Form MCS-150 PDF Details

FMCSA encourages all applicants with Internet access to use its online registration site to determine all FMCSA registration requirements.

Reason for filing: Select one of the four reasons and mark its corresponding box at the top of the form under Reason for Filing.

Rejection: Applications that are incomplete, unreadable, or unsigned will be rejected and returned via mail, delaying the receipt of the company's USDOT Number.

Hazmat Shipper only: If you select only Hazmat Shipper (no carrier operation) from the list, the company is not required to obtain a USDOT Number, so no filing is needed.

Mail processing: Mailed applications, on average, take four to six weeks processing time.
