The Complete Guide to Renewing Your Texas Driver's License Without the Headaches
By Robert Thorne
Q1: What is the driver license audit number (DD) and where do I find it?
The audit number, often marked as "DD" on your card, is a security tracking sequence numbering 16 to 20 digits. On newer horizontal Texas licenses, it sits along the bottom edge or directly beside your photograph. This number validates physical possession of the original credential during digital transactions.
Q2: How early can I renew my Texas driver's license before it expires?
You can submit your renewal up to two years prior to the expiration date printed on the card. Taking advantage of this generous timeline lets drivers schedule in-person appointments at their convenience or renew online long before seasonal summer and holiday office rushes.
Q3: Can I update my residential address during an online renewal?
Yes. The digital portal allows address adjustments during the transaction. You must confirm that you remain a permanent Texas resident and provide a valid residential street address. P.O. boxes are accepted solely as secondary mailing addresses, not physical residences.
