If you have your driver’s license handy, or an expired license, you can find your driver’s license number front and center. 

However, if you’ve lost your license, you may actually still need your license number to order a replacement. 

Here are some other places where you may find your driver’s license number:

  • On an old or expired license
  • On your vehicle registration. 
  • On renewal notices you’ve received from the DMV. 
  • On car lease or car loan agreements. 
  • In your car insurance policy. 
  • On your driving record

If those options fail, you may need to visit your local DMV office and present proof of your identity in order to get a replacement.
