FMCSA/MCS150 Biennial UpdateOn August 23, 2013, FMCSA published a final rule, Unified Registration System (URS), amending its regulations requiring interstate motor carriers, freight forwarders, brokers, intermodal equipment providers (IEPs), hazardous materials safety permit (HMSP) applicants, and cargo tank facilities under FMCSA jurisdiction to submit required registration and FMCSA/MCS150 biennial update information to the Agency using a new electronic on-line Unified Registration System (URS).

The implementation of the URS final rule consolidates the following registration and information systems:

The U.S. Department of Transportation (USDOT) identification number system;

The commercial registration system to obtain for-hire operating authority/MC Number;

The financial responsibility information system; and

The service of process agent designation system.

Effective November 1, 2013:

The MCS-150 form is being replaced by the online registration MCSA-1 form.

You may request a pin or make a request for a forgotten pin using this link FMCSA PIN#

All new USDOT applicants and entities required to submit a biennial update will be required to complete their update online using the MCSA-1 form.  (Refer to biennial update schedule below).

FMCSA will issue a warning letter 30 days prior to your biennial update deadline.

Failure to file an update will result in inactivation of your USDOT Number and you will be prohibited from operating.

If you change your legal company name, form of business or address, you must notify FMCSA within 30 days.
