How to map an address (state) in the US?


if I have a building in the US how would I map the address? The question is specifically around the state? JOSM doesn’t seem to provide a tag for the state, e.g. addr:state? 't there a tag for this?


The state should be mapped with a boundary relation. This lets software calculate what objects are within the boundary. So it is not necessary to tag the state (or country) on every single address.

Though the wiki does list addr:state, so you could use that if you want.
