Whether you've been notified of an upcoming ATF compliance inspection or you simply want to maintain a state of readiness, having a structured pre-inspection checklist is one of the most practical compliance tools an FFL can have. The following covers the primary areas ATF IOIs evaluate during a compliance inspection.
Form 4473 Review
Pull and review your Form 4473s for at least the past 12 months, or since your last inspection. Work through each form systematically:
- Section A: Buyer information complete, ID documented, all required fields filled
- Section B: All questions answered — no blanks, no ambiguous entries
- Section C: Buyer certification signed and dated on the correct date
- Section D: NICS transaction number recorded, proceed response documented, transfer date correct
- Section E: Transferor certification signed and dated, firearm description matches bound book
Look for pattern errors. If you find the same error on multiple forms — a consistently missing initial location, a section that employees regularly leave incomplete — that pattern is exactly what ATF will note in a Report of Violations. Fix the pattern, not just individual forms.
Bound Book Review
- All acquisitions entered within the required timeframe
- All disposals recorded with complete information including buyer name, Form 4473 date, and transaction type
- No missing serial numbers or incomplete firearm descriptions
- Bound book format meets ATF requirements for your license type
- Book is current — no backlog of unrecorded entries
Physical Inventory Reconciliation
- Count every firearm in inventory
- Reconcile against bound book — every firearm present should have an acquisition entry with no disposal
- Investigate any discrepancies before the inspection
- Document any known discrepancies with explanation
Unresolved inventory discrepancies are serious. If you cannot account for every firearm that appears in your bound book as acquired but not disposed, you need to resolve this before ATF arrives — and document your investigation thoroughly.
License and Posting Requirements
- FFL license is current and prominently posted at the licensed premises
- License address matches your actual business location
- Any required state licenses or permits are current and posted
- ATF-required buyer notices are posted at point of sale
Multiple Handgun Sales Reports
- All ATF Form 3310.4 (Multiple Handgun Sales) reports have been filed for qualifying transactions
- Reports were submitted within the required timeframe
- Copies of submitted reports are retained in your files
Employee Training Documentation
- Records of 4473 and compliance training for all employees who handle transfers
- Any corrective training following prior compliance issues is documented
Being organized is not just helpful — it's a statement. An FFL who can immediately produce organized records for any requested period signals to an IOI that compliance is taken seriously. This matters in how the inspection is conducted and how any violations found are characterized.
If ATF Arrives Unannounced
Stay calm. Verify the IOI's credentials. You can ask for a brief period — typically 15-30 minutes — to contact your attorney before the inspection begins, but you cannot indefinitely delay the inspection. Cooperate professionally, take notes on what is being reviewed, and request copies of any documents taken from your premises.
