The back of your Texas driver's license holds your address, restrictions, and endorsements
The back of a Texas driver's license contains information that the front does not: your full address, any restrictions on what you can drive, endorsements that allow you to operate certain vehicles, and a magnetic stripe that stores some of your data. This side is what law enforcement and businesses check when they need your current address or need to confirm you are legally allowed to drive a particular class of vehicle. Understanding what is printed there helps you know what to update if you move, and what each code means if you are stopped or asked to show your license.
Texas prints this information in a specific layout that has remained largely consistent, though the format changed slightly when the state moved to the current Real ID-compliant license design in 2020. If your license is older than that, the back may look different, but the categories of information are the same.
Key Takeaways
- Your address on the back of your license must match your current residence, and you have 30 days after moving to update it with the Texas Department of Public Safety.
- Restrictions are printed as letter codes (like "B" for corrective lenses or "L" for daylight driving only) and are conditions you must follow or your license is invalid.
- Endorsements appear as letter codes (like "H" for hazmat or "P" for passenger transport) and show you have passed additional tests to operate those vehicle types.
- The magnetic stripe on the back stores your name, license number, and address in machine-readable form, which is why it must stay clean and undamaged.
Address section and why it matters
The address printed on the back of your Texas license is your official address on file with the state. This is the address where the Department of Public Safety will mail renewal notices, and it is the address law enforcement sees when they scan your license. If you move and do not update it, you may miss renewal notices or create confusion during a traffic stop.
Texas law requires you to notify the Department of Public Safety within 30 days of a change of address. You can update your address online through the DPS website, by mail, or in person at a driver's license office. You do not need a new physical license card when you change your address — the update is recorded in the state system, and your current card remains valid. However, when you renew your license, the new card will print your updated address on the back.
Restrictions: what the letter codes mean
Restrictions are conditions printed on the back of your license that limit how or when you can drive. Each restriction is shown as a single letter, and you must follow every restriction on your license or you are driving illegally. Common restrictions include:
- B: Corrective lenses required (glasses or contacts)
- D: Daylight driving only
- E: Automatic transmission only
- L: Outside mirror required
- M: Ignition interlock device required
- N: No passengers under 18 (for certain young drivers)
- O: Occupational driving only (limited to work-related trips)
If you have a restriction and violate it — for example, driving at night when your license says daylight only — you can be cited even if you are otherwise driving safely and legally. Restrictions are added when you fail a vision test, when you have a medical condition that limits your driving, or when a court orders them as part of a DWI sentence or other penalty.
Endorsements: additional driving privileges
Endorsements are the opposite of restrictions. They show that you have passed additional tests and are legally permitted to operate certain types of vehicles or transport certain cargo. Endorsements appear as letter codes on the back of your license, and you must have the correct endorsement to legally perform that work or operate that vehicle class.
Common endorsements include:
- H: Hazmat (hazardous materials transport)
- P: Passenger transport (buses or vans carrying passengers for hire)
- S: School bus operation
- T: Double or triple trailers
- X: Combination of hazmat and tank vehicle
Most drivers do not have endorsements because they do not need them. You only need an endorsement if your job or regular driving involves one of these categories. If you want to add an endorsement, you must pass a written test and, for some endorsements, a skills test. You can study for these tests using the Texas DPS study materials, which are free and available online.
The magnetic stripe and what it stores
The back of your Texas license includes a magnetic stripe — the dark band at the bottom of the card. This stripe contains encoded information including your name, license number, address, and date of birth. When a police officer or business scans your license with a card reader, they are reading data from this stripe.
The magnetic stripe must remain clean and undamaged for it to be readable. Do not bend, scratch, or expose it to extreme heat or magnetic fields. If the stripe becomes damaged, your license may not scan properly, which can cause delays during traffic stops or when you are trying to use your license as identification. If your stripe is damaged but the rest of your card is intact, you can request a replacement card from the Department of Public Safety.
What changed with the Real ID license design
Texas began issuing Real ID-compliant driver's licenses in 2020. The back of the newer Real ID license looks slightly different from older licenses — the layout is cleaner, the text is easier to read, and the security features are more advanced. However, the categories of information remain the same: address, restrictions, endorsements, and the magnetic stripe.
If your license was issued before 2020, the back may have a different layout or slightly different formatting, but all the same information is there. You do not need to replace an older license just because it is not Real ID-compliant — it remains valid for driving. However, if you want to use your driver's license as identification for federal purposes (like boarding a domestic flight), you will eventually need a Real ID license. Texas will issue you a Real ID license when you renew, as long as you bring the required documents to prove your identity and residency.
Reading your license in low light or at a distance
The back of your license is printed in small text, which can be hard to read in dim lighting or from a distance. If you need to check your restrictions or endorsements and cannot read the back clearly, you can look up your license information online through the Texas DPS website. You will need your license number and date of birth to access this information.
Law enforcement can also look up your complete license record, including any restrictions or endorsements that may not be when ready visible on the card itself. This is why it is important to keep your license in good condition — if the back is worn, faded, or damaged, officers may have to rely on the state system to verify your information, which takes longer.
Frequently Asked Questions
Do I need a new license card if I move to a different address?
No. You can update your address with the Texas Department of Public Safety without getting a new card. Your current license remains valid. When you renew your license, the new card will print your updated address on the back.
What does it mean if my license has a restriction I do not remember getting?
Restrictions are added by the DPS based on information from your driving record, medical records, or court orders. If you do not understand why a restriction is on your license, you can contact the DPS directly or visit a driver's license office to ask. Some restrictions can be removed if the underlying reason no longer applies — for example, if you had a vision restriction and now pass a vision test.
Can I drive if I have an endorsement but do not use it?
Yes. An endorsement straightforward means you are permitted to operate that vehicle or transport that cargo. You do not have to use it. For example, if you have an "H" endorsement for hazmat but work as a regular delivery driver, you can still drive without transporting hazmat.
What should I do if the magnetic stripe on the back of my license is damaged?
Contact the Texas Department of Public Safety to request a replacement card. You can do this online, by mail, or in person at a driver's license office. Bring your current license and proof of residency. The replacement card will have the same license number and information as your current card.
Is the information on the back of my license the same as what is in the state system?
Mostly, but not always. The back of your card shows your address as of the date the card was issued. If you have updated your address since then, the state system has your new address, but your card still shows the old one. Law enforcement can see both when they look you up. This is why updating your address promptly matters — it keeps the state record current.
