ATF Form 4473: The Buyer Questions, Denials, and Waiting Periods

ATF Form 4473, officially the Firearms Transaction Record, is the federal document you fill out any time a licensed dealer transfers a firearm to you. It captures your identifying information, asks a set of yes-or-no eligibility questions drawn from federal prohibited-persons law, and gives the dealer what they need to run your background check through the FBI’s National Instant Criminal Background Check System. The form is required for every retail sale by a Federal Firearms Licensee. It is not required by federal law for private sales between two unlicensed people, though many states impose their own rules on those transfers.

What You Fill Out at the Counter

You complete the buyer’s section of Form 4473 in person at the dealer’s place of business. You provide your full legal name, date of birth, place of birth, and current residence address. A P.O. Box will not work; ATF needs a physical address that can be tied to the firearm if a trace request is ever made.¹ Height, weight, sex, and race are also required and help distinguish you from other people who share your name.

Your Social Security number is optional, but including it is one of the best ways to keep your check from getting delayed or wrongly denied. Common names generate false hits constantly, and the SSN narrows the search.¹

You need a valid government-issued photo ID, usually a driver’s license or state ID card. The dealer confirms that the name, date of birth, and photo match what you wrote. If the address on your ID is not your current address, bring a supplemental government document that shows where you actually live. A vehicle registration or tax document works.¹

Non-citizens have extra steps. If you are a nonimmigrant alien, the form asks for your immigration status and requires your U.S.-issued alien or admission number.² Federal law generally prohibits nonimmigrant visa holders from possessing firearms, though a narrow set of exceptions applies to people holding valid hunting licenses and a few other categories.³

The Eligibility Questions

The core of Form 4473 is a series of yes-or-no questions that track the federal prohibited categories in 18 U.S.C. § 922(g). Lying on any of them is a federal crime punishable by up to five years in prison and a fine up to $250,000.⁴ You are prohibited from buying if you fall into any of these groups:

Anyone convicted of, or under indictment for, a crime punishable by more than one year in prison.
Fugitives from justice.
Unlawful users of controlled substances, which includes marijuana no matter what your state law says.
Anyone a court has found to be a danger due to mental illness, or who has been involuntarily committed.
Anyone dishonorably discharged from the military.
Anyone subject to a qualifying domestic violence protective order, or convicted of a misdemeanor crime of domestic violence.
Anyone who has renounced U.S. citizenship or is in the country unlawfully.

Marijuana and Other Controlled Substances

The drug question trips up more buyers than any other. Federal law still treats marijuana as a controlled substance, so regular users are prohibited under 922(g)(3) even in states where it is legal. A 2026 ATF rulemaking narrowed the definition of “unlawful user” to someone who uses a controlled substance “with sufficient regularity and recency to indicate that the individual is actively engaged in such conduct,” meaning isolated or sporadic past use no longer automatically disqualifies you.⁶ Current, regular marijuana use still makes you a prohibited person under federal law.

Domestic Violence Convictions

A misdemeanor conviction does not need to be labeled “domestic violence” to trigger the federal bar. What matters is whether the offense involved the use or attempted use of physical force, or the threatened use of a deadly weapon, against a spouse, former spouse, co-parent, cohabitant, or dating partner. Convictions involving dating partners became qualifying offenses on June 25, 2022, under the Bipartisan Safer Communities Act.⁷

Exceptions exist. The prohibition does not apply if you were not represented by counsel and did not knowingly waive that right, or if you were entitled to a jury trial that never happened and did not waive it. A pardon, expungement, or restoration of civil rights removes the prohibition unless the action itself expressly bars you from possessing firearms.⁷

The Actual Buyer Question

The first question on Form 4473 asks whether you are the actual buyer of the firearm. You are the actual buyer if you are purchasing for yourself or acquiring the gun as a genuine gift. You are not the actual buyer if someone else gave you money or anything of value to buy the firearm for them, or if the person you plan to give it to is a prohibited person.¹

Lying here is treated far more harshly than a general false statement. Straw purchasing is a standalone federal crime under 18 U.S.C. § 932, carrying up to 15 years in prison and a $250,000 fine. If the straw-purchased firearm is used in a felony, an act of terrorism, or a drug trafficking crime, the ceiling rises to 25 years.⁸ A related statute, 18 U.S.C. § 933, adds up to 15 years for knowingly trafficking a firearm to a prohibited person or someone who will use it in a felony.⁹

What Happens After You Hand It Back

Once your section is done, the dealer submits your information to NICS by phone or through the FBI’s electronic portal. In 31 states, five U.S. territories, and the District of Columbia, the FBI runs the check directly; in the rest, a state agency handles it and queries NICS on the FBI’s behalf.¹⁰ The system searches three databases and returns one of three answers:

Proceed. No disqualifying record was found and the dealer can complete the transfer.
Denied. A matching prohibited record was found and the sale stops.
Delayed. The system needs more time to resolve a possible match.

¹⁰

The Three-Business-Day Rule

If NICS delays a check for a buyer 21 or older, the FBI has three business days to resolve it. If no final denial comes in that window, the dealer may legally transfer the firearm at their discretion under 18 U.S.C. § 922(t).³ Many dealers still choose to wait for a definitive answer. Whichever way the check clears, the transfer must happen within 30 days of the NICS contact; after that the dealer must run a fresh check.¹¹

Under-21 Buyers

The Bipartisan Safer Communities Act built a longer process for buyers between 18 and 20. When NICS runs a check on someone under 21, it also contacts state juvenile justice agencies, mental health record custodians, and local law enforcement to look for disqualifying juvenile records that standard federal databases would not show.¹² The normal three-day window runs first. If the system finds cause to dig further, that window extends to 10 business days.³ A buyer under 21 could wait up to two full weeks for a delayed check to clear.

If You Get Denied

False denials are common, usually because your name matches someone else’s criminal record or a database has outdated information. If NICS denies your purchase, you can appeal. Start by requesting the reason for the denial in writing from the FBI, by mail or through their online portal. The FBI must provide the general reason within five business days of receiving your request.¹³

Your appeal can include court documents, proof that a record was expunged, or evidence that the disqualifying record belongs to someone else. If the problem is mistaken identity, submitting fingerprints lets NICS confirm you are not the person in the criminal record. Appeals go through either the state point-of-contact agency that ran the check or the FBI’s NICS Section. A successful appeal produces documentation you can bring back to the dealer.¹³

If you have already been delayed or denied more than once, apply for the FBI’s Voluntary Appeal File. Once approved, you get a Unique Personal Identification Number, or UPIN, that you enter on every future Form 4473. NICS then uses your cleared file to confirm your identity quickly and avoid the same false match. Anyone eligible to own a firearm can apply. The application requires a completed VAF form and a fingerprint card, and the FBI processes requests within 60 calendar days. You can file a VAF application at the same time you appeal a denial.¹⁴

If You Have a Past Prohibition

Falling into a prohibited category is not always permanent. Under 18 U.S.C. § 925(c), a prohibited person can apply to the Attorney General for relief from firearms disabilities by showing that their record and reputation indicate they are unlikely to endanger public safety and that restoring their rights would not be contrary to the public interest. A denial can be appealed to a federal district court.¹⁵ For a domestic violence misdemeanor, a pardon, expungement, or full restoration of civil rights removes the firearms bar unless the order itself says otherwise.⁷

State restoration processes vary widely. If you think an old conviction no longer bars you, get a definitive legal answer before you walk into a dealer. A wrong guess produces both a denied sale and a potential false-statement charge.
