the I-9 form asks for a document number as does the e-verify system for new employees. In Texas, we have a 20 digit DD number (the letters DD: followed by 20 digits) near the bottom of the card (in the middle, not lower right or on the back). The DD is called the audit number and also called the document discriminator. Would this be the number that we would enter under "Document Number" for driver's license?
