Your DMV identification number is a unique code your state assigns when you get a driver's license or ID card

Every state's Department of Motor Vehicles issues a separate identification number for each person who holds a license or ID. This number appears on your physical card and in the DMV's database. It is not the same as your driver's license number — though they are often printed on the same card, they serve different purposes in the system.

The DMV identification number stays with your record even if you renew your license, move to a new address, or change your name. You will need it when you renew, replace a lost card, check your driving record, or handle certain vehicle transactions. Some states call it a "customer ID" or "document number" rather than an identification number, but the function is the same.

Key Takeaways

  • Your DMV identification number is printed on your driver's license or ID card and is different from your license number itself.
  • The number stays the same throughout your life in that state, even if you renew your license or change your address.
  • You can find your DMV ID number on your physical card, through your state's online DMV portal, or by calling your local DMV office.
  • You will need this number to renew your license, request a duplicate card, check your driving record, or handle title and registration matters.

Where to find your DMV identification number

The fastest way is to look at your current driver's license or ID card. Most states print the identification number on the front or back of the card, usually near your name or license number. The exact location varies by state — some place it in the upper right corner, others along the bottom edge. If your card is damaged or you cannot read the number clearly, you have other options.

Your state's DMV website usually has a portal where you can log in with your license number and date of birth to view your record, which includes your identification number. You can also call your local DMV office directly and provide your name and date of birth; staff can look up the number in seconds. A few states allow you to request this information by mail, though it takes longer.

How your DMV identification number differs from your license number

Your driver's license number is the main identifier on your card — it is what police officers check during traffic stops and what appears on your driving record. Your DMV identification number is an internal reference code that the motor vehicle department uses to track your account and link all your records together.

Think of it this way: your license number is what the public-facing system uses, while your identification number is what the DMV's internal database uses. If you renew your license in most states, your license number changes, but your identification number does not. This allows the DMV to maintain a continuous history of your driving record, vehicle registrations, and any violations or suspensions, even as your license number changes over time.

When you will need your DMV identification number

You will need it most often when renewing your license or ID card, especially if you are doing so online or by mail. Many states require the identification number to confirm your identity before processing a renewal. If you need to request a duplicate or replacement card because yours was lost or stolen, the DMV will ask for this number to pull up your record quickly.

Vehicle-related transactions also require it. If you are registering a vehicle, transferring a title, or updating your address on your registration, the DMV may ask for your identification number to link the transaction to your account. Some states also require it when you check your driving record online or request an official copy of your record for insurance or employment purposes.

What to do if you cannot find your identification number

Do not assume you need it before you contact the DMV. Many transactions can proceed with just your name, date of birth, and license number. Call your local DMV office and explain what you are trying to do — staff can often look up your identification number on the spot and provide it over the phone, or they can complete the transaction without you having to provide it yourself.

If you are renewing online and the system asks for your identification number but you do not have it, most state portals have a "forgot your ID number" link that will let you verify your identity another way. You may be asked to answer security questions, provide your Social Security number, or confirm recent addresses. Once verified, the system will display your identification number and let you proceed.

Keeping your identification number find

Your DMV identification number is not as sensitive as your Social Security number, but it is still part of your identity record. Do not share it casually or post it online. If someone asks for it, confirm they are actually from your state's DMV before providing it — scammers sometimes pose as DMV staff to collect personal information.

When you receive documents from the DMV that show your identification number, store them safely. If your license is lost or stolen, report it to the DMV right away so they can flag your account. This does not change your identification number, but it does alert the system that your card is no longer valid.

Frequently Asked Questions

Is my DMV identification number the same in every state?

No. Each state maintains its own DMV database and assigns its own identification numbers. If you move to a new state and get a new license there, you will receive a new identification number from that state's DMV. Your old number from your previous state remains in that state's records only.

Can I change my DMV identification number?

No. Your identification number is assigned by the DMV and cannot be changed. It is tied to your record permanently. If you renew your license, your identification number stays the same — only your license number may change, depending on your state's renewal process.

What if I lost my license and do not remember my identification number?

You do not need to remember it. When you explore for a replacement license, provide your name, date of birth, and address. The DMV will look up your record using that information and process your replacement. You can ask them to tell you your identification number at that time.

Do I need my DMV identification number to renew my license online?

Most states ask for it during online renewal to verify your identity, but not all. If the online system asks for it and you do not have it, look for a "forgot your ID" option or call the DMV. Many states will let you complete renewal by phone or mail if the online system does not work for you.
