended on Form 10-K405/A filed with the Commission
               on April 28, 2000, pursuant to Section 13 of the Securities
               Exchange Act of 1934 as amended (the "1934 Act").

          (b)  The Registrant's Quarterly Reports on Form 10-Q for the fiscal
               quarter ended March 31, 2000 filed with the Commission on May 15,
               2000;

          (c)  The Registrant's Current Reports on Form 8-K for the period ended
               March 7, 2000 filed with the Commission on March 9, 2000 and
               March 22, 2000, respectively; and

          (d)  The Corporation's Registration Statement on Form 8-A12G filed
               with the Commission on June 17, 1999, pursuant to Section 12(g)
               of the 1934 Act in which are described the terms, rights and
               provisions applicable to the Corporation's outstanding Common
               Stock.

               All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of
this Registration Statement and prior to the filing of a post-effective
amendment which indicates that all securities offered hereby have been sold or
which de-registers all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

Item 4.  Description of Securities
         --------------------------

               Not Applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------

               Not Applicable.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

               Section 145 of the Delaware law empowers a corporation to
indemnify its directors and officers and to purchase insurance with respect to
liability arising out of their capacity or status as directors and officers, but
this statutory provision does not eliminate or limit the liability of a
director:

               .  for any breach of the director's duty of loyalty to the
                  corporation or its stockholders;

               .  for acts or omissions not in good faith or which involve
                  intentional misconduct or a knowing violation of law;

                                      II-1
.  for any liability arising under Section 174 of the Delaware
                  law; or

               .  for any transaction from which the director derived an
                  improper personal benefit.

               The Delaware law provides further that the indemnification
permitted thereunder shall not be deemed exclusive of any other rights to which
the directors and officers may be entitled under the corporation's bylaws, or by
reason of any agreement, a vote of stockholders or otherwise. The Registrant's
certificate of incorporation provides that the Registrant indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding by reason of the fact that the
person is or was a director or officer, or is or was serving at the Registrant's
request as a director or officer of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, against expenses,
judgements, fines and amounts paid in settlement actually and reasonably
incurred by the person in the action, suit or proceeding.

               The Registrant has entered into indemnification agreements with
its directors and executive officers containing provisions that may require the
Registrant, among other things, to indemnify its directors and officers against
liabilities that may arise by reason of their status or service as directors or
officers other than liabilities arising from willful misconduct of a culpable
nature, to advance their expenses incurred as a result of any proceeding against
them as to which they could be indemnified, and to obtain directors' and
officers' liability insurance if maintained for other directors or officers.

Item 9.  Undertakings
         ------------

               A.   The undersigned Registrant hereby undertakes: (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement: (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts
or events arising after the effective date of this Registration Statement (or
the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those clauses is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act 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; and (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 Registrant's 1999
Stock Incentive Plan.

                                      II-2
B.   The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act that is incorporated by reference into this Registration Statement
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.

               C.   Insofar as indemnification for liabilities arising under the
1933 Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the
Commission, such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant 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, the Registrant 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 1933 Act and
will be governed by the final adjudication of such issue.

this Registration Statement to be signed on its behalf by the undersigned,
