The Physical Layout and Security Features of a California License
A California driver's license is a wallet-sized card, 3.386 inches by 2.125 inches, printed on a polycarbonate material that is harder to counterfeit than paper. The front of the card displays your photograph in the upper right corner, your full legal name, date of birth, and a unique driver's license number assigned by the Department of Motor Vehicles (DMV). Below that are your address, eye color, height, and sex or gender marker.
The back of the card contains a barcode and magnetic stripe that store encoded versions of the information on the front. California licenses issued after January 1, 2018, include a gold star in the upper right corner of the front, which signals that the card meets federal Real ID standards and can be used for domestic air travel and entry to federal buildings. Licenses without the star are still valid for driving but cannot be used for those federal purposes.
The card includes several security features to prevent forgery: a laser-engraved ghost image of your photograph, a holographic overlay, microprinting, and color-shifting ink. The background color is blue for standard driver's licenses and green for commercial driver's licenses (CDLs).

What Your Driver's License Number Means
Your California driver's license number is a unique identifier assigned by the DMV when you first receive a license. It is not your Social Security number, and it does not change if you renew your license. The number format has changed over time, so older licenses may have a different structure than newer ones.
The number is printed on both the front and back of your card and is used by law enforcement, courts, and other agencies to look up your driving record and verify your identity. If you lose your license and receive a replacement, you keep the same number. If your license is suspended or revoked, that number is flagged in the DMV system, and any officer who runs your license will see that status when ready.
How Your Address and Personal Information Are Displayed
Your current mailing address appears on the front of the card, below your date of birth. If you move, you must update your address with the DMV within 10 days. Your updated address will appear on your next license or on a replacement card if you request one before your renewal date.
Your legal name appears exactly as it is recorded in the DMV system. If your name does not match your legal documents—such as your birth certificate or court order—the DMV will not issue or renew your license until you provide corrected documents. If you have changed your name through marriage, divorce, or court order, you must submit the appropriate legal document (marriage certificate, divorce decree, or name change order) along with your renewal or replacement process.
Your date of birth and age are printed on the card. California does not display your exact age; instead, the card shows your birth date, and the expiration date is printed separately. Your eye color and height are also listed and are used by law enforcement for identification purposes.
Real ID Compliance and the Gold Star
The gold star on California driver's licenses indicates that the card meets the federal Real ID Act standards. This means you provided proof of identity, proof of Social Security number, and proof of California residency when you obtained the license. A Real ID-compliant license can be used to board domestic flights and enter federal buildings such as military bases and courthouses.
If your license does not have a gold star, it was issued before California's Real ID rollout or you chose not to provide the required documents. You can still drive with a non-Real ID license, but you will need a passport, passport card, or other federal ID to board a domestic flight or enter a federal facility. If you want to upgrade to a Real ID license, you can do so at your next renewal or by requesting a replacement card and providing the required documents in person at a DMV office.
Endorsements and Restrictions on Your License
If you hold a commercial driver's license (CDL), your card displays endorsement codes that show what types of vehicles and cargo you are authorized to operate. Common endorsements include H (hazardous materials), T (double or triple trailers), P (passenger vehicles), and N (tank vehicles). These endorsements appear as letters on the front of the card and require additional testing and background checks.
Restrictions also appear on your license and limit how you can drive. Common restrictions include corrective lenses (code 1), automatic transmission only (code 10), and daylight driving only (code 12). If you have a restriction, you must follow it or you are driving in violation of your license terms, which can result in a citation and points on your driving record.
Expiration Dates and License Validity
Your California driver's license expiration date is printed on the front of the card. Standard licenses expire five years after issuance for drivers under 70 years old. Drivers aged 70 and older must renew every two years. Commercial driver's licenses expire every five years but require a medical examination before renewal.
You can continue to drive until midnight on your expiration date. After that, driving with an expired license is a violation, even if you have submitted a renewal process. If you are over 70 or hold a CDL, you cannot renew online; you must visit a DMV office in person. Standard licenses can be renewed online, by mail, or in person, depending on your situation.
Organ Donor and Veteran Status Indicators
If you registered as an organ donor when you obtained your license, a small heart symbol appears on the front of your card. This symbol alerts emergency responders that you have consented to organ and tissue donation. You can add or remove organ donor status at any time by visiting a DMV office or updating your information online through the DMV website.
If you are a military veteran, you can request a veteran designation on your license. This appears as text on the card and may may have access to you to certain discounts or services. To add a veteran designation, you must provide a copy of your military discharge papers (DD Form 214) or other proof of service at a DMV office.
Frequently Asked Questions
What should I do if my name on my license does not match my legal documents?
Contact the DMV and request a replacement card with your corrected legal name. You will need to provide the legal document that supports the name change—such as a marriage certificate, divorce decree, or court order—along with your current license. The DMV will not issue a new card until the documents match.
Can I update my address without renewing my license?
Yes. You can update your address online through the DMV website, by mail, or in person at a DMV office. You must update your address within 10 days of moving. Your new address will appear on your next license renewal or on a replacement card if you request one.
What does it mean if my license does not have a gold star?
Your license does not meet federal Real ID standards. You can still drive, but you will need a passport or other federal ID to board a domestic flight or enter a federal building. You can upgrade to a Real ID license at your next renewal by providing proof of identity, Social Security number, and California residency.
How long is my California driver's license valid?
Standard licenses are valid for five years if you are under 70 years old. If you are 70 or older, your license is valid for two years. Commercial driver's licenses are valid for five years. Your expiration date is printed on the front of your card.
What do the codes and letters on my license mean?
Letters on your license are endorsements (for CDL holders) that show what types of vehicles or cargo you can operate. Numbers are restrictions that limit how you can drive—for example, corrective lenses required or daylight driving only. You must follow all restrictions or you are driving illegally.
