When FMCSA authority goes to NOT AUTHORIZED, carriers have two paths: reinstate the existing MC number, or apply for a brand-new authority with a new MC. The decision depends on four things: the entity, the history, the brand, and the speed requirement. Most of the time reinstatement wins; the exceptions are worth understanding.
When to Reinstate (Usually)
Reinstatement is almost always the right call when all of the following are true:
- Same business entity. No change in EIN, ownership, or legal structure. The underlying company continues as before.
- Curable causes. The revocation was triggered by insurance, BOC-3, MCS-150, or a payable civil penalty — not by a serious safety rating or unsafe-carrier order.
- Brand value in the MC number. Existing broker approvals, shipper relationships, and load-board reputation are tied to the carrier identity. Starting over loses that continuity.
- Speed matters. Reinstatement typically clears within 48 hours. A new OP-1 application runs 4 to 6 weeks. For most carriers, the 4 to 6 weeks without authority is the more expensive outcome.
When New Authority Is the Better Path
New authority makes sense in a narrower set of cases:
- The entity is genuinely changing. A new EIN, a new LLC, a different ownership structure, or a sale to new principals is a legitimate reason to start fresh. Reinstating under an entity that no longer exists is not an option.
- A serious safety-rating flag follows the record. A Conditional or Unsatisfactory safety rating, or an unsafe-carrier out-of-service order, stays on the carrier's record through reinstatement. For carriers with that history, a new authority may be the only way to rebuild.
- Repeated revocations. FMCSA scrutiny tends to tighten on carriers with multiple revocation cycles. A legitimate entity change paired with new authority sometimes makes more sense than repeatedly reinstating.
The honest caveat: FMCSA specifically watches for “chameleon carriers” — carriers that try to shed a bad safety record by restarting under a new MC while operating the same equipment and same drivers. That practice is treated as fraud and can result in denial of the new authority plus enforcement against the principals. Entity change must be substantive, not cosmetic.
Cost and Timeline Comparison
| Factor | Reinstatement | New Authority |
|---|---|---|
| Typical timeline | 48 hours to 5 business days | 4 to 6 weeks |
| FMCSA fees | $80 reinstatement fee | $300 OP-1 per authority type |
| Operating history | Preserved (MC, USDOT, CSA) | Reset to zero |
| New entrant audit | Not required (already past) | Required within 18 months |
| Broker re-approval | Not required | Required with new MC |
The Short Answer
Reinstate unless something about the entity or the history makes reinstatement impossible or counterproductive. Speed, cost, and preserved history make reinstatement the default for carriers whose business continues unchanged.
