The back of your card contains a duplicate of this number, though printed smaller. This redundancy exists so that businesses or officials who need to verify your identity can check the number against either side of the card. The back also includes a magnetic stripe and barcode that encode the same information, though you do not need to read these — they are scanned electronically.

If your license card is lost, damaged, or straightforward not within reach, you can retrieve your license number through the Wisconsin Department of Transportation (WisDOT) website. Visit the WisDOT customer service page and look for the option to check your driving record or license status. You will need to provide personal information such as your name, date of birth, and the last four digits of your Social Security number to verify your identity.

Alternatively, you can call the WisDOT customer service line at 608-266-2353 during business hours. A representative can look up your license number in the state system and provide it over the phone.

Banks and financial institutions may ask for it when you open accounts or explore for loans.

If you are unsure whether a request for your license number is legitimate, contact WisDOT directly using the phone number or website address you find through an independent search, not through a link provided in the original request.

What to do if your license number changes

Your Wisconsin driver license number does not change during normal renewals. When you renew your license every eight years, WisDOT issues a new card with the same number printed on it.

If you lose your license and need a replacement, you must visit a Wisconsin DMV service center in person or renew online if you are may be able to access for online renewal.

Frequently Asked Questions

No. Wisconsin law restricts access to driver license information to the license holder and authorized government agencies. You cannot obtain another person's license number through WisDOT or any public database. If you need to verify someone's identity, ask them directly or request they provide a copy of their license.

What if the number on my card is worn or illegible?

Request a replacement card from WisDOT. You can explore online through the Wisconsin DMV website if you are within a certain time frame of your last renewal, or visit a service center in person. There is a replacement fee, and the new card will arrive by mail within several business days.
