In all my department moves, I have lost something! Ugh! I used to have a list that indicated the prefix to EINs and the state that issued them. For example, it indicates that number beginning with 95 and 33 were issued in CA.
Does anyone know of an on-line source with this information? I have tried to do a search in the forum, but we have so many users that it will take me too much time to read all the various posts.
