Can I get a DOT number without a truck?

Yes—FMCSA lets you reserve a USDOT number even before you buy a truck.

In the Unified Registration System choose “0” power units and the number activates once the free application is processed. Update the MCS-150 later when equipment arrives.

Early filing helps new carriers and brokers lock in a name, arrange insurance, BOC-3 and UCR, yet you can delay MC authority and liability coverage until the vehicle is ready.

Just keep biennial updates current or the number can be deactivated for inactivity.
