To get a gun in Illinois, you first need a Firearm Owner’s Identification (FOID) card from the Illinois State Police. Once that card is in hand, you can buy a firearm from a licensed dealer or a private seller, pass a background check, wait out a 72-hour waiting period, and take the gun home. Everything else — concealed carry, what you can own, how you store it — builds on that FOID card.
Who Can Get a FOID Card
You must be at least 21 and an Illinois resident. Applicants between 18 and 20 can apply only with written consent from a parent or legal guardian who holds a valid FOID card themselves and files an affidavit with the Illinois State Police. The consenting parent cannot be someone who would be disqualified from having their own card.1Justia. Illinois Code 430 ILCS 65 – Firearm Owners Identification Card Act
Several things will disqualify you outright:
- Any felony conviction under state or federal law.
- A misdemeanor conviction for a crime of domestic violence, or an active order of protection.
- Involuntary commitment to a mental health facility within the past five years, or adjudication as a person with a mental disability.
- Addiction to narcotics or current unlawful use of controlled substances.
- Fugitive status, renunciation of U.S. citizenship, or a dishonorable military discharge.
These overlap with federal prohibitions, but Illinois adds its own wrinkles. The five-year mental health facility bar is one that catches applicants off guard.1Justia. Illinois Code 430 ILCS 65 – Firearm Owners Identification Card Act
How to Apply
The entire application runs through the Illinois State Police Firearm Services Bureau portal. Have ready a valid Illinois driver’s license or state ID number, a head-and-shoulders digital photograph taken within the last 30 days, and your consent to a mental health records check.2Illinois State Police. Firearm Owner’s Identification (FOID)
The fee is $10, payable by credit card or electronic check, plus a small processing surcharge. You can also submit electronic fingerprints through the Firearm Transfer Inquiry Program. Fingerprints are optional, but submitting them speeds up future firearm purchases and locks in a 10-year card validity period from the date of fingerprint approval.2Illinois State Police. Firearm Owner’s Identification (FOID)
After you submit, the Illinois State Police runs background checks through its own criminal history files, the FBI’s National Instant Criminal Background Check System, and Illinois Department of Human Services mental health records. New applications are processed within 30 calendar days. Allow another 10 days or so for printing and mailing before worrying. Renewals take up to 60 business days.3Illinois State Police.

If the application is denied, the Illinois State Police sends written notice with the reason. You can respond with additional documentation or, for certain denials, appeal to the circuit court in your county of residence.4Illinois State Police. CCL Appeals
Buying From a Dealer
With a valid FOID card, you can walk into any licensed dealer in Illinois and start the purchase. Every dealer sale triggers a background check through the Illinois State Police, which acts as the state’s point of contact for the federal NICS system. A clean check produces an approval number good for 30 days.1Justia. Illinois Code 430 ILCS 65 – Firearm Owners Identification Card Act
Illinois imposes a 72-hour waiting period on every firearm — handgun, rifle, or shotgun. The clock starts when you and the seller agree on the purchase, not when you pay or complete paperwork. The dealer cannot hand over the gun until those 72 hours have passed. Plan accordingly if you are buying on a Friday before a weekend hunting trip.
Buying From a Private Seller
Illinois does not let private sellers skip verification. If you buy from another individual rather than a dealer, the seller is legally required to see your valid FOID card or Concealed Carry License before transferring the firearm. A seller who hands over a gun without checking commits a criminal offense.5Illinois State Police. IL FOID/CCL Card Verification Portal
The Illinois State Police runs an online verification portal where private sellers can confirm a buyer’s FOID card is currently valid. Sellers should use it every time, because a card can be revoked between issuance and the sale date. For gun show sales, the seller must also request that the Illinois State Police run a background check on the buyer and provide the buyer’s FOID card information.5Illinois State Police. IL FOID/CCL Card Verification Portal
Firearms covered by the Protect Illinois Communities Act cannot be transferred through the private sale portal at all. Those transfers must go through a federal firearms licensee who can verify the buyer’s exemption documentation.
Transporting the Gun Home and Beyond
Once you leave the store, the firearm must be unloaded and enclosed in a case, firearm carrying box, or other container. It cannot be immediately accessible. The only exception is for a holder of a valid Concealed Carry License, which allows a loaded concealed handgun on your person. Tossing an uncased rifle in the back seat with a FOID card alone will get you charged, and this is one of the more common mistakes new gun owners make.
Storing a Firearm at Home
Illinois has a child access prevention law that took effect January 1, 2026. If you store a firearm in your home and you know or should know that a minor under 18 without a FOID card could access it, and that minor causes death or serious injury with the firearm, you face criminal charges. The firearm must be either secured with a locking device or kept in a locked container. A first violation is a Class C misdemeanor with a minimum $1,000 fine. A second violation escalates to a Class A misdemeanor.6Illinois General Assembly. Illinois Code 720 ILCS 5/24-9 – Firearms; Child Protection
When You Need a Concealed Carry License
The FOID card lets you own a firearm, keep it at home, and transport it properly cased. It does not let you carry a loaded, concealed handgun on your person in public. For that you need a separate Concealed Carry License, which requires a valid FOID card, 16 hours of state-approved training, a $150 application fee for Illinois residents, and a separate background review by the Concealed Carry Licensing Review Board.7Justia. Illinois Code 430 ILCS 66 – Firearm Concealed Carry Act The CCL has its own disqualifiers on top of the FOID list, including recent violent misdemeanors and two or more DUI arrests in the previous five years. If carrying is part of your plan, start that process separately once your FOID card arrives.
What You Cannot Buy or Own
A FOID card does not open every door. The Protect Illinois Communities Act, effective January 10, 2023, bans the sale, purchase, and manufacture of assault weapons, .50 caliber rifles, and certain accessories in Illinois. As of January 1, 2024, possession of these items is also generally prohibited unless you lawfully owned them before the ban took effect. The law defines a large capacity ammunition feeding device as a magazine that holds more than 10 rounds for long guns or more than 15 rounds for handguns.8Illinois State Police. Assault Weapons
Federal law adds another layer. Short-barreled rifles (barrel under 16 inches), short-barreled shotguns (barrel under 18 inches), suppressors, and machine guns all require registration and a federal tax stamp under the National Firearms Act. Possessing any of these without proper NFA registration is a serious federal felony regardless of what Illinois credentials you hold.9Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts
What Happens If You Skip the FOID Card
Getting caught with a firearm and no FOID card is not a slap on the wrist. The charge ranges from a Class A misdemeanor, carrying up to 364 days in jail, for a first offense, up to a Class 1 felony, carrying 4 to 15 years in prison, for repeat violations or aggravating circumstances. A misdemeanor conviction alone creates a criminal record that makes future firearm ownership harder and can affect employment and housing. The Illinois State Police actively cross-references revoked FOID cards with firearm transfer records, so the assumption that nobody checks is wrong.
