ATF Compliance Inspection Guide

• Compliance inspection. The standard, routine inspection. The IOI reviews your records for completeness and accuracy, conducts a physical inventory check, and verifies that your operation matches your license. This is what most FFLs experience.
• Application inspection. Conducted when you first apply for an FFL or when you renew. The IOI visits your proposed premises, verifies your physical location, reviews your security setup, and conducts an in-person interview.
• Trace inspection. Triggered when the ATF needs to trace a specific firearm, typically one recovered at a crime scene. The IOI will ask to see the A&D records and Form 4473 for a specific serial number. These are usually quick and narrowly focused.
• Follow-up inspection. Conducted after a previous inspection identified violations. The IOI returns to verify that you have corrected the issues. Follow-ups are typically scheduled and announced.

A standard compliance inspection covers four primary areas. Understanding what is being checked is the foundation of being prepared.

1. ATF Form 4473 records. The IOI will pull a sample of your completed 4473s and review them for completeness, accuracy, and proper execution, checking that:

• All required fields are completed, with no blanks.
• Buyer information matches the identification presented.
• All eligibility questions are answered.
• Signatures and dates are present in all required sections.
• The NICS transaction number, response, and date are recorded.
• The firearm description matches the A&D entry.
• The current form revision is in use.
• Denied and non-completed forms are properly retained.

The sample size depends on your transaction volume. High-volume dealers may have a hundred or more forms reviewed. Smaller operations may have every form from the past year examined.

2. Acquisition and disposition records. Your A&D book is cross-referenced against your 4473 files and your physical inventory. The IOI checks that every firearm in your physical inventory has a corresponding acquisition entry, every disposition entry has a corresponding 4473 for non-licensee transfers, serial numbers match across all records, entries are timely, and the manufacturer or importer is recorded correctly rather than just the brand name. See the A&D book guide for the full requirements.

3. Physical inventory. The IOI will count firearms on your premises and compare the count to your A&D book. Firearms present without entries, or entries without corresponding firearms, are inventory discrepancies, one of the most serious findings an inspection can produce. Missing firearms with no disposition record are treated as potential diversions, and multiple missing firearms can trigger a criminal referral.

4. Multiple sale reports. The IOI cross-references your A&D records to identify instances where the same buyer received two or more handguns within five consecutive business days. If those transactions exist without a corresponding Form 3310.4, that is a finding.

Compliance inspections are mandatory. You cannot refuse one and keep your license. But you do have rights:

• Business hours only. The ATF can only conduct inspections during your normal business hours.
• Scope limitation. The inspection is limited to firearms records, inventory, and premises. The IOI cannot search your personal vehicle, your home unless it is your licensed premises, or records unrelated to your firearms business.
• One routine inspection per year. Under 18 U.S.C. 923(g)(1)(B), the ATF is limited to one compliance inspection per 12-month period. Trace inspections, criminal investigations, and follow-ups do not count toward this limit.
• You can have an attorney present. You are not required to, but you have the right.
• You can ask for identification. Verify the IOI's credentials before providing access to your records.
• You can take notes. Document what the IOI reviewed, what questions were asked, and what findings were discussed.

Cooperate fully, be professional, and do not volunteer information that was not asked for. Answer questions directly. If you do not know the answer, say so rather than guess. Making the process smooth and organized works in your favor.

ATF inspection data consistently shows the same categories of violations year after year. These are not obscure technicalities, they are the basics. Form 4473 errors account for seven of the top ten ATF compliance findings.

Form 4473 violations:

• Missing or incomplete buyer information.
• Blank eligibility questions.
• Missing signatures or dates.
• NICS documentation failures, such as no transaction number or no response recorded.
• Serial number mismatches between the 4473 and A&D book.
• Using an outdated form revision.

A&D record violations:

• Missing acquisition entries, meaning firearms in inventory with no record.
• Missing disposition entries, meaning no record of where a firearm went.
• Late entries.
• Incomplete entries missing the manufacturer, caliber, or source information.
• Serial number transcription errors.

Other common findings: inventory discrepancies, missing Form 3310.4 reports, operating outside license scope, failure to report theft or loss within 48 hours, and improper storage of records away from the licensed premises.

No violations found. The IOI completes the inspection report and you receive a letter confirming no violations were identified. This is the goal.

Minor violations. The most common outcome. The IOI issues a Report of Violations listing every finding. You will be asked to acknowledge the findings and describe corrective actions. For minor, first-time violations, this is typically the end of it: fix the issues, document your corrections, and move on.

Significant violations. If violations are numerous or serious, the ATF may schedule a warning conference with your local Area Supervisor. This is a formal meeting where the ATF presents the findings and gives you an opportunity to respond. A warning conference is a serious signal.

Revocation proceedings. In the most serious cases, such as willful or repeat violations after prior warnings, the ATF can initiate license revocation proceedings. You have the right to a hearing before an administrative law judge. The progression is typically Report of Violations, then warning conference, then revocation, and most FFLs never go beyond the first stage.

The time to prepare is now, not the morning an IOI walks through your door. Build these practices into your regular operations and an inspection becomes a non-event.

• Keep your 4473 files organized and accessible, whether alphabetically, chronologically, or by transaction number. The IOI should be able to request any form and have it in hand within minutes.
• Keep your A&D book current with no backlog. Every firearm on premises has an acquisition entry, and every firearm that left has a disposition entry.
• Run regular self-audits and reconcile your physical inventory against your records.
• Resolve and document any discrepancies as soon as you find them.
• Train every employee who receives firearms or processes sales, and document the training.
• Retain denied and non-completed forms along with completed ones.

Digital recordkeeping turns the scramble into a search. With e4473, every completed 4473 is encrypted and retrievable in seconds, and a dedicated ATF audit portal lets an inspector review only your compliance records while the rest of your business stays private.
