Are you referring to the 5 or 9 digit variant? Presumably not the 11 digit one as that corresponds to your unique address. (It follows that the 9 digit variant corresponds to at most 100 mailboxes.)
I've never tried inputting my 11 digit code in an online form but at least the 9 digit one is readily accepted. In my experience the last 4 will usually be completed for me based on the street address and if it can't find a match it gives me an error.
- HeyLaughingBoy 2y agoI didn't even know there was an 11 digit code until now! I was referring to the 5 digit code. 9 digit would be closer, but around here 100 mailboxes (zip+4 would actually be 9999 mailboxes) is still quite a few square miles. If I look out my living room window, I can see maybe 10 houses, and that's with a view that comes from living on top of a hill.
- fc417fc802 2y agoZip+4 (9 digit) can't ever be more than 100 mailboxes because 11 digit is guaranteed unique. It follows that a 5 digit zip is limited to 1M boxes. Unless I have a misunderstanding about 11 digit being unique anyway.
