@Questioner - you'd have to ask DMV - it's not considered ID to everyone.
for 'zample:

but I'd reckon it's because it's hard as hell to get somebody else's birth certificate.
In fact, the only time I've ever heard of any birth certificate scam in my lifetime, it was coming out of crackpot teabaggers mouths LoLz..............so I'm not too sure it's like a thing you can really do.
edit : you are right about getting a passport, though - best effing investment you can make - it's saved my butt MANY a time, that thing
