What a Texas Driver License Number Looks Like

Your Texas driver license number is an eight-digit code printed on the front of your card. It is not random — each digit follows a pattern based on your name and date of birth. Understanding this format helps you verify your license is correct when you receive it, and it explains why your number looks the way it does.

The eight digits break into two parts: the first six digits come from your name, and the last two come from your birth year. Texas has used this same format since 1996, so whether you hold a Class C license, a commercial license, or any other type, your number follows these rules.

Key Takeaways

  • Texas driver license numbers are eight digits long, with the first six derived from your last name and first name using a specific algorithm.
  • The last two digits represent your birth year, using only the final two numbers (for example, 1985 becomes 85).
  • Your number is generated automatically by the Texas Department of Public Safety when you receive your license — you cannot choose it.
  • The format is the same across all Texas license types, including Class C, commercial, and motorcycle licenses.
  • If your number contains letters instead of all numbers, you may be looking at an older license or a different document.

How the First Six Digits Are Generated

The first six digits of your Texas driver license number come from a mathematical formula applied to your last name and first name. The Texas Department of Public Safety uses a specific coding system that converts letters into numbers based on their position in your name.

The exact algorithm is not published in detail, but the result is that two people with the same name and birth year will have the same license number — which is why the state uses additional verification methods like your address and date of birth when confirming your identity. If you change your name through marriage or legal petition, you will receive a new license number when you renew, because your name has changed and the formula produces a different result.

This system means your license number is tied to the name on your process. If there is a typo in your name when you explore, your number will reflect that typo. You can correct it by visiting a Texas Department of Public Safety office with proof of your legal name.

What the Last Two Digits Mean

The final two digits of your Texas driver license number are your birth year, reduced to two digits. If you were born in 1985, those last two digits will be 85. If you were born in 2005, they will be 05.

This two-digit format means the system cannot distinguish between someone born in 1905 and someone born in 2005 based on the license number alone. That is why the state relies on your full date of birth — month and day included — as stored in the Department of Public Safety database, not just the year shown in your number.

When Your License Number Changes

Your Texas driver license number stays the same throughout your life unless your name changes. A name change through marriage, divorce, or legal petition requires you to explore for a new license, and the new license will have a different number because it is generated from your new legal name.

Renewing your license does not change your number. If you renew in person or by mail, your eight-digit number remains identical on your new card. The only exception is if you have made a legal name change between renewals.

If you lose your license and request a replacement card, your number does not change. The replacement card is a duplicate of your existing license with the same number, just a new physical card.

How to Verify Your License Number Is Correct

When you receive your new Texas driver license in the mail, check that the eight-digit number on the front matches the number on your temporary paper license or your receipt from the Department of Public Safety office. The number should be consistent across all documents related to that license.

If your number appears to have letters in it, or if it does not match what you were told at the office, contact the Texas Department of Public Safety to verify. You can call the Driver License Division at 1-888-589-6789 or visit a local office with your license and proof of identity.

Keep in mind that older Texas licenses issued before 1996 may have used a different format. If you are looking at a very old license, the number may not follow the eight-digit pattern described here.

License Numbers on Other Texas Documents

Your Texas driver license number is also your identification number for other Department of Public Safety documents. If you hold a commercial driver license (CDL) or a motorcycle endorsement, the same eight-digit number appears on those credentials.

This number is separate from your Social Security number and your Texas identification card number (if you have one). Each document has its own unique identifier, though they may be linked in the state database.

Frequently Asked Questions

Can I request a specific driver license number?

No. The Texas Department of Public Safety generates your number automatically based on your name and birth year. You cannot choose or request a different number.

What if I was born in 1900 or earlier?

The two-digit year format creates ambiguity for people born in the 1800s or very early 1900s. The Department of Public Safety handles this by storing your complete birth date in its database; the license number itself shows only the two-digit year, but the full date is used for verification.

Does my license number change if I move to a different state?

Your Texas license number is specific to Texas. If you move and obtain a driver license in another state, that state will issue you a new number in its own format. Your Texas number remains on your Texas license if you keep it as a secondary ID.

Why do two people with the same name have the same license number?

Because the number is generated only from your name and birth year, two people with identical names and birth dates will have identical license numbers. The state uses your full address and other identifying information in its database to distinguish between them.

Is my driver license number the same as my driver license case number?

No. Your eight-digit license number is printed on the front of your card. Your case number is an internal reference used by the Department of Public Safety for administrative purposes and appears on receipts and correspondence, but not on the license itself.
