What kind of abode doesn't have a mailing address for USPS? I don't really get that  

I live in an apartment complex and we have a central mailbox thing (by the apartment office ) and each apartment has a tiny little mailbox and we get a key for it and it all goes it there  

Yes, I just used the word abode
