What Your Illinois Driver License Number Means

Your Illinois driver license number is a unique 12-digit identifier printed on the front of your license. It is not the same as your Social Security number, and it does not encode your birth date or other personal information the way some state systems do. Illinois assigns these numbers sequentially based on when you first received a license in the state, combined with a check digit for verification.

The number appears in the upper right corner of your physical license and is also listed on your digital license if you use the Illinois Secretary of State mobile app. You will need this number to renew your license, report it lost or stolen, check your driving record, or respond to traffic citations.
