Where to Find Endorsements on Your CDL Card

Your endorsements appear in a specific box on the front or back of your CDL card, depending on your state. Most states print them on the back under a heading like "Endorsements" or "Restrictions," listed as letter codes (H, N, T, X, P, S, etc.). Each letter stands for a different type of cargo or driving permission you have earned.

The exact location and format varies by state. Some states list endorsements vertically in a single box; others spread them across the card. If you cannot locate them when ready, check the back of the card first — that is where most states place them. Your card should also show the date each endorsement expires, which may differ from your CDL expiration date.

If your card is damaged, faded, or you cannot read the endorsement codes clearly, contact your state DMV to request a replacement card or a written record of your current endorsements. Do not assume you have an endorsement you think you earned; the official record on your card or in the DMV database is what matters to law enforcement and employers.

Key Takeaways

  • Endorsements appear as letter codes on the back of most CDL cards, in a box labeled "Endorsements" or "Restrictions."
  • Each letter code (H, N, T, X, P, S, and others) represents a specific type of cargo or driving authority you are permitted to handle.
  • Endorsement expiration dates may differ from your CDL expiration date, so check both to avoid driving with an expired endorsement.
  • If you cannot read your endorsements clearly or believe they are missing, request a replacement card or official record from your state DMV.
  • Your employer or a law enforcement officer can also confirm your endorsements by running your license through the state database.

Understanding Common Endorsement Codes

The most common endorsement codes are H (hazardous materials), N (tank vehicles), T (double and triple trailers), X (combination of hazmat and tank), P (passenger), and S (school bus). Some states add regional codes for specific cargo types or vehicle configurations. The code itself is always a single letter, and you may have multiple endorsements listed on your card at once.

Hazmat (H) and tank (N) endorsements require background checks and written exams beyond the standard CDL test. Passenger (P) and school bus (S) endorsements also require additional testing and, in many states, fingerprinting or medical clearance. If you see an endorsement on your card that you do not remember earning, contact your DMV — it may indicate a previous holder's record was not cleared, or there may be an error in the system.

Some states also use restriction codes (letters like L, Z, or numbers) to show what you cannot do, rather than what you can. For example, an "L" restriction might mean you cannot drive certain types of vehicles. Read the legend on the back of your card or ask your DMV which codes are endorsements and which are restrictions.

How to Verify Endorsements Through Your State DMV

The most reliable way to confirm your endorsements is to check your driving record through your state DMV website or by visiting a DMV office in person. Most states offer online driving record lookup using your license number, date of birth, and sometimes a PIN or last four digits of your Social Security number. The record will show every endorsement currently active on your license, along with issue and expiration dates.

If you cannot access the online system or need a certified copy of your record, visit your local DMV office or call their CDL unit directly. Have your license number and state of issuance ready. Some states charge a small fee (typically $5 to $15) for a certified driving record, but an unofficial online check is usually free. A certified record is useful if you need to show an employer or a court what endorsements you hold.

If you are explore for a job that requires specific endorsements, ask the employer whether they prefer to run your license themselves through the state database or whether they want you to provide a copy of your driving record. Many large carriers and transportation companies have direct access to state records and can verify your endorsements when ready.

What to Do If an Endorsement Is Missing or Incorrect

If your card shows endorsements you did not earn, or if an endorsement you know you have is missing, contact your state DMV when ready. Bring your CDL card, your original test records or certificates (if you have them), and a form of identification. The DMV will investigate whether the error is in the card printing, the database, or both.

Corrections usually take one to three weeks. If the endorsement is missing, the DMV may reissue your card at no charge or for a small fee. If an endorsement appears that should not be there, the DMV will remove it and issue a corrected card. In the meantime, do not drive with an endorsement you do not hold — law enforcement can cite you for operating outside your license class, which can result in fines and points on your record.

If you earned an endorsement in another state and moved to a new state, you will need to transfer your CDL to your new state of residence. The new state will issue a new card with your endorsements transferred, but the process can take several weeks. During the transfer period, your old CDL remains valid as long as you are not a resident of the new state. Check your new state's rules on how long you have to transfer before your out-of-state license expires.

Endorsement Expiration and Renewal Timing

Some endorsements expire on the same date as your CDL, while others have separate expiration dates. Hazmat (H) endorsements, for example, must be renewed every five years and require a new background check and written test each time. Tank (N) and passenger (P) endorsements typically renew with your CDL but may have their own renewal requirements in some states.

Check your card for the expiration date printed next to each endorsement. If an endorsement expires before your CDL does, you must renew it separately or you will lose that authorization. For example, if your CDL expires in 2027 but your hazmat endorsement expires in 2025, you must renew the hazmat endorsement in 2025 or you cannot haul hazardous materials after that date, even though your CDL is still valid.

Set a calendar reminder for three months before any endorsement expiration date. Contact your state DMV to find out what tests, fees, or background checks you need to renew. Some endorsements can be renewed by mail or online; others require an in-person visit. Do not wait until the expiration date to start the process — renewal can take several weeks, and driving with an expired endorsement is illegal.

Reading Endorsements on Out-of-State or Transferred Licenses

If you hold a CDL from another state, the endorsement codes are the same across all states — H, N, T, X, P, S, and others mean the same thing everywhere. However, the location of the endorsement box on the card and the format of the text may look different. Some states print endorsements horizontally; others print them vertically. Some states use a separate "Endorsements" section; others combine endorsements and restrictions in one box.

If you are unsure whether an out-of-state card shows an endorsement, look for the letter codes in any box labeled "Endorsements," "Restrictions," or "Special Codes." If the card is old or the print is faded, request a certified driving record from that state's DMV. When you transfer your CDL to a new state, the new state will reprint your endorsements on the new card in that state's format, but the endorsements themselves do not change.

Frequently Asked Questions

Can I drive with an endorsement that is about to expire?

No. Once an endorsement expires, you cannot legally operate a vehicle or carry cargo that requires that endorsement, even if your CDL itself is still valid. If you are caught driving with an expired endorsement, you can be cited for operating outside your license class. Renew at least three months before the expiration date to avoid a gap in coverage.

What if my employer says I need an endorsement I do not have?

You will need to earn that endorsement by passing the written test and any required background checks or medical exams. Contact your state DMV to schedule the endorsement test. The process typically takes one to four weeks, depending on how quickly you can schedule the test and whether you need a background check or hazmat clearance. Some employers will pay for the test or training; ask before you pay out of pocket.

Do endorsements transfer if I move to a new state?

Yes, but you must transfer your CDL to your new state of residence. The new state will issue a new card with your endorsements transferred over, though the card format and layout will match your new state's design. The transfer process usually takes two to four weeks. Your old CDL remains valid until it expires or until you become a resident of the new state, whichever comes first.

How do I know if I have a restriction instead of an endorsement?

Restrictions are usually marked with different letters or symbols than endorsements and appear in the same box on your card. Restrictions tell you what you cannot do; endorsements tell you what you can do. Check the legend or key printed on the back of your card, or call your state DMV to clarify which codes on your card are endorsements and which are restrictions.

Can I see someone else's endorsements if I have their license number?

No. Driving records are private information protected by state law. Only the license holder, their employer (with permission), law enforcement, and certain government agencies can view a full driving record. If you need to verify someone's endorsements for hiring or legal purposes, ask them to provide a certified copy of their driving record or authorize you to request it from the DMV.
