EIN Prefixes: Is there a state-specific list?

Answered by: 

Are there state specific 2 digit pre-fixes for EIN numbers allocated to businesses? And if so what are they or how could I obtain them?

You made me go looking! I included this table in an article back in 1995. You'll find it at the reference below. Or, as a shortcut, here is the prefix table:
