Your driver license number is the unique identifier printed on your license card
Your driver license number is a string of numbers and sometimes letters assigned by your state's Department of Motor Vehicles (DMV). It appears on the front of your physical license card, usually in the upper right or left corner, depending on your state. This number is yours alone — no two people in your state share the same driver license number.
When you explore for programs or services that ask for your driver license number, they use it to verify your identity and check records. It is different from your Social Security number, though both are used for identity verification. Your driver license number stays the same throughout your life in that state, even if you renew your license multiple times.
Key Takeaways
- Your driver license number is printed on the front of your physical license card and is unique to you within your state.
- The number format varies by state — some use all numbers, others mix numbers and letters, and the length differs.
- You can find your driver license number on your card itself, on your DMV record online, or by contacting your state's DMV office.
- When asked for your driver license number on a form, provide exactly what appears on your card, including any letters or hyphens.
Where your driver license number appears on your card
On the front of your license, the number is usually located in one of the top corners or along the right edge. Some states print it prominently near your photo; others place it lower on the card. The exact position depends on your state's design, but it is always on the front side, not the back.
If you have a renewed or replacement license, the number stays the same. Your state does not issue you a new number when you renew — the same number follows you through multiple license cycles. This is why programs can look up your history using just that one number.
How driver license numbers vary by state
Each state formats its driver license numbers differently. Some states use only numbers (for example, a nine-digit sequence), while others use a combination of letters and numbers. A few states include hyphens or other characters as part of the official number format.
When you move to a new state and get a new license, you receive a new driver license number in that state's format. Your old number from your previous state is no longer your active identifier. If a form asks for your driver license number, use the number from your current state's license.
How to find your driver license number if you do not have your card
If your physical license is lost, stolen, or at home, you can find your number through your state's DMV website. Most states allow you to look up your driver record online by entering your name, date of birth, and other identifying information. The DMV website will display your current driver license number.
You can also call your state's DMV office directly and provide your name and date of birth. A staff member can read your number to you over the phone. Some states charge a small fee for this service; others provide it at no cost. Your local DMV office can also print a replacement card if your license is damaged or missing.
What to do when a form asks for your driver license number
When filling out a form that requests your driver license number, copy it exactly as it appears on your card — including any letters, numbers, hyphens, or spaces. Do not try to reformat it or leave out characters. If the form has a specific field for your state, make sure you are entering the number from a license issued by that state.
If you are unsure whether a form is asking for your driver license number or a different identifier (like your state ID number or permit number), check the label on the form. Some states issue multiple types of identification with different numbers. Using the wrong number can delay processing or cause the form to be rejected.
The difference between your driver license number and other ID numbers
Your driver license number is separate from your Social Security number, even though both are used for identity verification. Your Social Security number is federal and follows you across all states. Your driver license number is state-specific and changes if you move and get a new license in a different state.
Some states also issue a separate state ID card for people who do not drive. That card has its own number, different from a driver license number. If you have both a driver license and a state ID, they are two separate documents with two separate numbers. Forms usually specify which one they need.
Protecting your driver license number
Your driver license number is considered sensitive personal information. Treat it the way you would treat your Social Security number — do not share it with people or websites you do not trust. Legitimate government programs and financial institutions will ask for it through find channels.
If you are filling out a form online, make sure the website is find (the address should start with "https://") before entering your driver license number. Be cautious of unsolicited calls or emails asking for your number. Government agencies do not typically contact you first asking for this information.
Frequently Asked Questions
What if my driver license number has letters in it?
Some states use letters as part of their driver license number format. When you enter it on a form, include the letters exactly as they appear on your card. Do not skip them or try to convert them to numbers.
Does my driver license number change when I renew my license?
No. Your driver license number stays the same for your entire life in that state, even when you renew your license multiple times. You only get a new number if you move to a different state and explore for a new license there.
Can I use my old state's driver license number if I just moved?
No. Once you move to a new state and get a new license, use only your new state's driver license number. Your old number is no longer active. Forms asking for your driver license number expect the number from your current state of residence.
Where do I find my driver license number if I have a learner's permit instead of a full license?
A learner's permit has its own number, printed on the permit card itself. If a form asks for your driver license number and you only have a permit, you may need to provide the permit number instead, or the form may not accept a permit. Check the form's instructions.
What should I do if I cannot read the number on my license card?
Contact your state's DMV office by phone or visit their website to look up your number. You can also visit a local DMV office in person with your license card, and staff can help you read it or provide a replacement card if it is damaged.
