Actually----the date of birth is used in the software and the SSN you use has to match the IRS records. So you have to be careful in My Info when you enter a date of birth and a SSN. E-files can be rejected if there is an error with those.
But --- you "verify your identity" to e-file by entering your past year AGI, which the IRS matches up to the tax return that was filed using that SSN for the previous year.
