To make online changes with the FMCSA, you'll need an FMCSA Portal account. This account is now linked to a Login.gov account, which serves as the single sign-on service for many US Government online services. If you don't have a Login.gov account, you'll need to create one first. Once you have a Login.gov account, you can then create your FMCSA Portal account and make online changes. 

Company Officials and Associates of a Company (which includes employees and third-party service providers) can access the Registrations Options functionality via their FMCSA Portal account to complete the following updates online: 

• Applying for additional operating authority 
• File a biennial update (MCS-150) 
• Change of address 
• Reinstate Operating Authority 
• Reapplication for USDOT Number after revocation 
• Update cargo tank 
• Update HM Safety Permit (MCS-150B) 

Here's a step-by-step guide to create your FMCSA Portal account:

Step 1 -- Obtain Your USDOT PIN: Make sure you have your company info handy (i.e., EIN, USDOT) and go to https://safer.fmcsa.dot.gov/. Select the option to request a PIN and follow the prompts. The PIN will be sent to the e-mail or cell phone currently on file. 

Step 2 -- Obtain Your Login.gov E-mail: Login.gov is the official, single sign-on service for US Government services online. If you don't already have a Login.gov e-mail, sign-up for free at https://login.gov/create-an-account/

Step 3 -- Create the FMCSA Portal Account: Visit the FMCSA Portal website at https://portal.fmcsa.dot.gov/login and walkthrough the account instructions. You'll only need to go through the steps and use your FMCSA PIN once during account set-up; after that, the Login.gov e-mail address is all you'll need to access your company record.

The FMCSA Portal provides single sign-on access to FMCSA systems via a single password and user ID, which must be set up via Login.gov. The FMCSA Portal enables Federal, State, and industry users to access the Agency's existing information systems with a single set of credentials and have easy access to safety data about the companies regulated by the FMCSA. Motor carriers, brokers, freight forwarders, intermodal equipment providers, and cargo tank facilities will have secure access to their company information on file with the FMCSA.
