USA mailing addresses are strictly that -- an identifier for the convenience of the Post Office which may or may not correspond to the underlying jurisdictions for things like political boundaries, tax authorities, etc.
I learned this when setting up voter databases. A house that is in a given city/precinct/etc (the atomic identity is parcel number) may have a mailing address in a completely different city. There are many such cases for Los Gatos vs Saratoga, for example. Also, the USPS considers every address to be in some "city" even on unincorporated parcels.
Back when phone area codes and prefixes had precise geographical meanings, many edge cases ended up on the "wrong" area code (e.g. Sunnyvale numbers being in 415/650 instead of 408 between the 85 freeway and the Sunnyvale border).
