phone number? that's a string!
house number? that's a string!
credit card number? that's a string! and one you should try very hard to never see in the first place!
zip code? that's a string!
IP address? database ID? UUID if you're feeling spicy? can be encoded more densely in an integer-shaped format but semantically that is a goddamn string!!!
i mean usually house_number % 2 tells you which side of the street it's on, even if there's no semblance of consistently for what result is east/west or north/south, and this of course falls apart completely in apartment complexes and probably other situations i'm not thinking about. also zip codes generally get higher as you go west, but are comparisons really math
the odd/even thing for house numbers doesn't work in many countries, as does the zip code thing, though
to be fair you can and sometimes need to do maths to IP addresses, but yeah your point stands
