I definitely agree in principle. But - without doxxing myself - I input my zip and the city is not correct. It’s a very close neighboring suburb (where the boundaries are definitely blurry) but it’s not the city on all the legal documents for my current house.

My brother’s house is in the same boat. Unfortunately, not all ZIP codes exclusively belong to one city.

Yeah city is not fully a function of zip. ~I think state is though.~* I believe when multiple cities share a zip code USPS uses the larger one. Usually the wrong city will get delivered though, probably not guaranteed.

* correcting myself, some zip codes do cross state lines

Zip code is a very powerful factor from a PII perspective.

Legal address doesn't matter for mail, and all of this stuff is about mail/shipping. This includes billing addresses.

I would have assumed that you knew that. I know people whose ZIP code belongs to a neighboring town (because mail works that way) and it basically becomes their de-facto address.
