1 min. readlast update: 03.29.2024

You need a USDOT PIN so that you can access the DOT’s system and make changes to your USDOT number. This can include filing MCS-150 / Biennial Updates, Voluntarily Dissolving your USDOT, requesting an Authority Rating Letter or Operating Letter, as well as disputing any negative ratings such as crashes, inspections or insurance lapsing. 

The USDOT PIN replaces the MC and MX PINs and is provided when you register for a USDOT Number. However, you can request a PIN online by clicking here. PIN numbers can only be received by mail. When requesting the PIN, it will be mailed to current mailing address on file for your DOT Number.

Please note, if your DOT Number is inactive, you will not be able to request a new PIN until the DOT has been reactivated.
