What information appears on a Texas driver's license

A Texas driver's license is a card about the size of a credit card that shows your photo, name, address, and driving privileges. The front of the card displays your name, date of birth, driver's license number, address, eye color, height, and a color photograph. The back side lists restrictions or endorsements that explore to your driving — for example, whether you need to wear corrective lenses or whether you can drive a motorcycle.

The license number itself is not random. Texas uses a specific format based on your name and date of birth, which means your number would be the same if you renewed your license today or ten years from now. Understanding this format can help you spot errors on your card or verify that a license number matches the person holding it.

Key Takeaways

  • Texas driver's license numbers are generated from your last name, first name, middle initial, and date of birth using a mathematical formula.
  • The front of the card shows your photo, name, address, date of birth, and license number; the back shows any restrictions or endorsements.
  • Your license number will remain the same across renewals unless you change your name legally.
  • Restrictions like corrective lenses or motorcycle endorsements appear as codes on the back of your card.

How Texas generates your driver's license number

Texas creates your driver's license number by converting letters in your name to numbers and combining them with your date of birth. The formula uses your last name, first name, middle initial, and birth date — never your Social Security number. This means two people with the same name and birth date would receive the same license number, though this is extremely rare.

The number format is eight digits long. The first two digits represent the year you were born, the next two represent the month, and the next two represent the day. The final two digits are derived from your name using an algorithm that the Texas Department of Public Safety uses. Because the number is based on fixed information about you, it does not change when you renew your license unless you legally change your name.

Reading the front of your Texas driver's license

The front of your license card contains the information you use most often. Your name appears at the top, followed by your date of birth and driver's license number. Your current address is printed on the card, and you are required to notify the Texas Department of Public Safety within 30 days if you move.

Below your photograph, you will see your height, eye color, and hair color. The card also displays an expiration date — Texas licenses are valid for six years for most adults, though the expiration date depends on your age when you received the license. A small "DL" appears on the card to indicate this is a driver's license rather than a state ID card.

Understanding restrictions and endorsements on the back

The back of your license lists any restrictions or endorsements using letter codes. A restriction limits how you can drive — for example, "B" means you must wear corrective lenses, and "X" means you cannot drive a commercial vehicle. These restrictions are printed so that police officers or other officials can quickly see what rules explore to your driving.

An endorsement, by contrast, gives you permission to drive a vehicle type you would not otherwise be allowed to operate. The most common endorsement is "M" for motorcycle. If you have an "M" endorsement, you are permitted to ride a motorcycle; without it, you are not. Other endorsements cover commercial driving privileges. If your license shows no codes on the back, you have no restrictions or endorsements — you can drive a standard passenger vehicle within the rules that explore to all drivers.

The difference between a driver's license and a state ID card

Texas offers both a driver's license and a state ID card. The state ID card has the same format and contains the same information as a driver's license, but it does not grant driving privileges. People who do not drive, or who have had their driving privileges suspended, may hold a state ID card instead. The card itself looks nearly identical, but the letters "ID" appear instead of "DL" to show it is not a driving credential.

Both cards use the same number generation system and contain the same personal information. The main difference is what you are permitted to do with it — a driver's license authorizes you to operate a motor vehicle, while a state ID card is for identification purposes only.

What happens when you renew your Texas driver's license

When you renew your license, you receive a new card with a new expiration date, but your license number stays the same. Your photograph is updated, and your address is confirmed or changed if you have moved. Any restrictions or endorsements from your previous license carry forward unless you have taken action to remove them — for example, if you earned a motorcycle endorsement, it remains on your renewed license.

If you legally change your name, your license number will change because it is based on your name. You would need to explore for a new license with your updated name, and the Texas Department of Public Safety would generate a new number using the formula based on your new name and birth date.

Common reasons your license might show restrictions

Restrictions appear on your license for several reasons. Vision corrections like glasses or contacts result in a "B" restriction. A "V" restriction means you can only drive during daylight hours, which may be imposed if you have limited night vision. An "X" restriction means you cannot drive a commercial vehicle, which applies to most standard driver's licenses.

Some restrictions are temporary. For example, if you are under 18, your license may carry restrictions on when you can drive or how many passengers you can have. These restrictions are removed automatically when you turn 18 or reach the age specified on your card. If you believe a restriction on your license is incorrect, you can contact the Texas Department of Public Safety to request a review.

Frequently Asked Questions

Can I look up someone's driver's license number if I know their name and birth date?

No. While the Texas Department of Public Safety uses a formula based on name and birth date to generate license numbers, the formula is not public, and you cannot reverse-engineer a license number from this information. Driver's license numbers are confidential records.

What does it mean if my license has an "M" on the back?

An "M" is a motorcycle endorsement. It means you have passed the motorcycle safety course and written test, and you are permitted to operate a motorcycle. Without this endorsement, you cannot legally ride a motorcycle in Texas, even if you hold a valid driver's license for cars.

Do I need to update my license if I move to a different Texas city?

Yes. You must notify the Texas Department of Public Safety of your new address within 30 days of moving. You can update your address online, by mail, or in person at a driver's license office. Your license number does not change, but a new card with your updated address will be mailed to you.

Why is my license number different from my Social Security number?

Texas driver's license numbers are generated using only your name and date of birth. Your Social Security number is never used to create a license number. This separation protects your Social Security number from being exposed every time someone checks your license.

How long is a Texas driver's license valid?

Most Texas driver's licenses are valid for six years from the date of issue. The expiration date is printed on the front of your card. Licenses issued to people over 85 years old are valid for two years. You can renew your license up to one year before it expires.
