Costco Wholesale Corporation (USDOT 589006, MC-1778380), doing business as Costco Wholesale, is an active motor carrier based in Issaquah, Washington that FMCSA's census classifies as for-hire and that declares hazardous materials on its MCS-150. Operation: interstate. Operating authority: active for-hire authority (MC). Fleet: 1,436 power units and 2,612 drivers (2,612 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. Its MCS-150 of June 25, 2026 reports 112,166,298 miles and gives 2026, the year it was filed, as the mileage year, so the figure is not a full calendar year's total. Cargo classes declared: chemicals, liquids / gases, dry bulk commodities, general freight, intermodal containers, building materials, construction, refrigerated food, fresh produce, beverages, paper products, household goods, meat, other cargo (other: Iep). It is also classified as a private carrier of its own goods. FMCSA has not issued it a safety rating (no compliance review on record). Registration (MCS-150) last updated June 25, 2026.
