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).[1]
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.[2] This dual-layer approach allows the ISP to search databases that the FBI does not have direct access to, creating a more thorough screening process.
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
This multi-database approach is particularly significant for mental health records. 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] Many states do not report mental health records to the federal NICS database with the same level of detail, giving Illinois's system a broader reach in identifying disqualifying conditions.
FOID Card as a Prerequisite
Before a FTIP check can even be initiated, the buyer must present a valid Firearm Owners Identification (FOID) card. 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.[4] This dual-check structure is unique to Illinois among states that use a licensing system and reflects the legislature's intent to create redundant safeguards against prohibited persons acquiring firearms.
Processing and Outcomes
A FTIP inquiry returns one of three results: approved, denied, or delayed. An approval means the dealer may proceed with the transfer (subject to the mandatory 72-hour waiting period). A denial means the buyer is prohibited from completing the purchase. A delay means the ISP requires additional time to resolve an issue in the buyer's records, such as an arrest without a disposition or a name match that requires further investigation. If the ISP cannot resolve the inquiry within three business days, federal law permits the dealer to proceed with the transfer at the dealer's discretion, though many Illinois dealers choose to wait for a definitive response.[5]
Why Illinois Uses Its Own System
Illinois chose to operate a point-of-contact system rather than relying solely on the FBI because it allows the state to maintain greater control over the quality and completeness of records searched. The ISP can include state-specific disqualifying conditions -- such as a conviction for assault or battery within the last five years, which bars FOID eligibility under 430 ILCS 65 -- that the federal NICS system does not track. This state-operated model also gives Illinois the ability to conduct ongoing monitoring of FOID cardholders between purchases, revoking cards when disqualifying events occur.[6]
Federal Law Update: NFA Interstate Transport (April 2026)
The ATF reform package signed on April 29, 2026 eliminated the requirement for prior ATF approval (Form 5320.20) for temporary interstate transport of National Firearms Act items lasting less than 365 days. Previously, NFA owners traveling across state lines with a registered NFA item for a short-term purpose needed to submit Form 5320.20 and receive ATF approval before traveling. Under the new rule, that advance approval is no longer required for temporary transport. Permanent transfer of an NFA item to another state still requires Form 5320.20 approval.
For most Illinois residents, this rule change has limited practical impact. Illinois law bans civilian possession of machine guns, short-barreled rifles, and short-barreled shotguns regardless of federal NFA registration status, so those items cannot be lawfully transported by a civilian in any case. The rule change is most relevant for NFA items that are legal under Illinois law, such as suppressors, which are not banned by state statute and may be possessed with a valid NFA tax stamp. Illinois residents who hold suppressors registered under the NFA may now travel temporarily to other states without obtaining advance ATF approval, provided the destination state permits such items.
