The 49 CFR §366 framework lets carriers designate process agents either state-by-state (single-state) or through a blanket service that covers every state in a single filing. The federal rule requires an agent in every state where the carrier operates. For a long-haul interstate carrier that means all 48 contiguous states plus often Alaska and Hawaii. Filing 50 separate single-state designations is technically possible but almost no one does it.
Blanket coverage works because federal regulations explicitly permit a carrier to use "blanket" service through one designated provider. The provider has agents in every state and the carrier files a single BOC-3 listing the provider's name and address.
Side-by-side comparison
| Attribute | Single-State | Blanket (All-State) |
|---|---|---|
| Coverage | One state listed on the filing | All 50 states + DC |
| Number of BOC-3 filings required | One per state of operation (potentially 50) | One |
| Typical cost | $50–$200 per state per year (recurring) | About $75 one-time |
| Best fit for | Intrastate carriers operating in only one state (rare for interstate) | Every interstate motor carrier, broker, or freight forwarder |
| Activation friction | High - requires confirming each state filing is on record before authority activates | Low - single filing posts to FMCSA L&I, authority activates on schedule |
| Risk if you operate in additional states | Authority becomes invalid in any unlisted state - out-of-service exposure | Already covered nationwide |
| Renewal | Generally annual per state per agent contract | One-time; only refile on legal-name or agent change |
| Most common new-carrier mistake | Picking single-state to save money, then expanding without refiling | Confusing blanket coverage with state registered-agent requirements |
When to choose each
When to choose Single-State
Niche intrastate operators that only run in one state
If your operation will never cross a state line - and you have no plans to apply for MC authority - single-state coverage may suffice. Most carriers are interstate at some point; single-state is rarely the right choice.
When to choose Blanket (All-State)
Every interstate motor carrier, broker, and freight forwarder
Blanket service is the standard for almost every for-hire carrier. One filing, one fee, coverage nationwide. Use FastBOC3Filing for blanket coverage filed within two hours.

Frequently asked questions
If I run in only three states, do I need blanket coverage?
Technically no - the regulation requires designation only in states where you operate. Practically, blanket coverage costs less than three single-state filings and protects you when a load takes you into a fourth state.
Does blanket coverage protect me in Canada or Mexico?
No. The BOC-3 is a US federal filing. Cross-border operations have separate process-agent requirements under each country's motor carrier statute.
How quickly can FMCSA process a switch from single-state to blanket?
Same business day in most cases. The new BOC-3 supersedes the previous one upon FMCSA acceptance.
Will FMCSA reject my MC application if I have only single-state coverage and run nationwide?
Yes - FMCSA verifies that the BOC-3 covers the states where you have indicated operations. A mismatch will hold the docket in pending status.
Can I cancel a blanket BOC-3?
You can - but only by filing a new BOC-3 designating a different agent. Withdrawing a BOC-3 without replacing it deactivates your MC authority.
