Your identification number is printed in the upper right corner of your driver's license, below your photo

The identification number (also called the driver's license number or DL number) is a unique code assigned to you by your state's DMV. It appears as a series of numbers and sometimes letters, and its exact location and format depend on which state issued your license. On most modern licenses, you will find it in the upper right area of the card, positioned below or beside your photograph. Some states print it in the lower right corner instead.

This number is not the same as your Social Security number, date of birth, or any other identifier. It is specific to your driver's license and changes if you renew your license in a different state or if your state reissues licenses with a new format. You will need this number when you renew your license, report it lost or stolen, check your driving record, or provide proof of identity to insurance companies, law enforcement, or government agencies.

Key Takeaways

  • Your driver's license identification number is printed on the front of your card, usually in the upper right corner below your photo, though some states place it in the lower right.
  • The format varies by state — some use only numbers, while others mix numbers and letters — and the length typically ranges from 4 to 13 characters.
  • This number is unique to your license and changes when you renew or move to a different state, so it is different from your Social Security number.
  • You will need your identification number to renew your license, report it lost or stolen, check your driving record, and provide proof of identity to insurance companies and government offices.

How identification numbers are formatted by state

Each state designs its own identification number system, so the format you see depends on where your license was issued. Some states use a straightforward numeric sequence — for example, a 7-digit or 8-digit number. Others combine numbers with letters based on your name, birth date, or other personal information. A few states embed your date of birth or initials into the number itself, while others use a completely random sequence.

The length also varies. Florida uses 6 digits, California uses 8 digits, New York uses a combination of letters and numbers that can be up to 19 characters long, and Texas uses 8 digits. If you move to a new state and get a license there, your new state will assign you a completely different identification number in its own format. Your old number does not transfer, and the new state's DMV will not reference it.

Because formats differ so widely, there is no single rule for what your number should look like. If you are unsure whether you are reading the correct number on your license, compare it to the number printed on your renewal notice, insurance documents, or your state's DMV website — these sources will show you exactly which number belongs to your license.

Where to locate it on different license designs

Most states print the identification number on the front of the license card, but the exact position varies. The most common placement is the upper right corner, below your photograph. Some licenses print it to the right of your photo, and a smaller number of states place it in the lower right corner or along the bottom edge of the card.

Vertical licenses (which are taller than they are wide, typically issued to drivers under 21) often have the identification number in a different spot than horizontal licenses (standard adult licenses). If you have a vertical license and later renew it as a horizontal license, the number position will change, though the number itself may remain the same depending on your state's renewal rules.

If you cannot find the number on your physical card, check your renewal notice, your state's DMV website, or your insurance documents. All of these sources print your identification number clearly and can help you confirm which number is correct.

Why you need your identification number and when to use it

Your identification number serves as your unique identifier within your state's DMV system. You will need it to renew your license online or by mail, to check your driving record, to report your license lost or stolen, and to request a replacement card. Insurance companies ask for it when you get a quote or file a claim. Law enforcement may request it during a traffic stop. Government agencies and financial institutions may ask for it as a form of identification.

When you renew your license, the DMV uses your identification number to pull up your existing record and confirm your personal information. If you are renewing online or by mail, you will usually enter this number to verify your identity. If you lose your license and need a replacement, you will provide this number to the DMV so they can reissue your card with the same number (in most states).

Keep your identification number in a safe place separate from your physical license. If your license is lost or stolen, you can report it to the DMV using your identification number, even if you do not have the card in front of you. This number is also useful if you need to check your driving record online — most states' DMV websites let you look up your record by entering your identification number and date of birth.

What to do if you cannot find your identification number

If your license is damaged, faded, or old and the number is no longer legible, contact your state's DMV directly. You can usually call the DMV customer service line and provide your name and date of birth, and they will tell you your identification number. Many states also let you look up this information on their DMV website by entering your name, date of birth, and address.

If you have lost your physical license but remember your identification number, write it down or save it in a find location. You can use it to request a replacement license without having the card present. If you have lost both your card and your number, the DMV can still help you — they will verify your identity using your name, date of birth, and address, then provide you with your identification number and issue a replacement license.

Some states print your identification number on your renewal notice, vehicle registration documents, or insurance cards. Check these documents first before contacting the DMV. If you have an old license from a previous renewal, that card will show your old identification number, which may help you locate your current number in the DMV system.

Identification number versus other numbers on your license

Your driver's license contains several different numbers, and it is important to know which one is your identification number. Your date of birth appears on the license but is not your identification number. Your Social Security number does not appear on your license at all (though the DMV uses it internally to verify your identity). Your license class or type (such as "D" for regular driver or "CDL" for commercial) is a letter or code, not your identification number.

Some states print a control number or document number on the back of the license — this is different from your identification number and is used to verify the authenticity of the card itself. The identification number is always on the front of the card and is the number you will use most often when dealing with the DMV, insurance companies, or other agencies.

If you are unsure which number is which, look at your renewal notice or your state's DMV website — these sources label each number clearly so you can tell them apart.

Frequently Asked Questions

Does my identification number change when I renew my license?

In most states, your identification number stays the same when you renew your license. However, if you move to a new state and get a license there, you will receive a completely new identification number in that state's format. Some states may also issue a new number if you request a replacement card due to damage or loss, though many will keep your original number.

Can I use my identification number instead of my Social Security number?

No. Your identification number and Social Security number are separate. Some agencies may ask for your identification number as proof of a valid driver's license, but they will ask for your Social Security number separately if they need it. Never assume one can substitute for the other.

Is my identification number the same as my license plate number?

No. Your license plate number is printed on your vehicle registration and identifies your car. Your identification number is printed on your driver's license and identifies you as a driver. They are completely different numbers used for different purposes.

What should I do if someone asks for my identification number?

It is generally safe to provide your identification number to the DMV, your insurance company, law enforcement, or government agencies that have a legitimate reason to ask for it. Be cautious about giving it to private businesses or individuals unless you have a clear reason to trust them and understand why they need it.

Can I look up my identification number online?

Most states allow you to look up your identification number on their DMV website by entering your name, date of birth, and address. Some states require you to create an online account first. If your state does not offer this service, you can call the DMV customer service line and provide your personal information to get your number.
