Your Idaho driver's license number appears in four places on the physical card

Your Idaho driver's license number is printed in the upper right corner of the front of your card, below your photograph. It is also printed on the back of the card in the lower left section. The number is 8 digits long and unique to you — it stays the same for the life of your license unless you request a replacement card.

If you have lost your physical card or cannot read the number clearly, you can find it through your Idaho Transportation Department (ITD) online account, by phone, or by visiting an ITD office in person. Each method takes a different amount of time and requires different information from you.

Key Takeaways

  • Your Idaho driver's license number is printed in the upper right of the front of your card and again on the back in the lower left.
  • You can retrieve your number online through your ITD account without visiting an office or calling.
  • If you do not have an online account, you can call ITD's customer service line with your name, date of birth, and Social Security number.
  • An in-person visit to any ITD office will give you your number when ready, but requires a trip during business hours.
  • Your license number does not change when you renew your license, so an old card or document will show the same number.

Check your ITD online account

The fastest way to find your number without leaving home is through the ITD website. Go to itd.idaho.gov and select "Online Services" or "My Account." You will need to create an account if you do not already have one, which requires your driver's license number, date of birth, and the last four digits of your Social Security number.

If you cannot remember your number to set up the account, this method will not work for you — you will need to use the phone or in-person option instead. Once your account is active, you can log in at any time to view your license information, including your full 8-digit number.

Call ITD customer service

You can reach ITD by phone at 208-321-8000 during business hours, Monday through Friday, 8 a.m. to 5 p.m. Mountain Time. Have your full legal name, date of birth, and Social Security number ready when you call. The representative will verify your identity using this information and then read your license number to you over the phone.

Wait times vary depending on the time of day and day of the week. Early morning calls (8 a.m. to 10 a.m.) typically have shorter waits than mid-day or late afternoon calls. You do not need to schedule an appointment — this is a walk-up phone line.

Visit an ITD office in person

Every ITD office can look up your license number while you wait. Bring a form of identification — a passport, state ID, or other government-issued ID works — and your Social Security number. You do not need an appointment. Office hours are Monday through Friday, 8 a.m. to 5 p.m., though some offices may have different hours, so check the ITD website for the location nearest you.

The main ITD office is located at 3311 W. State Street in Boise. Regional offices are in Coeur d'Alene, Lewiston, Pocatello, and Twin Falls. An in-person visit usually takes 15 to 30 minutes depending on how busy the office is that day.

What to do if your card is damaged or unreadable

If your license number is printed on your card but you cannot read it clearly due to wear, fading, or damage, you can request a replacement card from ITD. A replacement card costs $20 and takes about two weeks to arrive by mail. You can order a replacement through your online account, by phone, or in person at any ITD office.

You do not need a new license number — the replacement card will have the same 8-digit number printed on it. The only time your number changes is if you request a new license number specifically, which is rare and usually only happens if you believe your number has been compromised or used fraudulently.

Your license number versus your driver's license card number

Idaho uses two different numbers on your license, and it is important not to confuse them. Your driver's license number is the 8-digit number in the upper right of the front and lower left of the back — this is what you use to identify yourself. Your card number is a separate identifier printed elsewhere on the card that tracks the physical card itself, not you as a driver.

When you renew your license or request a replacement card, your driver's license number stays the same, but your card number changes because you have a new physical card. If someone asks for your "license number," they want the 8-digit driver's license number, not the card number.

Frequently Asked Questions

Does my Idaho driver's license number change when I renew?

No. Your 8-digit driver's license number stays the same for the entire time you hold an Idaho license. It does not change when you renew, get a replacement card, or update your address. The only thing that changes is the card itself and its expiration date.

What if I moved out of Idaho but still have my old license?

You can still find your number on the card itself — it is printed in the upper right of the front and lower left of the back. If you need to verify it or have questions about your old Idaho license, you can call ITD at 208-321-8000, though they may direct you to your new state's DMV if you now hold a license elsewhere.

Can I look up someone else's driver's license number?

No. ITD will only release a driver's license number to the person who holds the license. You cannot retrieve another person's number by phone or online, even if you have their name and date of birth. This is a privacy protection.

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

If you have an Idaho driver's license, your driver's license number is your ID number. They are the same 8-digit number. Idaho does not issue separate ID cards with different numbers — your license number is your identifier in the state system.
