MC Number Registration Process

An MC number is required for motor carriers transporting regulated property or passengers in interstate commerce. Different from DOT number.

Who needs MC number

For-hire interstate motor carriers
For-hire interstate passenger carriers
Brokers/freight forwarders (also Property/Household Goods)

Who does NOT need MC number

Intrastate carriers (state authority only)
Private (not-for-hire) carriers (DOT number sufficient)
Some specialized exemptions (agricultural, etc.)

Application steps

Obtain a DOT number (free, instant via FMCSA)
Submit OP-1 application (or OP-2 for broker)
Pay $300 application fee
Establish insurance (BMC-91 + BMC-91X if applicable)
Designate process agents in each state of operation (BOC-3)
Wait for review (30-60 days typical)
MC number issued

Required documents

Form OP-1 (or OP-2)
Form BOC-3 (process agents)
Form BMC-91 (insurance proof)
Form BMC-32 (cargo insurance, if applicable)
USDOT registration (already required)
Process agent agreements (per state)

Common issues

Application errors → return to applicant
Insurance not filed correctly → delay
Process agents not designated → delay
Fees not paid → delay

Maintenance

Annual update of MCS-150 (carrier info update)
Insurance must remain current
Process agent agreements maintained
Annual fees (if any) paid

Renewal vs maintenance

MC numbers don't expire if maintained
Failure to maintain → revocation
Reinstatement possible (but costs + time)

Compass authority module
