Dear Jaypep, or whoever the hell u are ... I suggest you spend some time reading on the history of OSM and what it serves. Its far more than a "travel app".  If people like u dont understand the correct protocol for tagging, then I suggest you refrain from editing the map.  Building numbers are very important especially for routing, and thats why they are put in the map using the addr:housenumber tag.  Please take the time to read the Wiki on this.  
I have been been mapping for 7 years with over 4,000 edits to my credit ... it seems like you have just started out with 163.... so please take this in the spirit I have written it and try to understand that Maps.me uses data from OSM that many others have contributed to. Rgds, Russ,
