Your credential number is a unique identifier printed on your driver's license or state ID that helps government agencies and businesses verify who you are

The credential number is a separate code from your driver's license number. It appears on your physical license card and serves as proof that your license was issued by your state's Department of Motor Vehicles (or equivalent agency). When you renew your license or get a replacement card, you receive a new credential number — it changes each time you get a new physical card, even if your license number stays the same.

This number matters because it's what systems check to confirm your license is current and legitimate. Banks, employers, and government offices sometimes ask for it during verification processes. Understanding what it is and where to find it prevents confusion when you're filling out forms or talking to someone who needs to verify your identity.

Key Takeaways

  • Your credential number is printed on your physical driver's license or state ID card and changes each time you renew or replace the card.
  • It is different from your driver's license number and serves as proof your license was officially issued by your state's motor vehicle agency.
  • You'll find the credential number in a specific location on your card — usually near the bottom or on the back, depending on your state's format.
  • Businesses and government offices may ask for this number when they need to verify that your license is valid and current.

Where the credential number appears on your card

The location varies by state, but most place it on the front of the card near the bottom, sometimes labeled as "Credential Number," "Document Number," or "ID Number." A few states print it on the back. The number is typically 8 to 12 characters long and may include both letters and numbers.

If you're unsure where yours is located, check your state's Department of Motor Vehicles website — most have a diagram showing exactly where each piece of information sits on the card. You can also call your local DMV office and ask; they can tell you in seconds.

How it differs from your driver's license number

Your driver's license number is a permanent identifier assigned to you by your state and stays the same throughout your life (unless you move to a different state). Your credential number, by contrast, is tied to the physical card itself. When you renew your license every few years, you get a new credential number printed on your new card.

Think of it this way: your driver's license number is like your Social Security number — it identifies you personally. Your credential number is like a serial number on a passport — it identifies that specific document. This distinction matters because some forms ask for one and some ask for the other.

Why credential numbers matter for verification

When a business or government office verifies your identity, they often run your information through a system that checks whether your license is valid, not suspended, and not expired. The credential number helps them pull up the exact record of your current card. Without it, they might have outdated information from a previous license.

Banks sometimes ask for it when you open an account. Employers may request it during a background check. Government agencies use it to confirm you are who you say you are. In each case, the credential number lets them verify that your license is legitimate and current.

What to do if you can't find your credential number

If your card is damaged or the number is hard to read, you can contact your state's Department of Motor Vehicles directly. You'll need to provide your name, date of birth, and driver's license number. They can tell you your credential number over the phone or by mail.

If you've lost your license entirely, you'll need to explore for a replacement card. The DMV will issue you a new credential number on the replacement. Most states allow you to request a replacement online, by mail, or in person at a local office.

Credential numbers and online identity verification

Some online services ask for your credential number as part of their identity verification process. This is common when you're setting up accounts with government agencies, financial institutions, or services that need to confirm you are who you claim to be. Always verify you're on a legitimate website before entering this information.

If a website or caller asks for your credential number and you're unsure whether they're legitimate, hang up or close the browser and contact the organization directly using a phone number or website you know is real. Scammers sometimes pose as government agencies or banks to collect personal information.

Frequently Asked Questions

Does my credential number change if I renew my license?

Yes. Each time you renew your license or get a replacement card, you receive a new credential number. Your driver's license number stays the same, but the credential number on the physical card changes because you have a new physical card.

What if I moved to a different state — do I keep the same credential number?

No. When you get a new license in a different state, you receive a new credential number issued by that state's motor vehicle agency. Your old credential number is no longer in use.

Can someone use my credential number to commit fraud?

A credential number alone is not enough to commit fraud, but combined with other personal information it could be misused. Treat it like you would your driver's license number — don't share it with people or websites you don't trust. If you believe your information has been compromised, contact your state's DMV.

Is the credential number the same as the barcode on my license?

No. The barcode on your license encodes multiple pieces of information from your card. The credential number is a separate, human-readable code printed elsewhere on the card. Some systems scan the barcode; others ask you to provide the credential number directly.
