Selling your firearm checklist
This is a practical checklist for a compliant transfer. If anything feels unclear or high-risk, using a licensed dealer is the simplest way to ensure the transfer is correctly documented and legally compliant.
-
1
Confirm the buyer has a valid FOID card.
In Illinois, buyers generally must have a valid Firearm Owner’s Identification (FOID) card to receive a firearm. Do not proceed unless the buyer’s FOID is valid and matches their identity.
-
2
Run the required transfer background check through the state process.
Illinois requires a background check for firearm transfers. Complete the transfer inquiry through the Illinois State Police process and keep the approval record for your files.
-
3
Observe the waiting period before completing the transfer.
Do not deliver the firearm until the 72-hour waiting period has passed and you have confirmation that the transfer is approved. If anything is unclear, stop and use an FFL.
-
4
Document the transfer details for your records.
Keep a clear record of the buyer, the firearm (make, model, serial), the date, and the background check approval information. This protects you if questions come up later.

Consider selling directly to a licensed buyer.
Selling to a federally licensed buyer like WeBuyGuns.com simplifies the process by handling compliance, shipping, and documentation without the uncertainty of private meetups.

State laws for selling a gun in Illinois
Illinois allows private firearm sales, but only when specific state requirements are met. Sellers must verify buyer eligibility, complete a state background check, and observe the required waiting period before transferring a firearm.
If you are selling a firearm in Illinois, you are responsible for confirming FOID status and maintaining proper transfer records. Use the official state resources below to confirm how the law applies to your situation.
| Topic | Status | Notes |
|---|---|---|
| Background check for private transfers | YES | Since Jan 1 2024, private sellers either get an Illinois State Police approval number through the online transfer portal (FOID check) or complete the sale through an FFL (430 ILCS 65/3). |
| FOID verification | REQUIRED | The seller must verify that the buyer holds a valid Firearm Owner’s Identification (FOID) card before completing the transfer. |
| Waiting period | YES | 72-hour waiting period for all firearms (720 ILCS 5/24-3(A)(g)). |
| Assault weapons (PICA) | Registration and sale limits | Illinois's assault weapons and magazine law (PICA, effective Jan 10 2023) remains in force. The Illinois Supreme Court rejected the state-constitution challenge (Caulkins v. Pritzker, Aug 11 2023; U.S. cert denied Jan 8 2024). The 7th Circuit upheld PICA on Jul 9 2026 (Barnett v. Raoul); a petition to the U.S. Supreme Court is due by Nov 6 2026. Separately, the U.S. Supreme Court will hear Viramontes v. Cook County (Cook County's own ban) with Grant v. Higgins on Dec 2 2026. That ruling will likely decide PICA's federal fate. |
| Can I sell to an out-of-state buyer | NO (directly) | Private interstate firearm transfers are prohibited. Out-of-state transfers must go through licensed dealers. |
| Minimum age | YES | Age requirements depend on firearm type and transfer method. Dealers enforce federal age rules and state eligibility requirements. |
| Recordkeeping | REQUIRED | Private sellers must keep transfer records for 10 years (430 ILCS 65/3). |

Avoid FOID issues and transfer delays
Illinois firearm transfers require FOID verification, background checks and strict documentation. Private sales often stall due to eligibility questions or paperwork errors. Selling to a licensed buyer removes FOID uncertainty and ensures full compliance.

Local ordinances, municipal rules and county policies
Illinois firearm transfers are governed primarily by state law, but municipalities and counties retain authority over certain local firearm-related rules. These local regulations do not usually change whether a firearm can be sold, but they can affect how and where a transfer takes place.
- Local dealer zoning and availability: Cities and counties may regulate where licensed firearms dealers can operate through zoning and land-use rules. This can limit which FFLs are available locally if a private transfer must be routed through a dealer.
- Municipal restrictions on possession and transport: Some municipalities impose additional rules related to firearm possession or transport within city limits. These rules do not override state transfer law, but they can affect meeting locations or how a firearm is transported to a dealer.
- Administrative practices by local agencies: Local law enforcement agencies may influence appointment availability, processing times, or documentation expectations when dealers are involved in transfers.
Local ordinances in Illinois rarely change the legal requirements for selling a firearm, but they can slow or complicate the process. Using a licensed buyer with established dealer relationships can help avoid delays caused by local zoning, scheduling, or administrative hurdles.
