> Changed your legal entity, DBA, or business name? Here is the FMCSA process for re-filing MCS-150 so your USDOT record matches your new paperwork.

## TL;DR

> Under 49 CFR §390.19, any change to legal name, DBA, or operation type triggers an out-of-cycle MCS-150 within 30 days. Same-entity renames keep your USDOT; new legal entities require a fresh USDOT application.

## Key takeaways

- Same legal entity (same EIN, renamed LLC or new DBA) keeps the USDOT and updates via §390.19 MCS-150.
- New legal entity (dissolved old LLC, sold company) cannot inherit the prior USDOT — apply for a new one.
- Finish the secretary-of-state rename before opening URS so the FMCSA pulls clean authoritative data.
- For-hire carriers must update operating authority records (OP-1 / MCSA-5889) and BOC-3 in parallel with MCS-150.
- Filing the §390.19 update does not reset the regular biennial schedule.

## FAQ

### Do I need to file a new MCS-150 after changing my business name?

Yes — under 49 CFR §390.19, any change to legal name, DBA, address, or operation type triggers an out-of-cycle MCS-150 within 30 days. The biennial schedule still applies, but the name change requires its own filing on top of the regular 24-month update.

### Is a name change the same as transferring my USDOT?

No. A name change keeps the same USDOT number under the same legal entity (you renamed the LLC, swapped a DBA, etc.). A transfer to a new legal entity is a different filing — the new entity must apply for its own USDOT and operating authority. If you dissolved one LLC and formed another, you cannot keep the old USDOT.

### What documents does the FMCSA need for a name change?

For a same-entity name change, the FMCSA accepts the MCS-150 update plus state-level evidence of the renaming (amended articles, DBA filing, or secretary-of-state certificate). MC operating authority holders may also need to update Form OP-1 / MCSA-5889 to keep the authority record consistent.

### How long does an FMCSA name change take?

The MCS-150 portion processes in 1-2 business days once submitted. Authority record updates (if required) take longer — typically 2-4 weeks. Do not stop running while the update processes; the existing authority remains valid throughout.
