Request a PIN Number


As of June 30, 2023, the online PIN request system is temporarily unavailable. However, you may still request a PIN to be sent by mail to the mailing address on file, just as indicated below. We apologize for any inconvenience caused and appreciate your patience

A PIN can be requested online and delivered in one of two ways:

Please Note: Brokers may only request their PIN by mail through the US Post Office. FMCSA will continue to work on allowing Brokers to request their USDOT PIN information via email in the near future. 

You can also request a PIN by going to and then clicking on the “Click here to request a USDOT Number PIN be emailed” prompt or "Click here to request a USDOT Number PIN be mailed to the address on file."

How Long Will It Take by Mail?

Please allow 7-10 business days to receive your PIN by mail. It will be mailed to the mailing address on file with the FMCSA.

What is the format of the USDOT Number PIN?
