I Was Denied a Firearm—What Happens Now?

Firearm-Related Challenge

If you believe you have been wrongfully denied a firearm, you can request a firearm-related challenge (appeal). You may only challenge a denied firearm transaction, not a delayed one.

This process will provide you:

• the reason your background check was denied, and

• the opportunity to challenge your denied background check online – including a Nuclear Regulatory Commission background check.
  ​

State Permits

The FBI does not accept challenges or provide reasons for delays or denials on state-issued firearms permits. Those questions should be directed to the state agency. The NICS Participation Map explains whether your state, or the FBI, conducts firearms buyers’ background checks.

How to File a Firearm-Related Challenge

To challenge your firearm denial, visit https://www.edo.cjis.gov.
​

To submit a challenge through the mail, send a request to:

FBI CJIS Division
Attn: Criminal History Analysis Team 1
BTC 3
1000 Custer Hollow Road
Clarksburg, WV 26306

When submitting a challenge via mail, include your NICS Transaction Number (NTN) or State Transaction Number (STN). Failure to include these numbers will delay processing.
