Frequently Asked Questions
Common questions brokers and shippers ask about motor carriers in Seattle, Washington and how to vet them with FMCSA data.
How many trucking companies are based in Seattle, Washington?
There are roughly 25 FMCSA-registered motor carriers, brokers, and freight forwarders headquartered in Seattle. This includes large fleets with hundreds of trucks as well as owner-operators with a single power unit.
How do I vet a Seattle carrier before tendering a load?
Open the carrier's profile and review their operating authority, insurance status, safety rating, BASIC scores, and recent changes. The Broker Due Diligence checklist on each carrier page surfaces the specific flags brokers should review. Always request a fresh certificate of insurance directly from the carrier as a final step.
What does it mean if a Seattle carrier is "Inactive"?
Inactive operating status means the carrier's USDOT registration has lapsed, often because they failed to file the required biennial MCS-150 update. Inactive carriers are not authorized to operate and you should not tender loads to them without verifying current authority directly with FMCSA.
Are owner-operators in Seattle included?
Yes. Any FMCSA-registered carrier based in Seattle appears in this list, from single-truck owner-operators up to fleets with thousands of power units. Fleet size is one of the columns shown so you can scope your search accordingly.
How current is this list?
The list refreshes daily from FMCSA's Company Census File. New carriers appear as they register, and inactive carriers stay listed until FMCSA removes them from the dataset.
