How long does a BOC-3 stay on file with FMCSA?
Indefinitely — the BOC-3 is a lifetime designation tied to your MC/USDOT, not a recurring registration. Once filed, it stays on file with FMCSA until you change process-agent providers, change legal name or operating-authority entity, change MC number, or surrender the authority.
FMCSA Form BOC-3 is filed once per MC. The L&I system stores the designation under your USDOT/MC pair and the SAFER snapshot reflects the process-agent name as long as the BOC-3 is current. There is no FMCSA-side expiration date and no annual reconfirmation requirement.
The four events that supersede or void a BOC-3 are: (1) filing a new BOC-3 with a different process-agent provider — the new one replaces the old, (2) a legal-name or DBA change on the underlying MC — the old name on the BOC-3 no longer matches the carrier of record, (3) an MC-number change after revocation and re-application — the old BOC-3 was tied to the old MC, and (4) voluntary surrender of operating authority — the underlying authority disappears and the BOC-3 has nothing to attach to.
A common misconception is that a BOC-3 expires after a fixed number of years. It does not. Some commercial process-agent providers bill annually for their service, but the billing is the provider's subscription model — not an FMCSA-required renewal. The federal filing itself is one-and-done.
A BOC-3 carrier with a deactivated MC (revoked, voluntarily out-of-service for an extended period) typically files a fresh BOC-3 at reactivation. See /for-reactivating-mc for the reactivation-specific flow.
