DOT numbers are 7–8 digits. MC numbers may include or exclude the "MC" prefix.

Why Verify a Carrier Before Tendering a Load

Freight brokers are legally required under FMCSA regulations to verify that carriers have active operating authority and adequate insurance before tendering freight. Failing to do so exposes brokers to liability if a carrier causes damage or an accident.

Even for shippers working directly with carriers, checking FMCSA status takes 30 seconds and catches problems before they become expensive: uninsured carriers, revoked authority, or carriers with poor safety records that could lead to cargo damage or delayed delivery.

Frequently Asked Questions

What is a DOT number in trucking?

A USDOT number is a unique identifier assigned by FMCSA to commercial motor carriers. All carriers operating commercial vehicles in interstate commerce are required to have one. It's used to track safety records, compliance, and crash data.

What is an MC number in trucking?

An MC number is an operating authority number required for for-hire carriers hauling regulated commodities in interstate commerce. Active MC authority is required before a broker can legally tender a load. Not all carriers with a DOT number have an MC number.

What does active authority mean for a carrier?

Active authority means the carrier's FMCSA operating authority is current and valid. Authority can be revoked for safety violations, insurance lapses, or non-compliance. Always verify authority status is active before tendering a load.

Is the FMCSA carrier lookup data real-time?

The FMCSA SAFER database is updated daily from a 24-hour old source. For time-sensitive decisions, verify directly at safer.fmcsa.dot.gov. Authority status and insurance filings update as carriers file changes with FMCSA.
