Onboarding a Michigan carrier uses the same federal packet as anywhere else — the differences are intrastate registration, the insurance limits shippers in the state expect, and the lanes the carrier will actually run out of Detroit.
This page covers the MI-specific parts and the standard packet they sit on top of.
The federal packet, unchanged in Michigan
Interstate authority is federal. A MI carrier hauling across state lines is governed by FMCSA, so the documents you collect are identical to any other state.
- Signed dispatcher-carrier or broker-carrier agreement
- W-9 matching the carrier's legal entity and EIN
- FMCSA operating authority letter, active status confirmed
- Certificate of insurance — $1,000,000 auto liability, $100,000 cargo is the usual floor
- Voided check or bank letter, plus a notice of assignment if they factor
- Driver CDL and medical card
What is specific to MI
A carrier operating only within Michigan may hold intrastate authority from the state rather than an MC number, which changes what you are verifying — state registration instead of FMCSA authority. Confirm which one applies before you accept the load.
Practically, most MI carriers you onboard are running interstate lanes out of Detroit, Grand Rapids, Lansing, with Detroit to Toronto crossings as a common first route. Their insurance and authority will be federal.
- Confirm interstate authority versus Michigan intrastate registration
- Verify the carrier's principal place of business matches the MI address on file
- Check UCR registration is current for the year
- Match the entity name across the W-9, COI, and authority letter
Keeping a Michigan carrier compliant after onboarding
The two documents that go stale are the certificate of insurance and the authority status behind it. Set a renewal reminder thirty days before the policy date and re-check authority weekly for carriers you actively dispatch.
CarrierLeads tracks both automatically for every carrier in your vault, alongside the fresh MI authority feed you source new carriers from.
How we source this
Primary federal sources
Authority, insurance and safety facts come from FMCSA registration data, the Licensing & Insurance system, and the QCMobile API — not resold list files.
Refreshed weekly
Our ingest re-pulls new and re-filed authorities every week, then re-checks status before a record is ever shown or emailed.
Written from operating experience
Sequence structure, timing and copy guidance reflect the outreach we run inside the product from members' own mailboxes, under CAN-SPAM and TCPA constraints.
Verify any single carrier yourself with our free USDOT authority lookup, which queries the federal record live.
Frequently asked questions
- What documents do I need from a Michigan carrier?
- The standard federal packet: signed agreement, W-9, FMCSA authority letter, certificate of insurance, voided check or bank letter, notice of assignment if they factor, and the driver's CDL.
- Do Michigan carriers need an MC number?
- For interstate freight, yes. A carrier hauling only within Michigan may operate on state intrastate registration instead, which you verify with the state rather than FMCSA.
- What insurance limits do MI shippers expect?
- $1,000,000 auto liability and $100,000 cargo is the common baseline. High-value and temperature-controlled freight frequently require more.
- How fast can I onboard a Michigan carrier?
- Same day is realistic if you send one packet link during the call rather than emailing documents one at a time.
