Freight brokers onboard a new carrier by collecting a setup packet (signed broker-carrier agreement, W-9, and certificate of insurance), confirming active operating authority and insurance in FMCSA records, and verifying contact and payment details through a channel the broker already trusts. Any mismatch stops onboarding until a person resolves it.
Start with a complete setup packet
A carrier is not ready to haul your freight until the paperwork is in one place. Ask for the same packet from every carrier, every time. A consistent packet makes gaps easy to spot.
Carriers often send documents piecemeal across several emails. Keep a checklist so nothing slips through while loads wait.
Name one person who owns each onboarding. When everyone assumes someone else checked the insurance, nobody did. A short sign-off line on the checklist, with a name and a date, fixes that.
- Broker-carrier agreement, signed by an authorized person at the carrier
- Form W-9, which gives you the carrier's taxpayer identification number for tax reporting
- Certificate of insurance showing auto liability and cargo coverage, with you listed as certificate holder
- Copy of operating authority, with the USDOT number and MC number if one applies
- Remit-to and payment details, plus a dispatch contact and an after-hours number
Check operating authority and insurance in FMCSA records
Do not rely on the documents the carrier sends. Look the carrier up yourself in FMCSA records. The authority fields show whether the entity is registered as a common carrier, contract carrier, or property broker. An Active status means the carrier is registered and has complied with the applicable insurance rules.
The same records list insurance on file: the form, the insurer, the policy number, the coverage amount, and the effective date. Compare these to the certificate of insurance. If the certificate shows coverage that FMCSA records do not, stop and ask why.
Check the minimums too. For general freight in vehicles over 10,001 pounds, the federal minimum for auto liability is $750,000. Insurers file proof of that coverage with FMCSA on a BMC-91 or BMC-91X, with an MCS-90 endorsement. Federal rules do not require cargo insurance for most freight, so set your own cargo minimum in your agreement.
Also check the dates. A certificate that expires next week is a problem you will own in seven days. Note the expiration date in your records on day one.
Confirm contact details through a known channel
Your next job is to prove the person you are emailing is the carrier. Take the phone number listed in FMCSA records, not the one in the email signature or on the packet. Call it and speak to someone who can confirm they sent the paperwork.
The company name, address, and phone number should match what FMCSA shows. FMCSA has warned that unauthorized entities use another motor carrier's assigned USDOT number to take loads. A mismatch is a reason to pause, not a typo to wave through.
Write down who you spoke to, the number you called, and the date. That note is your proof later if a payment dispute comes up.
If nobody answers or the number is disconnected, do not fall back on the number in the email. Wait, try again, and escalate to a second person. A real carrier will call you back.
Verify payment information separately
Payment details are the highest-risk part of the packet. Confirm the remit-to account, factoring arrangement, or payment address on a call to a number you already verified. Do not confirm by replying to the email that contained the details.
Ask a person on the carrier side to read the details back. Keep the first payment small in your own process if the carrier is new to you, and have a second person approve any payment-detail change.
Write the rule into your process so it does not depend on who is working that day. Payment changes get a callback, every time, no exceptions for a busy Friday.
Red flags during setup
Most bad actors give themselves away in small ways. Treat any one of these as a reason to slow down, and several together as a reason to stop. FMCSA's guidance points to false identities, blind loads, and unusually high rates as signs to halt a transaction.
- Contact details that do not match FMCSA records
- A free email domain, or a domain that looks almost like the real carrier's
- Pressure to skip a step or get on a load right now
- Insurance certificate that does not match insurance on file
- Payment instructions that arrive late or change after approval
Keep records current after setup
Onboarding is not a one-time event. Insurance lapses, authority changes, and contact details drift. Set a recurring check for every active carrier, and re-verify insurance before each policy expiration date.
Recheck FMCSA status before you tender a load to a carrier you have not used in a while. Treat any later change to bank or remit-to details as a new verification: call the verified number again before you update anything.
