What an Arizona driver's license looks like and what the numbers mean
An Arizona driver's license is a wallet-sized card with your photo, name, and a series of numbers and codes that identify you and describe what you're allowed to drive. The format is standardized across all Arizona licenses issued by the Department of Transportation, though the layout and security features have changed over the years as the state updated its system.
The front of the card displays your photograph, full legal name, date of birth, address, and eye color. Below that are several lines of machine-readable information: your driver's license number, issue date, expiration date, and restrictions or endorsements that explore to your license. The back of the card contains your signature and additional security information.
Key Takeaways
- Your Arizona driver's license number is an eight-digit code that uniquely identifies you in the state system.
- The issue and expiration dates tell you when your license was issued and when you must renew it.
- Restriction codes (like "B" or "D") appear on your license if you have conditions that limit how you can drive.
- Endorsement codes (like "M" for motorcycle or "H" for hazmat) show additional vehicle types you are authorized to operate.
- The barcode on the back encodes your personal information and license status in a machine-readable format.
Breaking down the eight-digit license number
Your Arizona driver's license number is eight digits long and serves as your unique identifier in the state's motor vehicle database. This number is not random — it is generated based on your name, date of birth, and other personal information, though the exact algorithm is not public. The number stays the same throughout your life unless you request a replacement card for damage or loss.
When you renew your license, your number does not change. If you move to Arizona from another state and get an Arizona license, you receive a new eight-digit number specific to Arizona. This number appears on every document related to your driving record, insurance claims, and traffic citations.
Understanding issue and expiration dates
The issue date is when your current license card was printed and mailed to you. The expiration date is when that license is no longer valid for driving. Arizona driver's licenses are typically valid for twelve years from the issue date, though this can vary depending on your age at issuance and whether you have a commercial license.
You can continue to drive legally until midnight on your expiration date. After that, you cannot legally operate a vehicle in Arizona, even if you have applied for renewal. If you are stopped by law enforcement with an expired license, you may face a citation. Many people renew their license several months before expiration to avoid gaps in validity.
What restriction codes mean
Restriction codes are single letters that appear on your license if you have conditions limiting how you can drive. Common Arizona restrictions include:
- B — Corrective lenses required (glasses or contacts)
- D — Daylight driving only
- E — Automatic transmission only
- F — Outside mirror required
- K — Ignition interlock device required
- L — Vehicles without air brakes only
If you have a restriction on your license, you must follow it while driving. Violating a restriction — for example, driving at night when your license says daylight only — is a separate traffic violation. If you believe a restriction on your license is incorrect, you can contact the Arizona Department of Transportation to request a hearing or correction.
What endorsement codes mean
Endorsement codes are letters that show you have passed additional tests and are authorized to operate certain vehicle types beyond a standard passenger car. These appear on your license as "Endorsements:" followed by one or more letters. Common Arizona endorsements include:
- M — Motorcycle
- H — Hazardous materials (hazmat)
- P — Passenger vehicle (for commercial licenses)
- T — Double or triple trailers
- X — Hazmat and tanker combined
If you want to add an endorsement to your license, you must pass the written test and, in most cases, a skills test for that endorsement. You cannot legally operate a vehicle type that requires an endorsement if you do not have that endorsement on your license.
The barcode and machine-readable zone
The back of your Arizona driver's license contains a barcode and a machine-readable zone (MRZ) — lines of text and numbers printed in a specific format that law enforcement and other authorized readers can scan. This barcode encodes your name, license number, date of birth, address, and license status. When a police officer or business scans your license, they are reading this barcode.
The barcode also contains information about whether your license is suspended, revoked, or valid. This allows officers and businesses to verify your driving status when ready without calling the state. The barcode format is standardized across all U.S. states, so a reader in another state can interpret an Arizona barcode.
How to tell if your license is a REAL ID
Starting in 2020, Arizona began issuing REAL ID-compliant driver's licenses. These licenses have a gold star in the upper right corner of the front side. A REAL ID license meets federal standards for identification and can be used for domestic air travel and entry to federal buildings without a passport.
If your license does not have a gold star, it is still a valid Arizona driver's license for driving purposes, but you cannot use it alone for domestic air travel or federal building access — you would need a passport or other federal ID. When you renew your license, you can request a REAL ID-compliant card by providing proof of citizenship and residency at the time of renewal.
Frequently Asked Questions
What do the numbers on the back of my license mean?
The numbers on the back are part of the machine-readable zone and barcode. They encode your personal information, license number, and status in a format that scanners can read. You do not need to memorize or interpret these numbers yourself — they are for automated systems used by law enforcement and authorized businesses.
Can I have multiple endorsements on one license?
Yes. You can hold multiple endorsements on a single license if you pass the tests for each one. For example, you could have both an M (motorcycle) and an H (hazmat) endorsement. Each endorsement requires its own separate test and fee.
What happens if I drive with an expired license?
Driving with an expired license is a traffic violation in Arizona. You may receive a citation and fine. If you are stopped, you should show proof that you have applied for renewal. Some officers may issue a warning if your renewal is pending, but this is not may provide.
Does my license number change if I get a replacement card?
No. If you lose your license or request a replacement due to damage, your eight-digit license number remains the same. Only the card itself is replaced. Your driving record and history stay attached to the same number.
Why does my license have a restriction I do not think I need anymore?
Restrictions are typically added based on your medical history, vision test results, or the circumstances of your original license issuance. If you believe a restriction no longer applies — for example, if you have had corrective eye surgery — you can contact the Arizona Department of Transportation to request a vision retest or hearing to have the restriction removed.
