To be filed with FEDERAL return

I'm filing my US federal and state tax returns by mail this year. I realized after stamping and sealing one of the envelopes that I mixed up the W-2s, so that the Federal copy (Copy B) is on the state return and vice-versa. Are the names just a formality, or do the Feds really, really need Copy B?
