Understanding common ATF violations helps you avoid them. Based on ATF inspection data and enforcement actions, these are the mistakes that get FFL dealers in trouble—and how to prevent them.
Top 10 ATF Violations
1. Failure to Verify Purchaser Eligibility
What it means: Not properly confirming the buyer can legally purchase a firearm.
Common failures:
- Incomplete Form 4473
- Not verifying ID against 4473 information
- Accepting expired identification
- Not conducting NICS check
- Proceeding during NICS delay without resolution
Prevention:
- Use a 4473 completion checklist
- Train all staff on ID verification
- Never skip NICS—even for "trusted" customers
- Document delay resolution before transfer
2. Inability to Account for Firearms
What it means: Physical inventory doesn't match A&D records.
Common causes:
- Firearms missing with no documentation
- Unreported theft or loss
- Recording errors (wrong serial numbers)
- Dispositions not logged
- Consignment tracking failures
Prevention:
- Conduct monthly inventory counts
- Verify serial numbers at acquisition
- Log dispositions same-day
- Report theft/loss within 48 hours
- Track consignment firearms separately
3. Improper Record Keeping
What it means: A&D records are incomplete, inaccurate, or illegible.
Common failures:
- Missing acquisition information
- Incomplete disposition entries
- Illegible handwriting
- Using white-out (prohibited)
- Gaps in record sequence
Prevention:
- Use standardized logging procedures
- Write legibly or use electronic systems
- Make corrections with single strike-through + initials + date
- Complete entries same-day
- Regular record review
4. Failure to Ensure Traceability
What it means: ATF cannot trace a firearm through your records.
Common causes:
- Serial number transcription errors
- Missing manufacturer information
- Incomplete buyer identification
- Lost or damaged records
Prevention:
- Double-check serial numbers
- Use manufacturer markings exactly
- Complete all 4473 identification fields
- Maintain backup records
5. Improper Transfer Documentation
What it means: Form 4473 errors that make transfers questionable.
Common errors:
- Missing signatures (buyer or seller)
- Unsigned certifications
- Wrong dates
- Incorrect firearm descriptions
- Missing supplemental government ID info
Prevention:
- Review every 4473 before customer leaves
- Use completion checklist
- Verify firearm description matches actual gun
- Ensure all required fields completed
6. Failure to Report Multiple Sales
What it means: Not filing Form 3310.4 for multiple handgun purchases.
Requirement: When same buyer purchases two or more handguns within 5 consecutive business days, file Form 3310.4 no later than close of business on the day of the sale.
Prevention:
- Track customer purchases across 5-day windows
- File Form 3310.4 immediately when triggered
- Send copies to CLEO and ATF
- Retain your copy
7. Failure to Report Theft/Loss
What it means: Not reporting missing firearms within required timeframe.
Requirement: Report theft or loss of firearms within 48 hours of discovery to ATF and local law enforcement.
Prevention:
- Conduct regular inventory counts
- Report immediately upon discovery
- Document when loss was discovered
- Keep copies of all reports
8. Transferring to Prohibited Persons
What it means: Selling to someone who cannot legally possess firearms.
How it happens:
- Ignoring NICS deny result
- Transferring during unresolved delay
- Missing straw purchase indicators
- Not recognizing prohibited person signs
Prevention:
- Never transfer on NICS deny
- Wait for delay resolution (or 3 business days)
- Train staff on straw purchase indicators
- Trust your instincts—refuse suspicious sales
9. Operating Outside Licensed Premises
What it means: Conducting FFL business at unauthorized locations.
Common situations:
- Gun show activities beyond regulations
- Unlicensed storage locations
- Transfers at buyer's location
- Operating from unlisted address
Prevention:
- Understand gun show rules for your state
- Conduct business at licensed premises
- If expanding, get separate FFL for new location
10. NICS Documentation Failures
What it means: Not properly documenting background check process.
Common failures:
- Missing NTN (NICS Transaction Number)
- No documentation of proceed/delay/deny
- Transferring before NICS response
- No record of delay resolution
Prevention:
- Record NTN on every 4473
- Document NICS response (proceed/delay/deny)
- Track delay cases separately
- Never transfer without proper NICS completion
Violation Severity Levels
Minor Violations
Typically result in Report of Violations with opportunity to correct:
- Isolated record-keeping errors
- Minor 4473 omissions
- Clerical mistakes
Significant Violations
May result in Warning Letter or Warning Conference:
- Pattern of record-keeping failures
- Repeated 4473 errors
- Late multiple sale reports
- Inventory discrepancies
Severe Violations
Can lead to revocation proceedings:
- Willful violations
- Transfer to prohibited person
- Falsifying records
- Repeated violations after warnings
- Refusing to allow inspection
What "Willful" Means
ATF focuses on "willful" violations for serious enforcement. Willful means:
- Intentional disregard of known requirements
- Plain indifference to compliance
- Repeated violations after being informed
- Not the same as intentional criminal conduct
Honest mistakes, while still violations, are treated differently than willful non-compliance.

Frequently Asked Questions
Can I lose my FFL for one mistake?
A single isolated mistake rarely results in revocation. However, severe violations (like transferring to prohibited persons) or willful violations can escalate quickly. Patterns of violations are most concerning.
How do I correct a 4473 error?
Draw a single line through the error, write the correction, initial, and date. Never use white-out. If discovered after customer leaves, you may need to have them return to initial corrections.
What if ATF finds violations I didn't know about?
Ignorance isn't a defense, but unintentional violations are treated differently than willful ones. Cooperate, correct the issues, and demonstrate your commitment to compliance.
