Your license control number is a unique identifier printed on your driver's license that the DMV uses to track your record

A license control number (sometimes called a control number or LCN) is a code specific to your driver's license. It appears on the physical card itself, usually near your license number, and the DMV uses it to organize and retrieve your driving record in their system. When you renew your license, get a replacement card, or the DMV needs to look up your information, this number helps them find the right file among millions of others.

The number is not the same as your driver's license number. Your license number identifies you as a driver; your control number identifies that specific card and the record attached to it. If you lose your license and get a replacement, you may receive a new control number, depending on your state's system.

You will need this number when you renew your license by mail, when you request a copy of your driving record, or when you contact the DMV about your account. Having it on hand saves time because the DMV staff can pull up your file when ready instead of searching by name and date of birth alone.

Key Takeaways

  • Your license control number is printed on your driver's license and helps the DMV locate your specific record in their system.
  • It is different from your driver's license number and may change if you receive a replacement card.
  • You will need this number when renewing by mail, requesting your driving record, or contacting the DMV about your account.
  • The exact location of the control number on your card varies by state, so check your license or your state's DMV website to find it.

Where to find your license control number on your card

The location of your control number depends on which state issued your license. On most modern licenses, it appears in small print somewhere on the front of the card—often near the bottom, in a corner, or along the edge. Some states print it on the back. Your state's DMV website usually shows a sample license with the control number highlighted so you know exactly where to look.

If you cannot locate it on your physical card, you can find it on your renewal notice or any official DMV document related to your license. You can also call your state's DMV directly and provide your name and date of birth; they will give you the number over the phone. Many states also let you look it up online through their DMV portal if you log in with your license number and other identifying information.

When you will need to provide your license control number

The most common reason to use your control number is when you renew your license by mail. The renewal form will have a space for it, and including it speeds up processing because the DMV can match your paperwork to your existing record without manual searching.

You may also need it if you request an official copy of your driving record—for insurance purposes, a court case, or a job background check. When you order online or by phone, providing the control number ensures you receive the correct record. Some states require it; others accept it as optional but recommended.

If you contact the DMV about a problem with your account—a missing payment, a suspended license, or an error in your record—having your control number ready will help the staff locate your file faster and resolve the issue more quickly.

What happens if you do not have your control number

Not having your control number is not a barrier. The DMV can still find your record using your name, date of birth, and address. However, the search takes longer, especially if your name is common or if you have moved recently. If the DMV cannot when ready locate your file, they may ask for additional information like your Social Security number or the number of your old license.

If you are renewing by mail and do not include your control number, your process may be delayed while staff manually match your paperwork to your record. Including it when you have it is straightforward a way to make the process faster and smoother.

License control numbers and privacy

Your control number is not sensitive information in the way your Social Security number or date of birth is. It is printed on your license for a reason—it is meant to be shared with the DMV and other official bodies. You do not need to guard it like a password.

That said, there is no reason to volunteer it to private companies or individuals who do not need it. If a business or organization asks for your control number and you are unsure why they need it, you can ask them to explain. Legitimate requests usually come from the DMV itself, insurance companies verifying your driving record, or courts and employers conducting background checks.

Frequently Asked Questions

Does my control number change when I renew my license?

It depends on your state's system. Some states keep the same control number throughout your driving life; others issue a new one with each renewal or replacement card. Check your renewal notice or contact your state DMV to find out how your state handles this.

What if I lost my license and got a replacement—do I get a new control number?

You may or may not, depending on your state. Some states reuse the same control number for replacement cards; others assign a new one. Your replacement card will show which number applies to you. If you are unsure, the DMV can tell you over the phone.

Can I renew my license online without my control number?

Most states allow online renewal without your control number, though having it makes the process faster. If your state's website asks for it and you do not have it, you can usually proceed by entering your license number and other personal details instead.

Is my control number the same as my license number?

No. Your license number is your main identifier as a driver; your control number is a separate code the DMV uses to organize records. Both appear on your card, but they serve different purposes.
