Yes, unfortunately, their assertion that everyone knows their zip code is wrong. People often write a neighboring code, and the post office just delivers it. Similar issues for city name, of course.
This sounds like the person doesn't know the receiver's zip code. Why are you extending that to not knowing their own zip code? Are they mailing something to themselves?

This is a tangent, but addresses are also way more complicated than most people realize - especially if you’re relying on a user to input a correct address or if you need to support multiple countries, somewhere with unique addresses like Queens[0], or you need to differentiate between units of a specific street address that uses something other than unit numbers for a unit designation. At that point you need somethi…
Just last week I had to deal with the fact that my house has the wrong address in multiple databases because things changed when an interstate went in 40-something years ago. It's not a big change--main st. vs N main st. but it was enough to mess up various things. Not as much as when I moved in 30 years ago but still enough to be wrong in old town and telco records. Took me a couple of days to get a permit issued to…

And in this case the fire companies had no problem finding my house in spite of the incorrect information in town records. As you suggest the field people on the ground generally know what the ground truth is.
ZIP codes are an emergent property of the mail delivery system. While the author might consider this a bad thing, this makes them "good enough" on multiple axes in practice. They tend to be: - Well-known (everybody knows their zip code) - Easily extracted (they're part of every address, no geocoding required) - Uniform-enough (not perfect, but in most cases close) - Granular-enough - Contiguous-enough by travel time…
