What you see on the front and back of your driver's license
Your driver's license has information printed on both sides, and each side serves a different purpose. The front holds your identity and driving privileges — the details law enforcement and ID checkers use. The back contains emergency contact information, organ donation status, and restrictions or endorsements that affect what you're legally allowed to drive.
Understanding what each side contains helps you know what information you're sharing when you hand over your license, and it shows you what details the state has on file about you. If any information is wrong, you'll know which side to check and what to correct.
Key Takeaways
- Your license front displays your photo, name, address, date of birth, signature, and license number — the core identity information used for age verification and traffic stops.
- The back side shows your emergency contact, organ donation choice, and any medical alert symbols, plus restrictions like corrective lenses or manual transmission only.
- Endorsements on the back (like "H" for hazmat or "P" for passenger vehicles) indicate what commercial or specialized driving you're permitted to do.
- Address changes, name corrections, and updates to medical information require a visit to your state's DMV or equivalent agency.
- Real ID compliant licenses have a star or marking on the front that shows you can use it for federal purposes like airport security.
The front of your driver's license
The front contains the information that identifies you and proves you have a valid license to drive. Your photograph is the largest element — it must be current enough that you're recognizable, and most states require a new photo every 8 to 10 years. Below or beside the photo, you'll see your full legal name, date of birth, and current address.
Your license number appears on the front and is unique to you in your state. This number is what law enforcement enters when they run your license during a traffic stop. Your signature is also printed on the front — it should match the signature you provided when you applied or renewed. The issue date and expiration date show when your license was issued and when it expires; driving on an expired license is illegal, even if you've applied for renewal.
In the top corner or elsewhere on the front, you may see a Real ID star or marking if your license is Real ID compliant. This symbol means your license meets federal security standards and can be used for domestic air travel and entry to federal buildings. If your license does not have this marking, you'll need a passport or other federal ID for those purposes.
The back of your driver's license
The back side contains information about your health, emergency contacts, and any restrictions on your driving. Your emergency contact — usually a name and phone number — is printed here so first responders can reach someone if you're in an accident. You choose who this is when you explore or renew, and you can update it without renewing your entire license in many states.
Your organ donation status is displayed on the back, usually as a symbol or text. When you renew or explore for a license, you're asked whether you wish to be an organ donor. This choice is recorded on your license and is visible to medical professionals in an emergency. You can change your donation status at any time through your state's DMV.
The back also lists any restrictions that limit how you can drive. Common restrictions include "B" for corrective lenses required, "E" for automatic transmission only, or "D" for daylight driving only. These restrictions are set based on your vision test, medical history, or age, and you must follow them or you can be cited. If a restriction no longer applies — for example, you had eye surgery and no longer need glasses — you can request a vision test to have it removed.
Endorsements and what they mean
Endorsements are letters or codes on your license that show you're permitted to drive certain vehicle types or carry certain cargo. They appear on the back and are different from restrictions — endorsements expand what you can do, while restrictions limit it. Not all licenses have endorsements; they're mainly on commercial driver's licenses (CDLs) or licenses in states that use them for specialized driving.
Common endorsements include "H" for hazardous materials, "P" for passenger vehicles (like buses), "T" for double or triple trailers, and "S" for school bus. If you want to add an endorsement, you typically need to pass a written test and sometimes a skills test specific to that endorsement. Your state's DMV website lists which endorsements are available and what each requires.
Medical alerts and symbols on your license
Some states print medical alert symbols on the back of your license to flag conditions that emergency responders should know about. A common symbol is a red heart or medical alert icon that indicates you have a condition like epilepsy, diabetes, or a heart condition. This alerts paramedics or hospital staff to check your license and take your medical history into account during treatment.
You're not required to disclose medical conditions on your license, but doing so can be lifesaving in an emergency when you're unable to speak. If you have a serious medical condition and want it noted, ask your DMV whether they offer medical alert symbols and what documentation you need to provide. Some states require a doctor's note; others accept your self-report.
What to do if information on your license is wrong
If your name, address, date of birth, or any other information on your license is incorrect, you need to correct it at your state's DMV. Bring documents that prove the correct information — a birth certificate for name or date of birth, a utility bill or lease for address changes. In most states, correcting information on an existing license is faster and cheaper than a full renewal.
If your photo is outdated or you've changed your appearance significantly, you can request a new photo without renewing your entire license in many states. Some states allow you to update your address online or by mail, while others require an in-person visit. Check your state's DMV website for the specific process and documents needed.
Real ID compliance and what the marking means
A Real ID compliant license has a star or other marking on the front that shows it meets federal security standards set by the Department of Homeland Security. Starting in May 2025, a Real ID compliant license or passport is required for domestic air travel and entry to federal buildings. A standard driver's license without the marking is still valid for driving, but you'll need an alternative form of federal ID for those purposes.
When you renew your license, you can request Real ID compliance if your state offers it. You'll need to bring documents proving your identity, Social Security number, and current address — typically a birth certificate, Social Security card, and utility bill. The process takes longer than a standard renewal because of the additional verification, but the cost is usually the same or slightly higher.
Frequently Asked Questions
Can I change my emergency contact without renewing my license?
In most states, yes. You can update your emergency contact information at the DMV without renewing your entire license. Some states allow you to do this online or by mail; others require an in-person visit. Check your state's DMV website for the process and whether there's a fee.
What does it mean if my license has a restriction code I don't understand?
Restriction codes are letters that limit how you can drive — for example, "B" means corrective lenses required, "E" means automatic transmission only. Your DMV paperwork or website should list what each code means in your state. If you disagree with a restriction, you can request a vision or medical test to challenge it.
Is my license still valid if it's expired but I've applied for renewal?
No. An expired license is not valid for driving, even if you've submitted a renewal process. You can only drive on an expired license if your state has issued you a temporary permit or extension while your renewal is being processed. Check with your DMV about whether they offer extensions during processing delays.
Do I need a Real ID license to drive?
No. A standard driver's license is valid for driving in all states. Real ID is required only for domestic air travel and entry to federal buildings. If you don't have a Real ID compliant license, you can use a passport or other federal ID for those purposes instead.
What happens if I lose my license or it gets damaged?
You'll need to request a replacement at your DMV. Bring your Social Security card, proof of address, and any other documents your state requires. A replacement license usually costs less than a renewal and arrives within one to two weeks. Some states allow you to request a replacement online or by mail.
