Of the half dozen or so I tested (not super scientifically, but with a moderately sized sample dataset that I ran through several APIs), Smarty seemed to be the most accurate: https://www.smarty.com/
My main reference point with them is that their free IP geolocation database is terrible, and every time I find a geolocation error on a website, it's almost always because they're using that DB (https://dev.maxmind.com/geoip/geolite2-free-geolocation-data).
I've come to equate MaxMind with "bad data"... would be afraid to trust them with anything, unless their paid services are dramatically better.

It was expensive though.
And there's the Google Maps API, of course:https://developers.google.com/maps/documentation/address-val...
I thought Maxmind was the gold standard or am I old?
