For mailing addresses, yes.  For street addresses, maybe.  The Census does
have areas for their ZIP codes.  Whether a particular area uses Census or
Postal zips depends on whether or not they're served by the USPS directly
(and there's decent chunks that don't).  Edge case is super edge, though,
and the de-facto way of dealing with this is to just use the ZIP observed
on the address marker or ask someone who lives/works there what the ZIP is
