BMC-91
BMC-91 is an FMCSA financial responsibility filing term that often appears when a carrier is activating or maintaining operating authority.

It is not a standard broker certificate. The filing is handled through the insurer or financial responsibility provider and should be checked through official FMCSA systems.
