USDOT Login and Portal Access Help

To complete a USDOT login, open the official FMCSA page through {site}, choose the portal that matches your task, and use the sign-in option shown there. Most company users signing in to the FMCSA Portal use their Login.gov email address, password, and configured authentication method.

A USDOT Number is a company identifier, not a username. Do not enter a USDOT Number in a username field unless the official service specifically requests it.

Where is the official USDOT login page?

Start at {site} and look for Portal Login, FMCSA Portal, or the name of the USDOT service you need. An official page should be on a government domain and identify the U.S. Department of Transportation or the Federal Motor Carrier Safety Administration.

Search results may show private filing services alongside government pages. A private page that requests company information is not automatically the official USDOT portal. Avoid entering credentials after opening a link from an unexpected message, advertisement, or third-party directory.

Before signing in, check that the page:

• Uses a government domain ending in .gov.
• Names the relevant DOT agency or system.
• Offers the expected government sign-in service, such as Login.gov.
• Does not ask for credentials before you reach the secure sign-in screen.

How do I log in to the USDOT portal?

The FMCSA Portal uses Login.gov for most motor carrier and company users. Login.gov is the federal sign-in service that supplies the email, password, and two-factor authentication used to confirm the user’s identity.

1. Open the official FMCSA Portal entry point.
2. Select Sign in with Login.gov when that option is displayed.
3. Enter the email address connected to both Login.gov and the FMCSA Portal profile.
4. Enter the Login.gov password.
5. Complete authentication with a method already configured on the Login.gov account.
6. After returning to the portal, confirm that the correct company roles and USDOT Number are displayed.

DOT employees or contractors with an eligible government credential may see MyAccess instead. They should follow their agency’s instructions rather than use the company-user option.

What if I forgot my USDOT username or password?

For an FMCSA Portal account linked to Login.gov, the username is normally the email address used with Login.gov. Password recovery begins on the Login.gov sign-in screen by selecting Forgot your password?. The FMCSA Portal itself does not reset a Login.gov password.

If the forgotten item is the email address, check saved account records and official messages from Login.gov or FMCSA. Do not create a second Login.gov account merely because the original email is uncertain; a new account may not be connected to the existing portal roles.

A USDOT PIN is separate from a Login.gov password. The PIN may be required when establishing or claiming certain company access, but it is not the routine password for a USDOT log in. PIN assistance begins in the official USDOT PIN area on the FMCSA site.

Why is my USDOT login not working?

If a USDOT login fails, first identify whether the error appears on Login.gov or after the user returns to the FMCSA Portal. That distinction determines which support team and account record need attention.

• Credentials rejected: Confirm the email address, remove accidental spaces, check keyboard settings, and use Login.gov password assistance if needed.
• Page does not load: Reopen the portal from the official FMCSA site, try a private browser window, and disable a browser extension only if it may be blocking redirects or cookies.
• Account locked: Stop repeated attempts and follow the notice displayed by the sign-in service. Do not guess at credentials continuously.
• Authentication fails: Use another authentication method already registered on the Login.gov account. If no configured method remains available, use Login.gov’s official account-help process.
• Sign-in succeeds but company access is missing: Confirm that the Login.gov email matches the FMCSA Portal email and ask the company’s Portal Company Official to review the user’s role.

If the browser repeatedly returns to the login screen, allow required cookies and redirects, then start a fresh session from the official portal entry point.

Which USDOT portal or account do I need?

“US DOT login” can refer to several systems. USDOT agencies operate different services, and not every USDOT service uses the same account or authentication process.

• FMCSA Portal: Used by registered companies and authorized associates to reach assigned FMCSA systems and company information.
• Company Official account: Used by the person responsible for managing portal access associated with a USDOT Number.
• Associate of a Company account: Used by an employee or authorized service provider whose access is approved through the company.
• Motus: The USDOT registration system for registration-related company activity; users should choose it only when their task or official FMCSA guidance directs them there.
• Login.gov: Supplies sign-in credentials and authentication, but does not by itself grant an FMCSA company role.
• MyAccess: Intended for eligible DOT personnel using agency credentials, not ordinary company users.

If the USDOT portal accepts the login but does not show the expected record, the problem may be a missing portal role rather than an incorrect password.

How do I contact USDOT support about portal access?

For an unresolved FMCSA company-account or portal-role problem, use the official Ask FMCSA support option available from the FMCSA registration area. Choose the category for portal, registration, or account access and describe where the failure occurs.

Include the USDOT Number, the portal or system name, the exact error message, and whether Login.gov authentication succeeded. Do not send a password, authentication code, backup code, or full sensitive identity document.

If the problem occurs entirely on the Login.gov screen, use the Login.gov Help Center. If sign-in succeeds but an FMCSA role or company record is unavailable, contact FMCSA support or the organization’s Portal Company Official. Users of another DOT agency system should use that system’s official help channel because FMCSA support may not control the account.
