FMCSA no longer uses a USDOT PIN. Since FMCSA's Motus registration system (motus.dot.gov) opened on May 19, 2026 (legacy systems were retired May 14), you sign in with Login.gov and link your USDOT number to your account. If you were searching for a PIN so you could file your MCS-150 before your biennial deadline, you do not need one — here is how sign-in works now.
Why You No Longer Need a USDOT PIN
Motus replaced FMCSA's older registration systems, and sign-in now runs through Login.gov, the federal sign-in service. Instead of typing a PIN, you sign in with your Login.gov account and link your USDOT number to it. Once the link is in place, you use the same Login.gov sign-in for your MCS-150 and other registration updates.
How to Sign In and Link Your USDOT Number
- Create or sign in to your Login.gov account. Go to login.gov and create a free account if you do not have one. If you used the old FMCSA Portal, use the same email address the company official had on file there.
- Complete identity verification when Login.gov asks for it. Follow Login.gov's on-screen instructions, and make sure the details you enter match your identity documents.
- Sign in at motus.dot.gov and link your USDOT number. Choose the option to claim your existing USDOT number and connect it to your account. FMCSA says to use the same Login.gov email that was on file for the company official in the old FMCSA Portal; the claim imports your existing data so you review it rather than retype it.
- Review your record and file your update. Once your USDOT number is linked, open your registration and file the MCS-150. Our step-by-step filing guide walks through the form fields.
What to Do If Identity Verification Fails
Two different systems are involved, so start by working out which step is failing:
- Login.gov identity verification fails. That step belongs to Login.gov, not FMCSA. Use the Login.gov help center for verification problems.
- Your USDOT number will not link or the claim does not match. Use FMCSA's Motus help resources, or contact FMCSA through the contact options on fmcsa.dot.gov. Have your USDOT number and legal business name ready.
- Do not apply for a new USDOT number to get around a sign-in problem. Your existing number carries your biennial schedule and history.
FMCSA does not publish a turnaround time for resolving sign-in issues, so start well before the last day of your due month.

With a filing service, the MCS-150 is prepared and submitted for you. FastMCS150 charges $175 standard, plus $25 only if you need Login.gov setup help, since the identity-verification step cannot be fully automated. The $400 option covers lifetime updates.
Avoiding Sign-In Problems Next Cycle
- Set up Login.gov and link your USDOT number now, before your next biennial deadline, rather than on deadline week.
- Keep the account's email and phone current. If the person who holds the Login.gov account leaves the company, use FMCSA's help resources to sort out access before the next filing is due.
- Keep your USDOT number, legal name, and principal address in your compliance file so you can answer verification questions quickly.
Bottom line: There is no USDOT PIN to find anymore. Sign in to Motus with Login.gov, link your USDOT number to your account, and file. If identity verification fails, use Login.gov's help center for the Login.gov step and FMCSA's help resources for linking your USDOT number.
