Who can file a BOC-3 with the FMCSA?

A motor carrier must have a process agent - usually a blanket company on FMCSA's process-agent list - file its BOC-3; a carrier cannot designate itself. Filings are submitted electronically (Motus, which replaced the legacy URS system in May 2026).

How long does BOC-3 filing take?

Electronic BOC-3 filings are submitted to FMCSA promptly once the order is in and typically shown in FMCSA’s Motus public search within about one business day. Once accepted, the designation shows on the carrier’s record in FMCSA’s Motus public search and counts toward MC authority activation under 49 CFR §365.107.

What information is required on Form BOC-3?

Form BOC-3 requires the carrier's legal name, USDOT or MC number, principal place of business address, and the name and physical street address (no PO boxes) of each designated process agent per state, per FMCSA's Form BOC-3 page.

Why do BOC-3 filings get rejected?

Common BOC-3 rejection reasons include: (1) self-filing attempt by the carrier instead of through a process agent, (2) PO box used in place of a physical address, (3) MC number not yet issued by FMCSA, (4) mismatched legal name between BOC-3 and MCS-150, and (5) missing states for nationwide operations.

How much does a BOC-3 cost?

The FMCSA charges no fee for the BOC-3; some providers charge a yearly fee (for example $25 a year) and others a one-time fee, based on prices checked Oct 23, 2026. The FMCSA itself charges no filing fee for the BOC-3 - the cost is entirely the process agent's service fee. FastBOC3 Filing charges $75 flat, one-time - lifetime coverage in all 50 states plus D.C., fast BOC-3 filing, and a refile-or-refund guarantee, with no annual renewal.

How do you file a BOC-3?

Q: How many process agents do I need?

It depends on the type of authority. Under the operative rule, 49 CFR §366.4T, a motor carrier must designate an agent for each state in which it is authorized to operate and for each state it traverses, and a broker for each state in which its offices are located or in which contracts are written. Interstate operators therefore need a designated process agent in every state where they operate or accept loads - most use a blanket agent service covering all 50 states plus DC.

To file a BOC-3, a motor carrier hires a process agent, usually a blanket company on FMCSA's list, which files Form BOC-3 electronically for every required state. You need your legal name, USDOT number and MC or FF number. One BOC-3 can be on file at a time.

The Form BOC-3 lists your legal name, USDOT and MC number, and an agent with a street address in every required state, and the agent files it through FMCSA's Motus registration system (which replaced URS in May 2026). Intrastate-only carriers that don't need FMCSA operating authority don't file a BOC-3 at all. Your BOC-3 is filed soon after you order, and it usually shows on FMCSA's record within about one business day. FMCSA charges no fee for the BOC-3; you pay the agent's service fee, once or yearly depending on the provider (FastBOC3 is $75 once; compare prices).

How do I file a BOC-3 for a new trucking company?

A new trucking company gets its BOC-3 filed in four steps.

1.Get a USDOT number and apply for MC authority in Motus.
2.Choose a process agent, usually a blanket company.
3.Give the agent your legal name, USDOT and MC numbers.
4.The agent files Form BOC-3, due 20 days after your FMCSA Register notice (49 CFR 365.109T).

Filing the BOC-3 doesn't activate your authority by itself: FMCSA also needs your insurance filing, and FMCSA decides when the authority goes active. The details of each step are below, and BOC-3 for a new MC number covers the timing.

Updated for Motus - FMCSA's New Registration System (May 2026)

FMCSA has retired its legacy URS registration flow. The replacement, Motus, opened Phase I to new applicants on December 8, 2025; legacy systems were retired on May 14, 2026 and Motus opened to all users on May 19, 2026. Motus now handles FMCSA registration end to end, with identity verification through Login.gov.

For the BOC-3, nothing changes on your side: the filing is still submitted by the process agent, through the agent's own Motus account - carriers cannot file it inside their own Motus registration. Your steps are the same as before: file your BOC-3 online for $75, and it is filed promptly after you order (once your MC or FF number is issued). For a portal-specific walkthrough, see how to file a BOC-3 in Motus.

Who can file the BOC-3

Motor carriers must have a process agent (usually a blanket company) file the BOC-3 for them; a carrier cannot designate itself. Designations are filed electronically (through Motus as of May 2026, replacing the legacy URS system), so a paper BOC-3 someone mails or emails you to send in is not how the filing gets made.

How many process agents you need

Under the operative rule, 49 CFR §366.4T, the number of designated process agents depends on operational scope: a motor carrier designates an agent for each state in which it is authorized to operate and for each state it traverses, and a broker for each state in which its offices are located or in which contracts are written. Interstate motor carriers and freight brokers need an agent in every state where they pick up loads, deliver, or accept service of process. Most carriers use a blanket nationwide service that designates an agent in all 50 states plus the District of Columbia in a single filing.

Required information on Form BOC-3

The BOC-3 must list the carrier's legal name as registered with FMCSA, USDOT and MC numbers, principal place of business, and the full name and physical street address of each designated process agent. PO boxes are not accepted (FMCSA Form BOC-3 page) - the agent must have a real, staffed street address where legal papers can be served during normal business hours.

Common BOC-3 rejections

Common rejection reasons include a carrier attempting to self-file instead of going through an agent, a PO box used in place of a street address, the MC number not yet issued by FMCSA at the time of filing, the legal name on BOC-3 not matching the name on the MCS-150, and missing states for nationwide operations. A rejected BOC-3 has to be corrected and refiled before your authority can activate, which is why most carriers hand the BOC-3 filing to a designated agent. The rejection causes guide covers the fix for each.

Filing for new authority: what to have ready, and what happens next

Before the BOC-3 can be filed you need two things: a USDOT number (registration in FMCSA's Motus system is free), and an operating-authority application on file with FMCSA - an MC number for carriers and brokers, FF for freight forwarders, MX for Mexico-domiciled carriers. You don't have to wait for the authority to be granted. FMCSA expects the BOC-3 within 20 days of your application notice in the FMCSA Register (49 CFR 365.109T(a)(6)), so filing early is the safer order.

The process agent will ask for your legal business name exactly as it appears on your USDOT record (plus any DBA), your USDOT number and docket number, your business address, and your authority type.

Once filed, the BOC-3 is one of the filings FMCSA needs before it activates your authority. The other is proof of financial responsibility - your insurer's filing for a carrier, or the $75,000 bond or trust for a broker. Authority moves from pending to active only when every required filing is on record. What to check at that point is covered in what to file after your MC number is issued and how to check your BOC-3 status.
