What do I do next?
 
If you arrived at this page from a link in your FMCSA Portal account, simply go back to your Portal account and look for the "Registration" option in the top menu.  

 
If you do not see the "Registration" option, you can use the "Account Management" > "My Profile" > "Portal Roles" tab to add (if you are a Company Official) or request (if you are an Associate of a Company) the necessary roles for making online updates. The “Modify Company Information” and “View Sensitive Company Information” roles allow access to make changes to FMCSA Registration.
