Before you tender a load, the single field that decides whether the carrier is legally allowed to haul is their MC number's authority status. Not the certificate, not the insurance cert, not the carrier packet — the federal authority status field. This guide walks the lookup step by step, decodes every status value the registry returns, and explains the patterns that make 'active' less reassuring than it looks.
To verify an MC number is active, look up the carrier in the federal registry and confirm three fields: authority status reads ACTIVE, out-of-service date is blank, and the legal name on file matches the carrier you are talking to. Anything else — PENDING, REVOKED, RESCINDED, or a populated OOS date — means the carrier is not currently allowed to operate. Confirm same-day; status can change between onboarding and tender.
An MC number is an operating-authority identifier the federal regulator assigns to for-hire motor carriers. Whether that authority is currently in force is a separate question entirely. The registry tracks the lifecycle — granted, active, suspended, revoked, reinstated — and exposes the current state through the authority status field. Only one value clears a carrier to legally haul: ACTIVE.
An ACTIVE authority means the carrier has filed proof of insurance, designated a process agent, paid their registration fees, and has not been subject to a revocation or out-of-service order. It does not mean the carrier is reputable, financially solvent, or operating the equipment they claim. It means they are legally allowed to be on the road. Every other check — insurance, safety, equipment — sits on top of this baseline. If authority is not active, nothing else matters.
A carrier can have an active MC number and still be in the middle of an identity-flip scam, run lapsed insurance, or have a fleet on the OOS list. Active is the first gate, not the only one. Treat 'authority status: ACTIVE' as permission to keep verifying — not as a green light to tender.
Verifying an MC number is one of the fastest checks in carrier onboarding when you know exactly which fields to read. Most experienced brokers run this in under a minute on every new tender.
If all five line up, the MC number itself is clear. Move on to insurance, safety, and equipment. If any one fails, stop. There is almost always another carrier on the lane.
The authority status field is a short controlled vocabulary. Each value has a specific regulatory meaning, and brokers should be able to decode them without looking it up.
Carriers operating under a PENDING MC are operating without authority. Some new carriers will push to take a tender 'so we can prove revenue for the underwriting'. They cannot legally do that. A pending MC on a tender is a hard stop until the status flips to ACTIVE — and that flip can take days or weeks.
Active authority is binary — the carrier either has it or they do not. But two patterns turn an ACTIVE status into a flag for closer inspection, both of them invisible from the status field alone.
The first pattern is recent reactivation after multi-year dormancy. A carrier whose authority was granted in 2009, revoked in 2014, and reinstated in the last 60 days has an ACTIVE flag — but the operation behind the MC is brand-new. This is the textbook fingerprint of an identity-flip scam: someone purchased the dormant MC, refiled the paperwork, and is now soliciting freight under a carrier name with apparent history.
The second pattern is a populated future cancellation date on the underlying insurance filing. The MC stays ACTIVE until the cancellation actually fires, which can be 30 days after the notice was filed. Brokers who read only the authority status miss this. Brokers who read the BMC-91 cancellation date catch it.
Three patterns trip up dispatchers who only verify MC occasionally.
Knowhaul's carrier verification pulls the authority status, OOS date, authority type, and full authority history in a single query — same-day, no manual re-clicking. Reactivation-after-dormancy and identity-flip patterns are pre-flagged at the top of the card so they cannot be missed. For brokers running dozens of tenders a week, this is the difference between a per-carrier vetting workflow that takes 15 minutes and one that takes 30 seconds.
Negligent-selection lawsuits against brokers increasingly hinge on whether the broker can prove authority verification at the time of tender. A timestamped log of the authority read on the tender day is the strongest defense. Knowhaul writes that log automatically on every search.
Insurance-lapse revocations can fire automatically when the insurer files a cancellation notice with no superseding policy on file. The cancellation effective date is typically 30 days after the notice, but in some cases the authority can move to REVOKED status the same day. Treat any verification older than 24 hours as stale.
No. Authority status is independent of insurance. A PENDING authority is not authorized to operate, regardless of whether insurance has been filed. The carrier may be days away from ACTIVE status, but until the registry flips, they cannot legally haul interstate freight.
INACTIVE is a voluntary withdrawal — the carrier filed paperwork asking the regulator to deactivate their authority, usually because they shut down operations. REVOKED is involuntary — the regulator terminated authority for non-payment, insurance lapse, or compliance failure. For tender purposes, both mean the carrier cannot currently operate.
Most third-party carrier-database services pull from the federal registry on a 24-72 hour refresh cycle. The federal registry itself updates faster than that — sometimes within hours of a regulatory action. When two sources disagree, the federal registry is the source of truth. Use a tool that reads the registry live, not a cached snapshot.
Yes. The MC number itself is permanent — it is tied to the legal entity that filed for authority. A revoked authority can be reinstated by clearing the underlying cause (paying overdue fees, re-filing insurance, etc.). The MC number does not get reissued to a different carrier. This is the structural reason dormant-MC purchases work as an identity-flip vector — the buyer reactivates the existing MC under their control.
