The credential number is a unique identifier printed on your state ID or driver's license that the issuing agency uses to track your record

Every state ID and driver's license has a credential number — sometimes called a document number or license number — printed somewhere on the front or back. This is not the same as your driver's license number. The credential number identifies the specific physical card you hold, while your license number identifies you as a person licensed to drive or hold an ID.

The credential number matters when you need to report a lost or stolen ID, when you're renewing, or when a government agency needs to verify which version of your ID they're looking at. It's a tracking tool for the state, not for you to memorize or use in daily life.

Key Takeaways

  • The credential number is printed on your ID card itself and identifies that specific physical card, separate from your driver's license number.
  • Location varies by state — check the front or back of your card, often near the issue or expiration date.
  • You'll need this number if you report your ID lost or stolen, or if a state agency asks you to reference a specific card.
  • This number changes each time you renew your ID, because you receive a new physical card with a new credential number.

Where to find your credential number on your ID

The location depends on your state, but it's always printed directly on the card itself. Most states place it on the front near the bottom, sometimes below your photo or next to your signature line. Others print it on the back. Look for a label that says "Document Number," "Credential Number," "ID Number," or sometimes just a number without a label.

If you can't find it, check your state's DMV website — they usually show a sample ID with all fields labeled. You can also call your local DMV and describe where you're looking; they can tell you exactly what to look for on your state's version.

How credential number differs from your driver's license number

Your driver's license number is your permanent identifier as a licensed driver in that state. It stays the same for years, even across multiple renewals. The credential number, by contrast, is tied to the physical card you're holding right now. When you renew your license, you get a new card with a new credential number, but your driver's license number usually stays the same.

Think of it this way: your driver's license number is like your Social Security number (it identifies you), while your credential number is like a serial number on a passport (it identifies the document itself). If you lose your card and get a replacement before your renewal date, you'll have a new credential number but the same driver's license number.

When you'll actually need to reference your credential number

Most people never need to use this number. But you'll want to have it handy if you report your ID lost or stolen — the DMV will ask for it to cancel that specific card and prevent someone else from using it. You may also need it if you're replacing a damaged card before your renewal date.

Some government agencies or financial institutions may ask for it when verifying your identity, though this is less common. If an agency asks you to reference your ID, they may want the credential number to pull up the exact record of that card rather than just your general license record.

What happens to your credential number when you renew

Every time you renew your ID or driver's license, you receive a new physical card. That new card has a new credential number printed on it. Your old credential number becomes inactive — it's no longer tied to a valid card. Your driver's license number, however, typically remains the same unless your state has a specific reason to change it (like a name change or correction to your record).

This is why credential numbers are useful for the DMV's internal tracking. They can see which version of your ID is current and which ones have expired or been replaced. If you ever need to reference your ID in an official context, using the credential number ensures there's no confusion about which card you're talking about.

How to read your credential number correctly

The credential number is usually a string of numbers and sometimes letters. The exact format varies by state — some use 8 digits, others use 10 or 12. Don't try to interpret what the numbers mean; they're just a unique code assigned by your state's DMV system. Write it down exactly as it appears on your card, including any letters.

If you need to provide it over the phone or in writing, read it slowly and spell out any letters. If you're typing it into an online form, make sure you're entering it in the field labeled "Credential Number" or "Document Number," not in a field asking for your driver's license number.

Frequently Asked Questions

Is my credential number the same as my driver's license number?

No. Your driver's license number identifies you as a licensed driver and usually stays the same for years. Your credential number identifies the specific physical card you're holding and changes each time you renew or get a replacement card.

What do I do if I can't find the credential number on my ID?

Check both the front and back of your card carefully — it's printed somewhere on the physical card itself. If you still can't locate it, visit your state's DMV website for a labeled sample ID, or call your local DMV office and describe your card. They can tell you exactly where to look.

Do I need to memorize my credential number?

No. You only need it in specific situations, like reporting a lost or stolen card. Keep a photo of your ID or write the number down somewhere safe if you think you might need it, but there's no reason to memorize it for everyday use.

Does my credential number change if I move to a different state?

Yes. When you get a new ID or driver's license in a different state, you'll receive a new credential number assigned by that state's system. Your old credential number from your previous state is no longer active.

Can someone use my credential number to impersonate me?

The credential number alone is not enough to impersonate you — it's just a tracking number for a specific card. However, if someone has your physical ID card, they could use it fraudulently. If your card is lost or stolen, report it to your DMV right away so they can deactivate that credential number.
