Most FFL dealers have never been through a compliance inspection and have little sense of what actually happens when an ATF Industry Operations Inspector arrives. Understanding the inspection process — what they look at, in what order, and what they're trying to determine — helps dealers focus their compliance efforts where they matter most.
The Opening Conference
A compliance inspection typically begins with an opening conference where the IOI introduces themselves, presents credentials, explains the purpose and scope of the inspection, and outlines the process. This is an opportunity to ask questions and establish a professional working relationship. Dealers who approach this conference with a cooperative, professional attitude set a positive tone for the entire inspection.
License Verification and Posting
The IOI will verify that your license is current, that it is posted appropriately at the licensed premises, and that the address on the license matches your actual business location. They will also verify that all required responsible persons are correctly listed on the license.
Bound Book Review
The A&D bound book is one of the first substantive documents reviewed. The IOI is looking for: all required entries present, acquisitions and dispositions recorded promptly, complete information in every entry, and internal consistency. They will typically select a date range and review all entries within that period, then cross-reference against other records.
The bound book sets the scope for 4473 review. The IOI often uses the bound book to identify which transfers occurred during the review period, then pulls the corresponding Form 4473s to verify each disposal entry. A clean bound book with consistent disposal entries makes the 4473 review process faster and less adversarial.
Form 4473 Review
The 4473 review is typically the most time-consuming part of the inspection. The IOI works through each form in the review period section by section. They are looking for: complete and legible entries in every required field, proper signatures and initials in all required locations, NICS transaction numbers and proceed results documented, and transfer dates that are consistent with NICS check dates and bound book disposal dates.
The IOI will note each deficiency on their working papers. At the end of the review, they will typically compile and review their findings to determine which are citable violations and how many forms are affected.
Physical Inventory
Physical inventory reconciliation involves counting the firearms in your possession and reconciling that count against your bound book. Every firearm present should appear as an acquisition with no disposal. Every acquisition without a disposal should be physically present. Discrepancies are investigated.
Unexplained inventory discrepancies are serious findings. An IOI who finds a firearm in your inventory with no bound book entry, or a bound book entry for a firearm that is not in your inventory and has no disposal record, will treat this as a significant finding regardless of how clean the rest of your records are.
Multiple Handgun Sale Reports
The IOI will review your records for transactions that should have triggered a Form 3310.4 filing and verify that corresponding reports were timely submitted. Missing or late 3310.4 filings are commonly cited violations that are relatively easy for the IOI to identify by comparing bound book disposals.
The Closing Conference
At the conclusion of the inspection, the IOI will typically conduct a closing conference to review their preliminary findings with you. This is an important moment — it is your opportunity to provide context, correct factual misunderstandings, and understand what will be in the report. Take notes. Ask for clarification on any finding you don't understand. The closing conference often shapes how violations are characterized in the final report.
