A rejected BOC-3 almost always comes back to a data problem or a timing problem: the legal name, USDOT or MC number on the filing doesn't match FMCSA's record, or the authority it is filed against isn't issued or active. This guide doesn't list official code numbers; the causes below are described in plain terms, with the fix for each. Your process agent can tell you the exact reason text it received. For the wider list of avoidable errors, see common BOC-3 mistakes, and for what happens to your order, see what if my BOC-3 is rejected?
1. The legal name doesn't match FMCSA's record
The BOC-3 name has to match the legal entity name on FMCSA's record character-for- character. The usual mismatches are punctuation differences (LLC vs L.L.C., comma-before-LLC), trailing words (Inc, Incorporated, Corp, Corporation), and DBA suffixes appended to the legal name. Fix: pull your USDOT record from SAFER, copy the legal name exactly as displayed, and submit the BOC-3 with that string. If the record itself is wrong, file an MCS-150 update first, then refile the BOC-3 once the corrected name shows.
2. The authority isn't issued yet
The BOC-3 can't attach to an authority record that doesn't exist yet, so a filing made before FMCSA has issued your MC number won't go through. Fix: wait until your MC number is issued (it appears on your SAFER record once FMCSA issues it), then refile. The post-MC sequence is covered in what to file after your MC number is issued.
3. The USDOT number is wrong
Either the USDOT number doesn't exist or it doesn't belong to the named entity. Most often this is a typo, such as a transposed digit. Fix: verify the number on SAFER and resubmit with the correct value.
4. The process agent isn't registered in a state
This happens when a blanket provider files a BOC-3 that lists a state where its network has lapsed or was never registered. Fix:this is the provider's problem to correct, not yours. The provider should resubmit with corrected coverage; if it can't, a new BOC-3 with a provider whose network is current replaces the old one (see process agent quit or BOC-3 withdrawn).
5. A matching BOC-3 is already on file
A duplicate notice means a BOC-3 is already on file for this authority and the new submission is identical to it. The existing filing is intact. Fix: confirm on SAFER that your authority is active, and treat the duplicate notice as a no-op.
6. The operating authority is revoked
A BOC-3 filed against revoked authority has no active authority record to attach to. This usually surfaces when a carrier whose authority lapsed (often for an insurance gap) files a BOC-3 hoping to reactivate. Fix: reinstate the underlying authority first, which usually means refiling insurance via BMC-91 or BMC-34 and curing whatever caused the revocation. Once authority is reinstated, the existing BOC-3 may still be on file (see BOC-3 after authority reinstatement); if not, refile.
7. The form is incomplete
Missing fields, such as a missing physical address or a partial state list, stop a filing. With a blanket provider that is a clerical error on the provider's side. Fix: ask the provider to refile with the complete record.
8. The address disagrees with your MCS-150
A filing can be flagged when the address on the BOC-3 is a different physical address from the one on your MCS-150. Formatting differences (suite numbers, capitalization) are not the issue; an outdated address on the carrier record is. Fix: file an MCS-150 update with the current address, wait for SAFER to show it, then refile the BOC-3.
How you find out about a rejection
Rejection notices go to the process agent that filed the BOC-3, not to the carrier directly. If your authority status on SAFER still reads NOT AUTHORIZED when you expected it to be active, ask your provider for the FMCSA response; it names the reason. Then check your USDOT record for anything that needs an MCS-150 update, since many rejections trace back to a stale carrier record rather than the BOC-3 itself.
FastBOC3's Refile-or-Refund Guarantee
FastBOC3 includes a refile-or-refund guarantee on every $75 filing: if FMCSA rejects your filing because of an error on our side, it is refiled free, and if it still can't be fixed, we refund your $75. It doesn't cover rejections caused by information you supplied, such as a legal name that doesn't match your FMCSA record, which is why those details are checked when you order.
Bottom line: Most BOC-3 rejections come down to a name mismatch or a timing issue with the underlying authority. Fix the upstream record, then refile. Order a $75 BOC-3 with a refile-or-refund guarantee.
