Background Checks:
FTIP and NICS in Illinois

Every firearm sale processed through a federally licensed firearms dealer (FFL) in Illinois must pass through the state's own background check system before the transfer can be completed. The Illinois State Police Firearms Transfer Inquiry Program, commonly known as FTIP, serves as the state-level point-of-contact system that works alongside the federal National Instant Criminal Background Check System (NICS).^[3]

How FTIP Works

When a buyer selects a firearm at a licensed dealer, the dealer contacts the ISP Firearms Services Bureau to initiate a FTIP background check. Unlike states that rely solely on the FBI's NICS system, Illinois operates as a "point-of-contact" state, meaning the ISP conducts its own search and also queries the FBI's NICS database as part of a single, consolidated check.^[1]

Databases Searched

During a FTIP inquiry, the ISP searches multiple state and federal databases, including:

• The FBI's National Instant Criminal Background Check System (NICS)
• Illinois criminal history records maintained by the ISP
• Department of Human Services records relating to mental health adjudications and involuntary commitments
• Department of Human Services records relating to developmental disability determinations
• Active orders of protection and firearms restraining orders

The Illinois Department of Human Services maintains files on individuals who have been involuntarily committed or adjudicated as mentally defective, and the ISP accesses these records directly during the FTIP check.^[3]

FOID Card as a Prerequisite

Unless an exception applies, the buyer must display a currently valid FOID card or a currently valid Illinois concealed carry license. The FOID card itself requires a background check at the time of issuance and renewal, meaning that a buyer who passes FTIP has effectively cleared two layers of screening, one at the time of FOID issuance and a second at the point of sale.^[2]

Processing and Outcomes

A FTIP inquiry returns one of three results: approved, denied, or delayed. An approval allows the dealer to proceed with the transfer once any applicable 72-hour waiting period has elapsed and all other legal requirements are met. A denial means the buyer is prohibited from completing the purchase. A delay means the transfer may not proceed while the records found need further analysis. If the ISP cannot resolve the inquiry, the transfer remains on hold. Illinois is a point-of-contact state, and under 430 ILCS 65/3.1 the dealer must receive an explicit ISP approval number before releasing the firearm, no matter how long the delay lasts. The federal NICS three-business-day default-proceed rule does not operate in Illinois.^[3]

Why Illinois Uses Its Own System

The ISP checks state-specific disqualifying conditions, including a conviction within the last five years for battery, assault, aggravated assault, or violation of an order of protection in which a firearm was used or possessed, which bars FOID eligibility under 430 ILCS 65/8(k). Illinois law also requires ISP to report persons prohibited under the FOID Act to the NICS Index, Denied Persons Files. Illinois law also requires the ISP to continuously monitor relevant state and federal databases for firearms prohibitors and correlate those records with FOID cardholders, and provides for suspension or revocation when disqualifying events occur.^[3]

Federal Law Update on NFA Interstate Transport (May 2026)

The DOJ and ATF have proposed, but not finalized, relief from the Form 5320.20 requirement. A notice of proposed rulemaking, Interstate Transport and Temporary Export of NFA Firearms, was published on May 8, 2026 (91 FR 25229), with comments due August 6, 2026. Under the proposal, prior ATF approval would no longer be required for temporary interstate transport of certain National Firearms Act firearms lasting 365 days or fewer. Until a final rule takes effect, NFA owners subject to 27 CFR 478.28 must still submit Form 5320.20 and receive approval before transporting covered items across state lines. Section 478.28(c) exempts qualifying licensees.

Illinois generally prohibits possession of machine guns, short-barreled rifles, and short-barreled shotguns under 720 ILCS 5/24-1(a)(7). Section 24-2(c) provides exceptions, including for persons with a Curios and Relics license who possess a rifle with a barrel or barrels less than 16 inches in length and for qualifying military reenactors. Federal NFA registration alone does not create an Illinois exemption. 720 ILCS 5/24-1(a)(6) prohibits possession of any device or attachment designed, used, or intended for silencing the report of any firearm, and a federal NFA tax stamp does not create an exception under Illinois law. Section 24-2(g-5) exempts persons licensed under federal law who are actually engaged in manufacturing suppressors, firearms, or ammunition, for activities within the lawful scope of that business. Section 24-2(g-7) also exempts peace officers serving on tactical response or special operations teams using government-owned suppressors. Suppressors are outside the firearms listed in the federal interstate transport approval requirement.
