1. Building a Bulletproof Vetting Workflow

Effective carrier onboarding requires a multi-layered verification strategy that combines real-time FMCSA regulatory checks with independent identity verification.

2. Top Fraud Prevention Strategies

Transportation professionals should implement the following security practices:

  • Independent Phone Verification: Never rely solely on phone numbers provided in inbound email signatures. Call the official phone number registered on the carrier's FMCSA file.
  • Email Domain Inspection: Verify that the dispatcher's email address matches the company's verified domain (e.g. check for lookalike domains with misspelled letters).
  • Recent Officer Changes: Check if the carrier underwent a rapid ownership or officer change within the last 30–60 days, which can sometimes signal an acquired dormant authority.
  • Consistent Equipment Records: Match the truck equipment type requested for the load against the cargo and vehicle classifications registered in the carrier's census.

Frequently Asked Questions

Why should brokers verify phone numbers on FMCSA records?
