On a driver’s license, “ISS” means issue date — the date your current card was produced by your state’s licensing agency. It’s printed as a month/day/year date, usually near the top or front of the card. The abbreviation comes from the American Association of Motor Vehicle Administrators, which sets the design standard U.S. states follow when they lay out a license.1American Association of Motor Vehicle Administrators.

ISS Is Not the Same as EXP
The field people most often confuse ISS with is EXP, the expiration date. They’re different dates doing different jobs. ISS tells you when the card in your hand was issued. EXP tells you when it stops being valid. One is the start of the clock, the other is when it runs out.
How long that gap runs depends on your state. A standard license is typically valid for anywhere from four to eight years, with some states allowing longer or shorter periods depending on your age.
When the Issue Date Changes
Your ISS date isn’t fixed to the first license you ever got. It resets every time your state produces a new physical card for you. That includes:
- Renewing your license at the end of a cycle
- Replacing a lost, stolen, or damaged card
- Updating your name, address, or other information
- Upgrading to a REAL ID compliant card
So if you renewed last month, your ISS date will show last month, even though you’ve been driving for twenty years. The date reflects the card, not your driving history.
Why the Issue Date Can Matter
Most people look at EXP and ignore ISS, but the issue date does practical work in a few situations.
It confirms a renewal went through. If you renewed online or by mail and the new card arrives, the ISS date should match that transaction. If it doesn’t, something is off.
It helps banks, employers, and agencies verify that your ID is current. A card issued years ago with a far-off expiration date can sometimes prompt follow-up questions or a request for a second form of ID.
It can matter after an update. When you change your name or address, the ISS date resets. Insurers and courts occasionally use that date to confirm when your credentials were last updated.
And it tells you which card is the real one. If you reported a license lost or stolen and then found the old one, the card with the newer ISS date is the valid one.
The Other Abbreviations on Your License
While you’re decoding ISS, the rest of the short labels on the card follow the same AAMVA standard.1American Association of Motor Vehicle Administrators. AAMVA DL/ID Card Design Standard (2020) Placement varies by state, but the labels themselves are consistent.
- DOB — date of birth.
- EXP — expiration date, when the license stops being valid.
- DL — your driver’s license number in the state’s system.
- DD — document discriminator, a unique number tied to that specific physical card. It distinguishes your current card from any previous ones issued to you and is used for fraud prevention and inventory tracking.
- CLASS — the class of vehicles you’re authorized to drive. For most drivers this is Class C or its state equivalent, which covers standard passenger cars and light trucks. Classes A and B authorize larger commercial vehicles.
- RSTR — restriction codes that limit how or when you can drive. The most common is the corrective lenses requirement, meaning you must wear glasses or contacts behind the wheel. Restriction codes aren’t fully standardized, so the same letter can mean different things in different states.
- END — endorsement codes that expand your privileges beyond the base class, such as a motorcycle or school bus endorsement.
If Something on Your License Doesn’t Look Right
Your state’s DMV website is the most reliable place to decode anything on the card. Most states publish a labeled sample license and post their restriction and endorsement tables online, and the state driver manual (usually a free PDF) explains every marking that can appear on a license issued there. If you suspect a code or date is wrong on your card, call or visit your local DMV office before you need to rely on the license.
