> FMCSA rejects OP-1 applications for predictable reasons: name mismatches, missing BOC-3, late insurance, P.O. box addresses, and EIN errors. Each is fixable and avoidable.

## TL;DR

> FMCSA rarely "rejects" an OP-1 outright — it issues a deficiency letter and holds the application in PENDING. The most common deficiencies are name mismatches with the state LLC, missing BOC-3, late BMC-91 insurance, P.O. box addresses, EIN errors, and the wrong authority type selected. Each is fixable.

## Key takeaways

- FMCSA holds OP-1 applications in PENDING with a deficiency letter; an outright denial is rare.
- Top deficiencies: legal-name mismatch with the state LLC record, EIN mismatch, P.O. box addresses, wrong authority type, missing BOC-3, late BMC-91, and missing broker bond.
- The $300 government filing fee is non-refundable regardless of outcome; the application stays open until the deficiency is cured.
- Under 49 CFR §365.115, a denied applicant has 20 days to petition for reconsideration — but most cases never reach formal denial.
- Most deficiencies clear within 1–2 weeks once the corrected filing reaches FMCSA via li-public.fmcsa.dot.gov.

## FAQ

### Why did FMCSA reject my MC application?

FMCSA does not technically "reject" a properly submitted OP-1 — it issues a deficiency letter or holds the application in PENDING status until the issue is resolved. The most common deficiencies are: legal-name mismatch with the state LLC record, missing BOC-3, BMC-91 insurance filing not received, P.O. box used instead of a physical address, EIN that does not match the legal entity, and selecting the wrong authority type. Each is fixable and the $300 fee carries forward.

### Will I get my $300 FMCSA fee back if my application is rejected?

No. The $300 government filing fee is non-refundable once the OP-1 is submitted, regardless of outcome. The fee covers FMCSA processing time, not the issuance of the authority. If your application is denied or you withdraw it, the $300 stays with the FMCSA. Professional filing services like FastAuthority refund their separate service fee under acceptance-guarantee terms — but the $300 government fee is gone either way.

### How do I respond to an FMCSA deficiency letter?

The deficiency letter cites the specific issue — name mismatch, missing filing, insurance gap, etc. Pull the source document the FMCSA is comparing against (state secretary of state record, IRS EIN letter, insurer BMC-91 confirmation), correct the OP-1 or supplemental filing, and respond through the FMCSA Licensing & Insurance system at li-public.fmcsa.dot.gov. Most deficiencies clear within 1-2 weeks once the corrected filing is on record.

### Can I appeal a rejected operating authority application?

Yes. Under 49 CFR §365.115, an applicant whose application is denied can file a petition for reconsideration with FMCSA within 20 days of the denial decision. The petition must specify factual or legal errors in the original decision. In practice, most "rejections" are deficiency holds rather than denials — fixing the cited issue is faster than appealing, and the underlying application stays on the docket.

### How long does FMCSA give me to fix a deficiency?

There is no hard FMCSA deadline — the application stays in PENDING status indefinitely until the deficiency is cured. Practically, applicants who do not respond within 60-90 days can have their application administratively closed, requiring a fresh OP-1 and a new $300 fee. The right move is to respond to deficiency letters within 14 days so the authority can activate the moment vetting closes.
