The Industry Operations Inspector pulls a stack of Forms 4473 from the file cabinet, sits down at your desk, and starts going page by page. Within an hour they have a list of citations. Most of those citations are not for exotic compliance questions or edge-case interpretations — they are for the same handful of clerical errors that show up on inspection reports across the country every year. Here are the most common Form 4473 mistakes that get FFLs cited, and the discipline required to avoid them.

1. Incomplete Section B (Transferor/Seller)

Section B is where the dealer certifies the transfer. It includes the trade or corporate name, the address of the transferring location, the make, model, serial number, type, and caliber of the firearm being transferred, and the signature of the transferor. Inspectors find Section B errors constantly: the dealer name typed but the dealer signature missing, the address of the wrong location used (common in multi-location FFLs), or the firearm description copied from the wrong line item.

The fix is procedural — Section B should be filled out only after the transfer is complete and reviewed against the firearm in front of you, not pre-printed in advance.

2. Missing or Wrong Buyer Address

Section A requires the buyer's current residence address. The number one citation here: the address on the buyer's ID does not match the address they wrote in Section A, and there is no notation explaining the discrepancy. ATF accepts that an ID may have an old address — but only if the dealer documents the buyer's current residence address and notes the discrepancy on the form.

If the address on the ID is current and matches Section A, no notation is needed. If it does not match, write the current address in Section A and add a brief note (e.g., "Current address differs from ID; verified by [secondary document]"). Skipping the note is the citation.

3. NICS Information Not Recorded or Wrong

The NICS Transaction Number, the response, and the date of the response all have to be recorded on the form. Common errors: writing the NICS number but forgetting the date, writing "Proceed" without the transaction number, or leaving the section blank when a state Point of Contact (POC) was used instead of the federal NICS — and not filling out the equivalent state-level fields.

Every NICS-related field in Section C must be completed for every transaction, even the date. If a delayed response was eventually proceed-ed, the date you logged the proceed is the date that goes on the form, not the date of the original check.

4. Yes/No Questions Not Answered

Section A includes a list of yes/no questions covering felony history, restraining orders, drug use, citizenship, and similar disqualifiers. Inspectors find unanswered questions — usually because the buyer skipped one or skipped the entire question block — alarmingly often. An unanswered question is treated by inspectors as an incomplete form.

The dealer's job before submitting NICS is to confirm every yes/no box on Section A is marked. If even one is blank, hand the form back and have the buyer complete it. Do not initial it for them. Do not check "no" on their behalf.

5. Late Completion or Backdating

The buyer's date and the dealer's date have to reflect the actual day each section was completed. Backdating either field is a serious violation. Common scenario: a delayed transfer is finally proceed-ed three weeks after the buyer initially filled out Section A. The transfer is completed today, but the dealer dates Section B with the original Section A date so the form looks "consistent." That is backdating.

The correct approach: Section A is dated when the buyer completes it. Section B is dated when the dealer completes the transfer. The two dates can differ by hours or weeks; that is expected and correct.

6. Form 4473 Filed Out of Sequence

Forms 4473 must be filed by date or by an alphabetical/numerical scheme that the dealer has consistently applied. Inspectors expect to be able to find any form within minutes. The two acceptable systems are chronological (date order) or alphabetical (by buyer last name). Mixing systems, or refiling old forms in the wrong order after pulling them, is a citation under 27 CFR 478.124.

Pick a system on day one and never deviate. If you switch systems — for example, moving from chronological to alphabetical — document the change date and apply the new system from that date forward.

7. Mishandled Denials and Revoked Transfers

When NICS denies a transfer, the form is retained — not discarded. The form must be marked to reflect the denial and filed alongside completed transfers (or in a separate denial file as your written procedures specify). Inspectors find dealers who shred denial forms thinking the transaction "did not happen" and dealers who mark the form "DENIED" but file it where buyers might find it during walk-throughs.

Treat every started 4473 — even the ones that go nowhere — as a regulated record from the moment Section A is begun. Retain it. Mark it. File it. The retention requirements apply to denials and abandoned transactions just as much as to completed sales.

How Electronic Form 4473 Reduces These Errors

An electronic Form 4473 system that follows ATF Ruling 2016-2 will not let you submit a form with blank required fields, will lock buyer-completed sections before dealer review, and will time-stamp every entry so backdating is structurally impossible. The seven errors above are largely artifacts of paper forms and human attention. Software does not get tired and does not skip questions.
