What Happens If You Fail a Background Check?
By AGO
October 26, 2026
A background check returns one of three answers, and only one of them, a denial, has a process you can challenge. Knowing which one you got is the first thing to sort out, and it changes everything you do afterwards.
The word people use for this is failed, which is doing a lot of work it has not earned. Two of the three possible answers are not a finding about you at all, and one of them resolves on a clock without anyone doing anything.
American Gun Owners put this together from the FBI's own published process. If you are earlier in the sequence and want the background check explained from the start, our guide to how background checks work covers that ground.
Key takeaways
-
A check returns one of three answers: proceed, delayed, or denied.
-
The FBI states you may only challenge, or request a reason for, a check that was denied, not one that was delayed.
-
A delayed check runs on a three-business-day federal clock before a dealer may proceed.
-
A denial can be an identity match rather than a finding about you, which is what the Voluntary Appeal File exists to address.
-
Applying to the Voluntary Appeal File requires fingerprints and produces a Unique Personal Identification Number.
The short version
| Find out first whether your check was delayed or denied. A delay runs on a clock and often resolves itself, and a denial is the only one of the three with a process you can act on. |
|---|
What are the three possible outcomes of a check?
Proceed, delayed and denied are the three, and they are governed differently. Nothing called a fail appears anywhere in the system, which is part of why the language around this gets so muddled.
| Outcome | What it means | What happens next | Can it be challenged? |
|---|---|---|---|
| Proceed | The transaction may go ahead | The dealer may transfer the firearm | Not applicable |
| Delayed | More time is needed to look for information | A three-business-day federal clock runs before a dealer may proceed | No. The FBI states you may only challenge a check that was denied |
| Denied | A determination was made on the transaction | The transfer does not go ahead at that time | Yes. You may request the reason and challenge the decision |
The practical value of that table is the right-hand column. A reader who has been delayed and goes looking for an appeal process is looking for something that does not apply to them, and a reader who has been denied and waits for it to clear will be waiting indefinitely. So the first question to ask at the counter is simply which of the three you got.
Delayed, and what the clock actually does
A delayed check runs on a three-business-day federal clock before a dealer may proceed. That is the whole mechanism, and it exists to give the system time to find information rather than to impose a waiting period on you.
Two things about that clock are worth being precise on. It is business days, so a Friday afternoon delay covers more calendar time than it sounds like. And the end of the clock permits a dealer to proceed rather than requiring it, so a dealer who prefers to wait for a definite answer is entitled to. Policies on that vary and it is a fair question to ask before you leave.
Plenty of delays resolve before the clock runs out, with a proceed arriving hours or a day later. Our guide to how long a purchase takes sets the clock in the context of the whole timeline, including state waiting periods, which are a separate thing layered on top.
Worth saying plainly, because it is the question people arrive with: ask which of the three answers you got. A delay and a denial are different things and only one of them has a process. The person at the counter can tell you that much even though they cannot tell you anything else, and it is the single most useful sentence you can say in that moment.
What does a denial actually mean?
A denial is a determination made on that transaction, and it is the only one of the three outcomes with a route to contest it. The transfer does not go ahead at that point.
What a denial does not tell you, by itself, is why. The categories that prevent a purchase are federal and in some cases state-level, and our guide to what disqualifies a purchase sets them out in full. This page stays on what happens next rather than on what might have caused it.
The important thing to hold on to is that a denial is a decision about a transaction based on records, and records can be about somebody else. Identity matches are common enough that the FBI runs a program specifically for people they affect, which is covered below.
How do you find out why?
The dealer cannot tell you, and the FBI operates a defined process for requesting the reason. The person behind the counter genuinely does not have the information, so pressing them achieves nothing except an uncomfortable few minutes.
The FBI's challenges and appeals process covers both requesting the reason for a denial and challenging it. The two are related but separate steps, and the FBI states plainly that both are available only for a check that was denied, not for one that was delayed. Fingerprints are not required to challenge a denial, though the FBI recommends providing them, because they are what resolves an identity question definitively.
We are not going to put a number of days on any of this. Neither of the FBI pages read for this article publishes a timeline, and a figure invented for the sake of completeness would be worse than no figure at all. The process is published, it has defined steps, and how long yours takes is not something we can tell you.
One more thing about the counter itself. The transaction has a number attached to it, and keeping whatever paperwork or reference you are given makes every later step easier, because the process asks you to identify the transaction you are asking about. Take a photograph of anything you are handed before you leave.
The Voluntary Appeal File
The Voluntary Appeal File exists for people who are repeatedly delayed or wrongly denied because their details match somebody else's record. The FBI describes it as a way to combat erroneous denials and extended delays in future checks.
Applying to the Voluntary Appeal File requires fingerprints. Applicants found to have no firearms prohibitions are issued a Unique Personal Identification Number, which they then provide on later background checks. The FBI is clear that this does not replace the check itself: you still undergo a complete background check, and the number helps confirm that you are you.
Anyone may apply, and it is designed for the specific situation of believing you are eligible while experiencing denials or long delays. If that describes what has been happening to you more than once, this is the part of the process worth reading properly.
What if it happens again?
A denial that was overturned once can recur, and the FBI says so directly. Where a record cannot be updated or corrected, or where a denial was overturned because fingerprints clarified identity, a person can be denied again on a biographical match to a prohibiting record.
That is the single most useful thing on this page for anyone in that situation, because it reframes a repeat denial from a mystery into a known pattern with a known remedy. It is also precisely why the Voluntary Appeal File exists rather than being a formality. A successful challenge resolves one transaction; the file is what carries forward.
If this is your situation and the purchase is still something you want to complete, the Find My Gun Kit quiz will show you what is available where you live while the administrative side runs its course.
It is also worth separating this from anything you may have read about state-level processes. Some states run their own point of contact for checks rather than going directly to the federal system, and where that applies the challenge is made with the state agency that issued the determination rather than with the FBI. Which one applies to you depends on where you bought, and the dealer will know which system they queried.
Getting back to the purchase
Most of this resolves administratively, and the useful move is finding out which of the three answers you actually got. Everything else follows from that one fact.
Ask at the counter which outcome came back. If it was a delay, ask the dealer what their policy is at the end of the clock. If it was a denial, go to the FBI's published process rather than to a forum, and consider fingerprints early since they are what settles identity questions. And if none of this is your situation and you are simply reading ahead, our guide to the form itself covers the step before the check. Instruction is worth booking either way, and AGO's training access connects you with instructors near you.
Frequently Asked Questions
Can you appeal a delayed background check?
No. The FBI states you may only challenge, or request a reason for, a check that was denied, not one that was delayed. A delay runs on a three-business-day federal clock and frequently resolves before it expires. If delays keep happening to you across multiple purchases, the Voluntary Appeal File is the route that addresses that pattern.
How long does a NICS challenge take?
We are not going to give you a number, because neither FBI page we read for this article publishes one and inventing a range would be worse than saying so. What is published is the process and its steps. If timing matters to your situation, the FBI's own pages are the place to look and are updated in a way an article is not.
Does a denial mean you have a criminal record?
Not necessarily. A denial is a determination on a transaction based on records, and records can relate to somebody with similar details. The FBI runs the Voluntary Appeal File specifically because biographical matches cause erroneous denials, and it notes that a denial overturned once can recur for the same reason.
Will the dealer tell you why you were denied?
They cannot, and it is not a matter of policy or discretion on their part. The reason is requested from the FBI through its published process rather than at the counter. The dealer can tell you which of the three outcomes came back, which is the piece of information you actually need from them.
Can you just try again at a different store?
It changes nothing. The same system is queried wherever you go, so a second attempt produces the same answer and leaves you no better informed. The route that does something is requesting the reason and, where it applies, using the challenge process.
