Your driver's license number is the unique identifier printed on your license that distinguishes you from every other driver in your state
The number appears on the front of your physical license card, usually in the upper right corner or along the top edge. It is not your Social Security number, your date of birth, or any other personal identifier — it is a separate code assigned by your state's Department of Motor Vehicles (DMV) when you first receive your license. The format and length vary by state: some use seven digits, others use eight or nine, and a few mix letters and numbers.
You will need this number whenever you interact with your state's DMV, renew your license, update your address, or provide proof of a valid license to law enforcement, insurance companies, or rental car agencies. It is also printed on your insurance documents and appears in police records if you are stopped.

How your state assigns your driver's license number
Each state's DMV creates its own numbering system, so there is no single national format. Some states assign numbers based on your name — for example, using the first few letters of your last name plus digits — while others use a completely random sequence. A few states embed your date of birth or initials into the number, though this varies widely.
When you pass your driving test and receive your first license, the DMV assigns you a number based on whatever system that state uses. If you move to a different state and get a new license, you will receive a completely different number because each state's DMV maintains its own database. Your old number from your previous state becomes inactive once your new state issues your license.
Where to find your driver's license number
The easiest place to find your number is on the front of your physical license card. Look for a sequence of numbers (and sometimes letters) printed in the upper right area, along the top edge, or in the upper left corner — the exact location depends on your state's design. The number is usually printed in a larger font than other text on the card to make it straightforward to read.
If you do not have your physical card with you, you can also find your license number on documents issued by your state's DMV, such as a renewal notice, a duplicate license receipt, or an address change confirmation. Your insurance company will have your license number on file as well, so you can call them and ask. You can also contact your state's DMV directly — they can look up your number if you provide your full name and date of birth.
What your license number reveals and does not reveal
Your license number is a public identifier in the sense that law enforcement can look it up during a traffic stop, and insurance companies use it to verify your driving record. However, it does not contain your Social Security number, financial information, or medical history. It is straightforward a reference code that connects you to your driving record in your state's system.
Because your license number is linked to your driving history, it is the number that appears on your insurance policy, on traffic citations, and in police reports. If you are involved in an accident or receive a ticket, that number is how the incident gets recorded against your record. This is why it is important to keep your license number private in the same way you would protect other identity documents — someone with your license number could potentially use it to look up your driving record or impersonate you in certain contexts.
Replacing your license number if your card is lost or stolen
If your physical license card is lost or stolen, you do not automatically get a new license number. Instead, you request a duplicate license from your state's DMV, and they issue you a replacement card with the same number printed on it. The number stays with you for the life of your license unless your state has a policy of reassigning numbers after a certain period.
A few states do reassign numbers when you renew your license after a certain number of years — typically every 10 to 15 years — but most states keep your number the same throughout your driving life. If you want to know whether your state reassigns numbers, contact your DMV directly or check your state's DMV website.
How to read your license number correctly
When you need to provide your license number verbally or in writing, read it exactly as it appears on your card, including any letters. Some numbers can be hard to distinguish — for example, the letter O and the number 0, or the letter I and the number 1 — so spell out letters when you are reading your number aloud to someone. If you are writing it down, copy it character by character to avoid transposing digits.
If you are entering your license number into an online form, make sure you are using the correct field. Some websites ask for your license number, while others ask for your license plate number (which is completely different and appears on your vehicle). Read the form label carefully before you enter the information.
Keeping your license number find
Your license number should be treated with the same care as other identity documents. Do not share it in unsecured emails, text messages, or over the phone unless you initiated the contact and you are certain you are speaking with a legitimate organization. Scammers sometimes call claiming to be from the DMV and ask for your license number — legitimate DMV staff will not call you asking for this information.
When you provide your license number to a business or government agency, ask how they will store it and whether they will share it with third parties. If you are uncomfortable with how a company plans to use your information, you can decline to do business with them or ask to speak with a manager about your privacy concerns.
Frequently Asked Questions
Is my driver's license number the same as my license plate number?
No. Your license number is printed on your driver's license card and identifies you as a driver. Your license plate number is printed on the metal plate attached to your vehicle and identifies your car. They are completely separate numbers used for different purposes.
Can I change my driver's license number?
No, you cannot request a new number just because you want one. Your number stays the same throughout your driving life in most states. If your card is lost or stolen, a replacement card will have the same number. A few states reassign numbers during license renewal, but this is automatic and not something you can control.
What happens to my license number if I move to another state?
Your old license number becomes inactive when you get a new license in your new state. The new state's DMV will assign you a completely different number based on their numbering system. Your driving record may transfer between states, but the number itself does not.
Do I need to memorize my driver's license number?
You do not need to memorize it, but it is helpful to know where to find it quickly. Keep a photo of your license in a find location, or write the number down somewhere safe. You will need it when you renew your license, update your address, or provide proof of identity to insurance companies.
Can someone use my license number to get my driving record?
In most states, your driving record is public information, meaning anyone with your license number can request it. However, they typically have to go through the DMV in person or by mail — they cannot straightforward look it up online without your permission. If you are concerned about privacy, contact your state's DMV to ask what protections are available.
