Your driver's license holds multiple identification numbers in different places
Your driver's license contains several numbers, but the one most often called your "government issued identification number" is your driver's license number — the unique code your state's Department of Motor Vehicles assigned to you. On most licenses, this appears in the upper right area of the front, though the exact position varies by state. Some states also print a second number on the back. You may also see your Social Security number printed on the license itself, depending on your state's policy.
The confusion arises because "government issued identification number" can refer to different things depending on the context. When you're filling out a form that asks for this number, the instructions usually clarify which one they want — but if they don't, the driver's license number is the safest choice, since it's the identifier most directly tied to your license itself.
Key Takeaways
- Your driver's license number is printed on the front of your license, typically in the upper right corner, and is the primary government ID number associated with your license.
- The exact location and format of the license number varies by state, so check your specific state's license layout if you're having trouble locating it.
- Some states also print your Social Security number on the back of your license, which is another form of government identification but not the same as your license number.
- When a form asks for your "government issued identification number" without specifying which one, your driver's license number is usually what they're requesting.
How to locate your driver's license number on the front
The front of your license is where you'll find the driver's license number in nearly all states. Look in the upper right portion of the card — you should see a string of numbers and sometimes letters. This is your unique license number. The format differs by state: some use all numbers, others mix numbers and letters, and the length varies from around 5 digits to 13 or more.
If the upper right area doesn't show a number, scan the entire front of the card. A few states position this number elsewhere on the front — for example, some place it below your photograph or along the left edge. Your state's DMV website can show you exactly where to look on your specific license design.
What to check on the back of your license
The back of your license may contain additional identification information. Some states print a second copy of your driver's license number on the back for convenience. Others print your Social Security number on the back instead of (or in addition to) the front. A handful of states include both numbers on the back only.
The back also typically shows your address, any restrictions or endorsements on your license, and organ donor status. If you're looking for a specific number and can't find it on the front, the back is the next place to check.
Understanding the difference between your license number and Social Security number
Your driver's license number and your Social Security number are two separate government identifiers. Your Social Security number is a nine-digit code assigned by the federal government and used for tax, employment, and benefits purposes. Your driver's license number is assigned by your state and is specific to your driving record and vehicle registration.
Many states have moved away from printing Social Security numbers on driver's licenses due to privacy concerns. If your license does show your Social Security number, treat that side of the card carefully — don't photograph it or share images of it online. When a form asks for your "government issued identification number," they usually mean your license number unless they specifically ask for your Social Security number.
Why different forms ask for different numbers
Government agencies, financial institutions, and other organizations request identification numbers for different reasons. Your driver's license number is used when the organization needs to verify your identity through your driving record or state records. Your Social Security number is used for tax purposes, credit checks, and federal benefit programs.
If a form doesn't specify which number to provide, read the instructions carefully or contact the organization directly. Providing the wrong number can delay processing, though it's usually not a serious problem — the organization will straightforward ask you to clarify.
What to do if you can't find your license number
If your license is damaged, faded, or you straightforward can't locate the number, your state's DMV can provide it. You can call your state's DMV customer service line, visit a local DMV office in person, or check your DMV account online if your state offers one. Have your name, date of birth, and address ready when you contact them.
You can also find your license number on documents you've received from your state — your original license process confirmation, vehicle registration paperwork, or insurance documents often list your license number. If you've had a ticket or been pulled over, the citation will show your license number as well.
Frequently Asked Questions
Is my driver's license number the same as my identification number?
Your driver's license number is a form of government-issued identification number, but "identification number" can refer to several different codes. If a form asks for your "identification number" without specifying, it usually means your driver's license number if you're providing a driver's license as your ID. If you're using a different form of ID, use the number from that document.
Can I use my Social Security number instead of my license number?
Not usually. If a form specifically asks for your driver's license number, providing your Social Security number instead will likely cause the request to be rejected or delayed. The two numbers serve different purposes in government and financial systems. Always provide the specific number requested.
What if my license number has letters in it?
Some states include letters in their driver's license numbers — this is normal and varies by state. When entering your license number into a form, include both the letters and numbers exactly as they appear on your license. Don't try to convert letters to numbers or skip them.
Do I need to memorize my license number?
You don't need to memorize it, but it's helpful to know where to find it quickly. Keep a photo of your license in a safe place, or write the number down separately if you use it frequently. Never share photos of your license online or with people you don't trust, especially if your Social Security number is visible.
