It's a good point, but the challenge is we sometimes just get street1 from a utility without city/state/postal. We tried USPS and geocoding libraries, but they fail because they often pick a random-ish city which likely will not match.

I would say sometimes data needs to be rejected as invalid. I don't know the exact scenario here, but you'll never be able to know if a street number/name alone is unique as almost any street will have dozens or more matches across the country.

If people are jamming their entire address into address line 1, that is also solved by CASS.

How would a llm know the town any better then the other alternatives?
