House numbers are not numbers in plenty of cases. Youy'll probably want to account at least somewhat for international addresses too, since most companies end up dealing with them sooner or later, if only to tell the customer you won't ship there. I run into this sort of thing somewhat frequently. A multinational food delivery company here had a period for a couple years where it'd parse "1st whateverstreet 123" as an address on whateverstreer with the number "1st", dropping the 123 entirely. This may seem a bit silly but keep in mind that over here "123 Annex B" is a valid house number for instance, which might be a different building from "123B".
