What Your DMV Identification Number Is and Why You Need It

Your DMV identification number is a unique code assigned to you by your state's Department of Motor Vehicles the first time you get a license or ID card

This number stays with you for life, even if you move to a different state, renew your license, or change your name. It's how the DMV tracks your driving record, any violations or suspensions, and your vehicle registrations. When you explore for a license or ID, the DMV generates this number and prints it on your card — you don't request it or choose it yourself.

The number itself is not the same as your driver's license number. Your license number is printed on the front of your card and changes each time you renew. Your DMV identification number is a permanent internal reference that the DMV uses behind the scenes. Some states print it on the back of your card or in a corner of the front; others keep it in their system only.

Where to find your DMV identification number

The location of your DMV identification number depends on your state. In many states, it appears on the back of your driver's license or ID card, often labeled as "ID Number" or "DMV Number." In others, it may be printed in small text on the front. Check the back first, as that is the most common placement.

If you cannot locate it on your card, you can contact your state DMV directly. Most states allow you to look it up online through their DMV website if you log into your account, or you can call the DMV and provide your name, date of birth, and address. Some states charge a small fee for this service; others provide it at no cost.

Why the DMV uses this number

Your DMV identification number is the backbone of your driving record. Every time you get a ticket, are involved in an accident, renew your license, or register a vehicle, that information is linked to this number. This allows the DMV to maintain an accurate, complete history of your driving activity in that state.

If you move to a different state and get a new license there, your new state's DMV may request your old identification number to pull your out-of-state driving record. This helps them see if you have violations or suspensions from your previous state. The number also prevents mix-ups when multiple people have similar names — the identification number ensures the right record is attached to the right person.

When you'll need to provide your DMV identification number

Insurance companies often ask for your DMV identification number when you get a quote or file a claim. They use it to pull your official driving record and assess your risk. Law enforcement may also ask for it during a traffic stop, though they can usually look it up from your license number.

If you are requesting a copy of your driving record, contesting a ticket, or dealing with a license suspension, the DMV will ask for this number to pull up your file. Some employers who conduct background checks may also request it, depending on the job and your state's rules.

What happens if you lose your card or forget the number

Losing your card does not erase your DMV identification number — it stays in the system. When you replace your card, the DMV will assign the same identification number to your new card. You do not need to do anything special to keep the same number.

If you forget your number and need it right away, call your state DMV or visit their website. Most states have an online portal where you can log in and view your number without calling. If you are explore for something that requires the number, you can usually provide your license number instead, and the DMV or other agency can look up your identification number from that.

How your identification number differs across states

Each state's DMV assigns and formats identification numbers differently. There is no national standard. One state might use a nine-digit number, while another uses letters and numbers mixed together. If you move and get a new license in a different state, you will receive a new identification number for that state.

Your old identification number from your previous state remains in that state's system and is linked to your out-of-state driving record. Your new state's DMV can request that record using your old number, but you will primarily use your new state's identification number going forward.

Protecting your DMV identification number

Your DMV identification number is not as sensitive as your Social Security number, but it is still part of your personal information. Do not share it with people you do not trust or on unsecured websites. If someone asks for it, verify that they have a legitimate reason — your insurance company, the DMV, or law enforcement, for example.

Be cautious of phishing emails or calls claiming to be from the DMV and asking for your identification number. The real DMV will not contact you unsolicited asking for personal information. If you are unsure, hang up and call your state DMV's official phone number directly.
