# DOT number vs MC number

A USDOT number identifies your company for safety. An MC number gives you authority to haul regulated freight for hire across state lines. Many carriers need both.

## Side by side

|  | USDOT number | MC number |
| --- | --- | --- |
| What it is | Safety identifier for a company | Docket number for operating authority |
| Who needs it | Interstate CMV operators and many intrastate carriers | For-hire carriers of regulated commodities across state lines, plus brokers and forwarders |
| Cost | Free | FMCSA fee per authority type |
| Ongoing | MCS-150 update every 24 months | Insurance and BOC-3 must stay on file |

## Which do you need?

-   Private carrier hauling your own goods across state lines: USDOT number
-   For-hire carrier hauling customer freight across state lines: USDOT number and MC authority
-   Freight broker: MC (broker) authority plus a surety bond or trust
-   Intrastate only: check your state's rules, many states require a USDOT number
