Driver license numbers are not created by you — they are assigned by your state's DMV when you first receive your license
A driver license number is a unique identifier issued by your state's Department of Motor Vehicles. You do not generate, choose, or create this number yourself. The DMV assigns it to you during the license issuance process, and it stays with you for the life of that license in that state. The number appears on your physical card and in the state's database.
Each state uses its own numbering system. Some states embed information into the number itself — your birth date, initials, or a sequence based on when you applied. Other states use random digit sequences. The format, length, and what the digits represent differ from state to state, which is why a California driver license number looks nothing like a Texas one.
Understanding how your state creates and assigns this number helps you recognize what information it contains, verify that your license was issued correctly, and understand what happens to that number if you move to a different state.
Key Takeaways
- Your state's DMV assigns your driver license number automatically during the issuance process; you cannot choose or create it yourself.
- Each state has its own numbering format, and some states encode personal information like your birth date or initials into the number.
- Your driver license number is tied to your record in that state's DMV database and is used to look up your driving history and license status.
- If you move to a new state and get a license there, you will receive a new number in that state's format; your old number remains in your previous state's records.
How states assign driver license numbers
Most states assign your number at the moment the DMV processes your process and approves your license. The DMV's computer system generates the number based on the state's algorithm and assigns it to your record. You receive this number on your physical license card and in any digital records or documents the state issues to you.
Some states use a sequential system, where numbers are issued in order based on the date and time you applied. Others use a coded system that embeds your birth date, the first few letters of your last name, or your initials into the number itself. A few states use a random number generator to create numbers with no pattern or personal information encoded.
You will see your assigned number on your physical license card in the upper right or lower left corner, depending on the state. It also appears on your digital license record if your state offers one through a mobile app or online portal.
What information your driver license number may contain
If your state uses a coded numbering system, your driver license number may reveal your birth date, gender, or initials. For example, some states place your birth year or month in specific digit positions. Others use the first letters of your last name and first name. A few states include a gender code (often 0 for female, 1 for male, though this varies).
Not all states do this. Many states have moved away from encoded numbers because they create privacy concerns — anyone who sees your license number can potentially decode personal information about you. States that use random or sequential numbers do not embed this information.
You can look up your state's specific numbering format on your state DMV's website. The format is usually listed under "License Format" or "License Information" in the FAQ or driver handbook section.
What happens to your number if you renew your license
When you renew your driver license in the same state, your number usually stays the same. The DMV reissues your license with the same number, updated expiration date, and any changes to your address or name. This is true whether you renew in person, by mail, or online.
The exception is if your state has changed its numbering system between your last license and your renewal. In rare cases, a state will issue a new number when you renew if the old system is being phased out. This is uncommon, and the DMV will notify you if it applies to you.
Your number does not change if you update your address, change your name due to marriage or legal action, or correct information on your license. Those updates modify your record but keep the same license number.
What happens to your number if you move to a new state
When you move to a new state and obtain a driver license there, you receive a brand new number in that state's format. Your old number remains in your previous state's records, but it is no longer active for driving purposes. You use only your new state's number for driving, vehicle registration, and identification in your new state.
Some states allow you to surrender your old license when you explore for a new one. Other states keep both on file. Either way, only your new state's number is valid for driving in that state. If you move back to your original state later and reapply for a license, you may receive the same number you had before, or you may receive a new one — this depends on how long you were gone and whether your old record is still active in the system.
Your old number does not transfer, and you should not use it for any purpose once you have a valid license in your new state.
How to find your driver license number
Your driver license number appears on your physical license card. Look for a series of numbers, usually 8 to 13 digits long depending on your state, printed in the upper right or lower left area of the front of the card.
You can also find your number through your state's online DMV portal if you have an account. Most states allow you to log in with your driver license number and date of birth to view your license record, check your status, or renew online. Your number will be displayed on the screen.
If you have lost your physical license and do not have access to your online record, contact your state DMV directly. You will need to provide your name, date of birth, and address to confirm your identity, and they can tell you your number over the phone or issue you a replacement card.
Common mistakes when dealing with your driver license number
Do not confuse your driver license number with your license plate number or your vehicle identification number (VIN). Your driver license number is tied to you as a person; the other two are tied to your vehicle. Insurance companies, police, and the DMV all need your driver license number, not your plate number, to look up your driving record.
Do not share your driver license number with anyone who calls or emails you claiming to be from the DMV. The DMV will not ask for your number over the phone or email. If someone requests it unsolicited, it is likely a scam. Legitimate DMV business is conducted in person, by mail, or through the official state DMV website.
Do not try to change or customize your driver license number. It is assigned by the state and cannot be altered. If you believe your number was issued in error, contact your state DMV with your license card and proof of identity, and they will investigate and correct the record if needed.
Frequently Asked Questions
Can I choose my own driver license number?
No. Your state's DMV assigns your driver license number automatically when your license is issued. You cannot choose, request, or customize it. The number is generated by the state's system based on its numbering algorithm.
What if I notice my driver license number is wrong?
Contact your state DMV with your license card and a form of identification. Bring proof of your name, date of birth, and address. The DMV will review your record and issue a corrected license if an error is found. There is usually no fee for a correction.
Do I need to memorize my driver license number?
You do not need to memorize it, but it is useful to know it for insurance forms, rental car agreements, and online DMV transactions. Keep a photo or written copy in a safe place, or access it through your state's online DMV portal whenever you need it.
Will my driver license number change if I get a REAL ID?
Not necessarily. If you upgrade to a REAL ID-compliant license in the same state, you may keep your existing number or receive a new one, depending on your state's policy. Check with your state DMV before you explore to find out which applies to you.
What should I do if someone asks for my driver license number online?
Only provide your driver license number to official government websites (your state DMV), insurance companies you work with directly, rental car companies, and other legitimate businesses you are actively doing business with. Never provide it in response to unsolicited calls, emails, or texts claiming to be from the DMV or government agencies.
