Rejected e-file code FW2-502

I have tried to e-file my taxes twice now and they keep getting rejected with the code FW2-502. I understand that this code means the EIN numbers don't match the IRS records. I'm wondering if this is an error though, I have the same 3 W2s as last year, I have confirmed all 3 are correct, and when I review the error it's not mentioning just 1 W2 but that all 3 are wrong. That doesn't seem right. Any ideas?
