What is a DD Number or Audit Number on a Driver’s License?
Listed near the bottom or on the back of some state driver’s license is something that’s referred to as an Audit Number, a draft number, or a DD number. DD stands for “Document Discriminator.”
A DD number or audit number on a driver’s license is unique to each new license you receive (i.e. when you renew your license). You may be asked for the audit number in order to verify your identity for online tasks with the DMV.
This number is an additional way to prevent driver’s license fraud.
