If you've earned a CDL endorsement — or you're working toward one — you may be wondering where that credential actually appears on your physical license. The answer is straightforward in principle, but how it looks in practice depends on your state's license format and the type of endorsement involved.
A CDL endorsement is an authorization added to a commercial driver's license that permits the holder to operate specific types of vehicles or transport certain cargo beyond what the base CDL covers. Federal regulations, administered through the Federal Motor Carrier Safety Administration (FMCSA), set the categories. States then issue the actual credentials.
Common endorsement codes include:
| Code | What It Covers |
|---|---|
| H | Hazardous materials (HAZMAT) |
| N | Tank vehicles |
| P | Passenger vehicles |
| S | School bus |
| T | Double/triple trailers |
| X | Combination of tank and HAZMAT |
These codes are standardized federally, which means the letter designations themselves are consistent across states — even when the physical license format differs.
On most U.S. driver's licenses, endorsements appear in a designated field on the front of the card — typically labeled "Endorsements" or abbreviated as "Endors." This field displays the relevant letter codes side by side (for example, "HN" if a driver holds both HAZMAT and tank vehicle endorsements).
Some states print this field on the front of the license. Others place it on the back. A few older license formats include a separate section for restrictions and endorsements together, though these are distinct categories. 🪪
Restrictions — such as corrective lenses requirements or no highway driving — are typically listed separately, often in a field labeled "Restrictions" or "Rest." Endorsements and restrictions are not the same thing and are not interchangeable, even if they appear near each other on the card.
Earning an endorsement generally requires:
Once a driver passes the required tests and any background screenings, the state DMV updates their CDL record and issues a new or updated physical license reflecting the added endorsement code. Some states mail an updated card; others require an in-person visit.
Driver's license formats are not uniform across states. While AAMVA (the American Association of Motor Vehicle Administrators) provides guidance on card layout and data fields, individual states control the visual design. This means:
If you've recently passed an endorsement test but haven't received your updated card yet, your driving record — obtainable through your state DMV — will reflect the endorsement before the physical license does. Employers, enforcement officers, and regulators can verify endorsements through that record.
Several factors affect exactly how endorsements appear on your license:
For HAZMAT specifically, the endorsement won't appear until the TSA clearance is complete, regardless of whether the knowledge test has been passed. The timeline for that clearance varies.
A blank endorsement field — or one that reads "NONE" — simply means no endorsements are currently active on that license. This is normal for standard Class D (non-commercial) licenses, which don't carry CDL endorsements at all. It also applies to CDL holders who haven't yet added endorsements beyond the base license.
If you believe an endorsement should appear but doesn't, the place to start is your state DMV's driver record — not the physical card itself. The record is the authoritative source. The card reflects it, but processing and printing take time.
What exactly your endorsements look like — and where they sit on the card — comes down to your state's current license design and your own credential history. Those specifics live with your issuing state.
