Can I update my MCS-150 online?
Yes. FMCSA accepts MCS-150 filings online through its Motus registration system at motus.dot.gov, by paper mail, or through a third-party filing service. Online filing is the fastest - same-business-day SAFER reflection in most cases. Paper mail takes 4-6 weeks for FMCSA to enter the data and reflect it in SAFER.
Motus (motus.dot.gov) is the official FMCSA online filing channel for MCS-150 as of May 2026, replacing the legacy URS portal. Carriers sign in with a Login.gov account connected to their USDOT record. Once signed in, the carrier can view current registration, update the MCS-150 fields, submit electronically, and download a confirmation receipt.
Paper filing is still permitted but is the slowest option. The carrier prints Form MCS-150 from the FMCSA website, fills it out, and mails it to FMCSA at the address printed on the form. The IRS-style processing timeline is 4-6 weeks before the SAFER record reflects the update.
Third-party filing services (Fast MCS-150 Filing, others) submit electronically through the same FMCSA system that direct-online filers use. The substantive filing is identical; the service adds preparation, monitoring, and confirmation. The trade-off for the $110 service fee is convenience - the online filing is straightforward but does require setup time on the first use.
Gather your data (vehicle counts, mileage, contact info, classifications) before signing in so you do not lose work mid-form on a long submission.
