FMCSA & Trucking Authority Glossary

FMCSA

The Federal Motor Carrier Safety Administration — the U.S. DOT agency that registers and regulates interstate trucking. FMCSA publishes its registration, authority and insurance records as public datasets, refreshed daily; that data is the source of everything on this site.

USDOT Number

The identifier every interstate carrier gets when it registers with FMCSA. A new USDOT number is the very first public trace of a new trucking company — it usually appears days to weeks before an application for operating authority.

MC Number (docket number)

The docket number assigned when a company applies for for-hire operating authority (MC for motor carriers, FF for freight forwarders, MX for Mexico-domiciled carriers). "New MC numbers" and "new authority applications" describe the same event: someone just asked FMCSA for permission to haul for hire.

Operating authority

FMCSA's permission to operate as a for-hire carrier, broker or freight forwarder. An application becomes granted authority once insurance and a BOC-3 are on file and the protest period passes — typically three to seven weeks after filing.

Authority granted

The decision date when a carrier may legally haul for hire. Freshly granted carriers have no established vendor relationships yet, which is why the grant date is the highest-value prospecting moment in trucking.

Authority pending (MC applied)

The window between application and grant. Pending carriers are lining up insurance, a process agent and equipment — the buying decisions are being made right now.

BOC-3 (process agent filing)

A designation of legal process agents in every state, required before authority can be granted. If a BOC-3 is withdrawn later, FMCSA suspends the authority until a new filing arrives — a fixable emergency for the carrier and a same-day sales opportunity for compliance services.

Insurance filing (BMC-91 / BMC-91X)

Proof of public-liability coverage that an insurer files directly with FMCSA. A new filing on a pending application signals the grant is close; a replacement filing on an active carrier usually means they just switched insurers.

Insurance cancellation notice

Insurers must notify FMCSA roughly 30 days before terminating a carrier's filed policy. During that window the carrier must replace coverage or lose authority — making cancellation notices the most time-sensitive lead in the dataset. Full guide →

Reinstatement

A previously revoked or suspended authority restored to active status — usually after new insurance or a new BOC-3 is filed. Reinstated carriers just bought something to get back on the road, and often need more.

X-date (renewal date)

Insurance-industry shorthand for the expiration date of a carrier's current policy — the one time each year they'll seriously consider switching agents. Public FMCSA filings show each policy's effective date, so the anniversary can be estimated; AuthorityAlerts surfaces carriers entering that window about 45 days out as the renewal window stage.

New Entrant

A carrier in its first 18 months of interstate operating authority, monitored under FMCSA's New Entrant Safety Assurance Program and required to pass a safety audit during that period. New entrants are the companies making their first insurance, factoring, ELD and compliance decisions — exactly the carriers AuthorityAlerts surfaces the day they appear in the data.

For-hire vs. private carrier

For-hire carriers haul other people's freight for compensation and need operating authority; private carriers haul only their own goods and generally don't. AuthorityAlerts tracks the for-hire universe — the companies that buy insurance, factoring, dispatch and compliance services.

Freight broker

A licensed middleman that arranges transportation without operating trucks, required to carry a $75,000 surety bond (BMC-84) or trust (BMC-85). New broker authorities are prospects for bond producers and factoring companies' broker programs.

Freight forwarder

An entity that consolidates shipments and assumes carrier-like responsibility for them. Forwarders hold FF authority with their own insurance requirements.

Filing agent (registration service)

A company that files FMCSA paperwork on a carrier's behalf. When an agent handles the registration, the contact details on the public record are often the agent's, not the owner's. AuthorityAlerts detects these across the whole dataset and flags them, so you know before you dial whether the number reaches the carrier or their paperwork service.
