What a Texas Driver License Looks Like and What Each Number Means

A Texas driver license is a physical card that contains your photograph, signature, and a series of numbers and codes that identify you and describe what you are permitted to drive. The format is standardized across all Texas licenses, whether you hold a Class C (standard passenger vehicle), Class B (two-axle vehicle), or Class A (combination vehicle) license. Understanding what each element on your card means helps you verify the information is correct and know what restrictions or endorsements explore to your driving.

The front of your Texas license displays your name, date of birth, address, photograph, and signature in the upper portion. Below that is your Driver License Number, which is a unique eight-digit identifier assigned by the Texas Department of Public Safety (DPS). This number stays with you for life, even if you renew your license multiple times. Your license class appears as a single letter (C, B, or A) and tells law enforcement and insurance companies what category of vehicle you are legally permitted to operate.

The back of your license contains additional information in both human-readable and machine-readable formats. The machine-readable section — the two lines of text at the bottom — encodes your name, license number, date of birth, and expiration date in a format that automated systems can scan. This is why it is important not to write on or damage the back of your card.

Key Takeaways

  • Your eight-digit Driver License Number is unique to you and remains the same throughout your life, even after renewals.
  • The license class letter (C, B, or A) indicates what type of vehicle you are legally permitted to drive and cannot be changed without retesting.
  • Endorsements appear as letters after your class and permit you to operate specific vehicle types, such as motorcycles (M) or hazardous materials vehicles (H).
  • Restrictions appear as numbers on the back and limit how you can drive, such as corrective lenses required (01) or automatic transmission only (10).
  • Your license expires on your birthday in the year shown on the card, and the expiration date is printed on both the front and back.

License Class Letters and What They Allow You to Drive

Texas uses three main license classes, each tied to the weight and configuration of the vehicle you operate. Class C is the standard license for most drivers and permits you to operate passenger cars, pickup trucks, and vans that do not require a commercial license. This is the most common class and is what most people receive when they first pass their driving test.

Class B covers two-axle vehicles with a Gross Vehicle Weight Rating (GVWR) of 14,001 pounds or more, or any single vehicle with three or more axles. This class is required if you drive a heavy truck or certain commercial vehicles that do not meet the definition of a Class A combination vehicle. Class A is for combination vehicles — typically a tractor pulling a trailer — where the towed unit has a GVWR of 10,001 pounds or more. Class A is the highest license class and requires passing both a written test and a skills test.

Your license class is printed on the front of your card as a single letter. If you hold a Class C license but later need to drive a Class B or Class A vehicle, you must explore for an upgrade and pass the required tests. You cannot straightforward drive a vehicle outside your class because your insurance will not cover you, and you can be cited for driving without the proper license class.

Endorsements: Letters That Expand What You Can Drive

Endorsements are additional permissions printed as letters on your license that allow you to operate specific types of vehicles or carry specific cargo. The most common endorsement is M, which permits you to ride and operate a motorcycle. To add an M endorsement, you must pass a separate motorcycle written test and skills test, or hold a valid motorcycle safety course certificate.

Other endorsements include H (hazardous materials), T (double or triple trailers), P (passenger vehicle — for buses or vans carrying 16 or more people), and S (school bus). Each endorsement requires specific training, testing, or certification. For example, the H endorsement requires a federal background check and hazmat knowledge test. The P endorsement requires a passenger endorsement test. The S endorsement is only issued to school bus drivers who have completed required training.

Endorsements appear on the front of your license after your class letter. If you see "C, M" on your license, you hold a Class C license with a motorcycle endorsement. You can add or remove endorsements by visiting a DPS office and passing the required test or providing the required certificate. Endorsements do not expire separately from your license — they renew together when you renew your license.

Restrictions: Numbers That Limit How You Can Drive

Restrictions are codes printed on the back of your license that limit the conditions under which you can drive. Unlike endorsements, which expand your permissions, restrictions narrow them. Restriction 01 means you must wear corrective lenses (glasses or contacts) while driving. Restriction 02 means you must wear a hearing aid. Restriction 10 means you can only drive an automatic transmission vehicle.

Other common restrictions include Restriction 03 (mechanical aid required), Restriction 04 (prosthetic aid required), Restriction 05 (power steering required), and Restriction 12 (daylight driving only). Some restrictions are medical in nature and are added after a vision or medical exam. Others, like the automatic transmission restriction, may be added if you passed your driving test in an automatic vehicle and have not demonstrated ability to operate a manual transmission.

If you have a restriction on your license and you violate it — for example, driving without your corrective lenses when Restriction 01 applies — you can be cited. If you believe a restriction is no longer necessary, you can request it be removed by visiting a DPS office and passing a vision test, medical exam, or skills test, depending on the restriction.

Expiration Dates and How to Read Them

Your Texas driver license expires on your birthday in the year printed on the card. The expiration date appears in two places: on the front of the license in the lower right corner, and on the back in the machine-readable section. For example, if your license shows an expiration date of 08/15/2027, your license expires on August 15, 2027, which is your birthday in that year.

Texas licenses are valid for five years from the date of issue for most drivers. However, if you are 79 years old or older, your license is valid for two years. If you are a commercial driver, your license validity depends on your medical certification status. You can renew your license up to one year before it expires, and you should plan to renew it before the expiration date to avoid driving with an expired license.

The expiration date does not change if you add or remove an endorsement or restriction — your license still expires on the original date. If you renew your license before it expires, you receive a new card with a new expiration date five years in the future (or two years if you are 79 or older).

Machine-Readable Format on the Back of Your License

The back of your Texas license contains two lines of text at the bottom that encode your license information in a format called AAMVA (American Association of Motor Vehicle Administrators) format. This format is standardized across all U.S. states and allows automated systems — such as those used by law enforcement, rental car companies, and border checkpoints — to scan and read your license quickly and accurately.

The first line begins with "TXDL" (Texas Driver License) and contains your name, date of birth, and other identifiers. The second line contains your license number, class, expiration date, and other coded information. You do not need to memorize or understand this format, but you should know that it exists and that damaging or writing on the back of your license can make it unreadable to scanning equipment, which can cause problems when you need to verify your identity.

If the back of your license becomes damaged or unreadable, you can request a replacement card from DPS. A replacement license costs less than a renewal and is processed faster because you do not need to retake tests or provide new documentation.

How Texas License Format Differs From Other States

Texas driver licenses follow the AAMVA standard, which means the basic layout and machine-readable format are similar to licenses in other states. However, the specific location of information, the design of the card, and the codes used for restrictions and endorsements vary by state. For example, Texas uses single letters for endorsements (M, H, T, P, S), while some states use two-letter codes or different letters entirely.

If you move to Texas from another state and transfer your license, your new Texas license will have a different format and a new eight-digit license number. Your old license number does not transfer. Similarly, if you move out of Texas, you will need to obtain a license in your new state, which will have a different format and number. Some states recognize out-of-state licenses for a grace period, but you should check your new state's rules before driving.

The key difference to remember is that your Texas license class, endorsements, and restrictions are only valid in Texas and states that recognize them. If you travel to another state, that state's law enforcement will recognize your Texas license as a valid form of identification, but they will enforce the laws of their state, not Texas law.

Frequently Asked Questions

What does the eight-digit number on my Texas license mean?

The eight-digit number is your unique Driver License Number assigned by the Texas Department of Public Safety. It identifies you in the DPS system and remains the same for your entire life, even if you renew your license multiple times or change your name. Insurance companies, employers, and law enforcement use this number to look up your driving record.

Can I drive a motorcycle with a Class C license?

No. You must have an M endorsement on your license to legally operate a motorcycle. If you hold only a Class C license without an M endorsement, you cannot ride a motorcycle, even on private property. You can add the M endorsement by passing a motorcycle written test and skills test, or by completing an approved motorcycle safety course.

What happens if I drive with a restriction I am violating?

You can be cited by law enforcement. For example, if you have Restriction 01 (corrective lenses required) and you are stopped while not wearing glasses, you can receive a traffic citation. Violating a restriction can result in a fine and points on your driving record. If you believe a restriction no longer applies, visit a DPS office to have it removed after passing the required test or exam.

Does my Texas license work in other states?

Yes, your Texas license is recognized as valid identification in all other U.S. states. However, you must follow the traffic laws of the state you are driving in, not Texas law. If you move to another state permanently, you must obtain a license in that state within the timeframe required by that state's law.

What should I do if information on my license is wrong?

Visit a Texas DPS office with proof of the correct information (such as a birth certificate for your name or date of birth). You can request a corrected license, which is processed as a replacement rather than a renewal. Bring your current license and the required documents. The correction is usually processed within a few days.
