Idaho Guide

Last Updated: 04/17/2026

Note: This guide covers statewide requirements. Some counties or cities may have additional procedures or regulations that are not listed here — always check with the local sheriff or police department before applying or purchasing. This information is for general guidance and is not legal advice.

Quick Cheat Sheet

Buying a Gun:

  • Minimum age: 21 Handgun, 18 Long gun (exceptions for private sales see below)
  • Licensing: None.
  • Dealer sales background check: Required.
  • Waiting period: None.
  • Private sales: No background check required.

Concealed Carry:

  • Permit required? No. Idaho has permitless carry for U.S. citizens 18 and older who can legally possess a firearm. Idaho offers two optional licenses, a Concealed Weapons License (CWL) and an Enhanced Concealed Weapons License (ECWL), that provide certain benefits. A provisional CWL is an option for those 18-20 but requires the training of the ECWL, carries no NICS excemption for purchases, and offers severely limited reciprocity. Trans people should carefully weigh these benefits against the risks detailed below before applying.
  • Training required? Not required for permitless carry. Training is up to the issuing Sheriff’s discretion (commonly required) for a Concealed Weapons License (CWL) and required by statute for an Enhanced Concealed Weapons License (ECWL).
  • Out-of-state permit recognition: Yes, Idaho recognizes valid permits from all states.

Trans Safety Note:

Idaho is a constitutional carry state and permits are optional for in-state carry. Arm the Dolls recommends that trans people carefully evaluate whether an optional CWL or ECWL application is necessary for their use case. See Trans-Specific Considerations below.

Special Notes:

  • Idaho has statewide preemption of firearm laws.
  • No red flag laws. State law explicitly preempts any body from issuing or accepting extreme risk protection orders.
  • No assault weapon or magazine capacity restrictions.
  • No firearm registration requirements. Firearm registries are explicitly prohibited by statute.
  • Both CWL and ECWL holders are exempt from the federal NICS background check requirement when purchasing a firearm from an FFL dealer. The Provisional CWL (ages 18–20) does not qualify for this exemption.

How to Buy a Gun in Idaho

Prerequisites

  • Age: 21 Handgun through an FFL, 18 Long gun. Those 18-20 may purchase handguns through private sales.
  • Residency: Federal law requires all handgun purchases to occur in your state of residency. Buyers must be U.S. citizens or legal residents. State residency is not required for long gun purchases from FFL dealers in Idaho.
  • ID requirements: Valid and current government-issued ID required for FFL purchases.
  • Prohibited-person highlights: Felons, domestic violence misdemeanors or restraining orders, unlawful drug users, fugitives, those adjudicated mentally defective or committed, and other federally prohibited categories.

Dealer Purchase Steps

  1. Visit a Federal Firearms License (FFL) dealer.
  2. Present valid ID, proof of residency, and complete the ATF Form 4473.
  3. Dealer conducts a background check through the Tennessee Instant Check System (TICS).
  4. If approved, complete the purchase.

CWL/ECWL Purchase Benefit: If you hold a valid Idaho CWL or ECWL, you are exempt from the NICS background check requirement for all dealer firearm purchases.

Private Sales / Gun Shows

  • No background check is required for private, in-state sales between non-licensed individuals.
  • At gun shows, only sales by non-licensed attendees are treated as private sales; licensed dealers must run a background check.
  • Federal prohibited-person rules still apply at gun shows and for private sales.

Special Categories / Exceptions

  • Long guns vs handguns vs NFA items: No special restrictions for long guns or handguns. NFA items (e.g., suppressors) are legal with the appropriate federal paperwork.
  • Non-resident purchases allowed only for long gun purchases and the purchaser must comply with federal law and the laws of their home state.

Waiting Period & Timing

  • Waiting period (days): Idaho has no waiting period for firearm purchases.
  • Notes / exceptions: Immediate purchase upon background check approval.

Common Pitfalls / Practical Tips

  • While 18-20 year-olds may purchase handguns through private sales, federal law sets the minimum age to buy handgun ammunition from an FFL at 21. Those under 21 who wish to purchase handgun ammo must do so through private sales.
  • Confirm dealer requirements for proof of residency.
  • Ensure all information on the ATF Form 4473 is accurate to avoid delays.
  • If NICS is delayed, dealers may be required to hold the firearm per federal rules.
  • Federal law creates various exceptions for law enforcement and military personnel which are not covered by these guides. Consult your official sources.
  • Marijuana users of any kind are prohibited under federal law from possessing firearms. The ATF and many courts treat a medical marijuana card as presumptive evidence of unlawful use. Marijuana use while possessing a firearm is a felony, though recent court rulings are challenging this, and the Supreme Court has taken up a relevant case with a ruling likely in June or July of 2026.

How to Carry Concealed in Idaho

System Type

  • Permitless (Constitutional) Carry. Legal per Idaho Code § 18-3302 for any U.S. citizen 18 years or older who can legally possess a firearm.
  • Two optional licenses exist in Idaho. A Concealed Weapons License (CWL) is available and provides certain benefits including the NICS purchase exemption and some out-of-state reciprocity. An Enhanced Concealed Weapons License (ECWL) is a more rigorous process that provides broader interstate reciprocity and is the only credential allowing carry on public college and university campuses. Fundamentally, the difference between either license and permitless carry is the ability to carry on public college campuses (ECWL only) and the NICS background check exemption for dealer purchases (both licenses).

Prerequisites

  • Age: 21 for both CWL and ECWL. Those 18–20 may apply for a Provisional CWL, which expires on their 21st birthday, requires ECWL training, provides no meaningful reciprocity, and cannot be used for the NICS purchase exemption. Since permitless carry already covers in-state needs for this age group, the Provisional CWL has limited practical value.
  • Residency: Must be a U.S. citizen or current Armed Forces member. Non-residents may apply for the CWL or ECWL. The 6-month Idaho residency requirement may be satisfied by holding a current valid concealed carry permit from your home state. Once issued, resident and non-resident licenses are identical in form and function.
  • Training: Required for both CWL and ECWL. See Training Requirements below.
  • Disqualifying factors: Felony convictions, certain misdemeanor convictions, adjudicated mental incompetence, dishonorable discharge, and any condition that makes the applicant prohibited under federal law (e.g., involuntary commitment or unlawful controlled substance use). This list is not exhaustive, consult an official resource (relevant statute can be found here).

Application Steps

  1. Complete required training (see Training Requirements below).
  2. Download and complete the CWL application (available from the Idaho Sheriffs’ Association and individual county sheriff websites, found here).
  3. Appear in person at your county sheriff’s office. Applications are not accepted online or by mail for initial applications.
  4. Submit completed application, firearms training documentation, and valid driver’s license or state ID.
  5. Submit fingerprints (taken at the sheriff’s office at time of application).
  6. Pay applicable fees.
  7. Background check is conducted through the Idaho State Police Bureau of Criminal Identification (BCI) with FBI criminal history records check.
  8. Upon approval, you will be notified and must appear in person to be photographed and receive your license.

Training Requirements

  • Concealed Weapons License (CWL): The issuing sheriff may require demonstration of firearms familiarity (Per Idaho Code § 18-3302(9)). While this is discretionary, not mandatory, in practice most counties do require it. Accepted forms are broad and include hunter education, NRA courses, law enforcement training, military service, organized shooting competition, or any other training the sheriff deems appropriate. An online course through the Idaho Sheriffs’ Association is accepted in most counties. Hunter education, NRA courses, law enforcement training, and military service are also accepted. Requirements vary by county. Some sheriffs require in-person training even for the standard CWL. Confirm with your local sheriff before enrolling in a course.
  • Enhanced Concealed Weapons License (ECWL): 8 hours of in-person classroom and live-fire training, completed within 12 months prior to application. Must include Idaho firearms law and use of deadly force, basic concepts of safe and responsible handgun use, self-defense principles, and live fire with at least 98 rounds. The legal instruction component must be provided by a licensed Idaho attorney or an Idaho peace officer with minimum Intermediate POST certification.

Processing Time

  • Typically 30–60 days. Limited by statute to 90 days.

License validity period

  • Both the CWL and ECWL are valid for 5 years from date of issuance.
  • Renewals may be submitted up to 90 days before expiration or within 90 days after expiration at the standard renewal fee (relevant statute found here). Renewals submitted 91–180 days after expiration incur a $10 late penalty. After 180 days, a full new application and initial fees are required.

Restrictions / Prohibited Places

  • Courthouses, juvenile detention facilities, adult correctional facilities, prisons, and jails.
  • Public and private K–12 schools, school transportation, and school-sponsored activities.
  • Public college and university campuses – unless you hold an ECWL. ECWL holders may carry on campus; CWL holders and permitless carriers may not.
  • Dormitories, residence halls, and public entertainment or sporting facilities with seating capacity of 1,000 or more are excluded even for ECWL holders. (Idaho Code § 18-3302K)
  • Secured areas of airports, nuclear facilities, and certain government buildings like post offices where firearms are restricted by federal law.
  • Posted private property. Property owners may require you to leave; refusal to leave constitutes trespassing.
  • Do not carry while intoxicated or under the influence of any drug; carrying while intoxicated is a misdemeanor.

Reciprocity

  • Out-of-state permits recognized: Yes, Idaho recognizes all valid concealed carry permits from all other states.
  • Idaho licenses recognized elsewhere:
    • CWL: Recognized by fewer states.
    • ECWL: Recognized by approximately 38–39 states. Check the Idaho State Police reciprocity page for the current list (found here). California, Oregon, and New York do not recognize any out-of-state permits.

Denial & Appeal Process

  • Idaho’s CWL and ECWL are shall-issue licenses and as such the sheriff must issue to any qualified applicant. There is no administrative appeals agency. If your application is wrongfully denied, per statute (relevant § 18-3302(18) and 18-3302K(10)), the remedy is a civil action in district court to compel issuance. You may file in the county where you applied or in Ada County at your discretion. If you prevail, you are entitled to costs including reasonable attorney’s fees.
  • Revocations of an existing license require a formal hearing under Idaho’s Administrative Procedure Act (Relevant PDF found here Idaho Code Title 67, Chapter 52). Grounds for revocation include fraud or misrepresentation in obtaining the license, misuse of the license, a condition arising after issuance that would have been grounds for denial, violation of the statute, or a subsequent disqualifying conviction. If you are subject to a revocation consult an attorney.

Common Pitfalls / Practical Tips

  • Permitless carry is for those 18+. The CWL and ECWL both require age 21.
  • The ECWL is the only credential that permits carry on public college campuses.
  • Even with permit, private property owners may override carry rights and ask you to leave.
  • Carrying in prohibited places can result in serious penalties.
  • Carrying while intoxicated can result in serious penalties.
  • Ensure your CWL/ECWL is renewed before expiration to avoid legal issues.
  • Federal law creates various exceptions for law enforcement and military personnel which are not covered by these guides. Consult your official sources.

Associated Fees

  • CWL or ECWL (initial): Varies by county, typically between $55 and $65.
  • Concealed Carry Permit Renewal: Varies by county, typically between $38–$43.
  • Late renewal fee (91–180 days after expiration): $10 additional, per statute.
  • Training course costs (ECWL, PCWL): Set by individual instructors and not governed by statute. Expect $50–$150+ depending on instructor and location.

Trans-Specific Considerations

IMPORTANT: Gender marker changes on Idaho birth certificates are NOT possible as of January 8, 2026. A federal court dissolved the longstanding injunction blocking enforcement of Idaho’s birth certificate law (HB 509, enacted 2020, modified 2024). Trans people born in Idaho can no longer obtain a corrected birth certificate.

IMPORTANT: Gender marker changes on Idaho driver’s licenses are effectively banned. In 2024, Idaho enacted HB 421, a broad sex definitions law mandating all state agencies recognize sex as binary and “biological.” Idaho’s Department of Transportation quietly interpreted this law to require an amended birth certificate for any driver’s license gender marker change. This reversed the previous status quo physician’s affidavit process that had been in place since 2013. This change was implemented without public announcement. When the birth certificate injunction fell in January 2026, the driver’s license pathway fell with it. Trans people born in Idaho now have no viable path to updating either document. Trans people born outside Idaho may still be able to update their driver’s license using a corrected out-of-state birth certificate, depending on their state of birth.

IMPORTANT – A Note on Enhanced Permits and Constitutional Carry: While many constitutional carry states offer optional enhanced or extended permits that provide benefits like reciprocity in other states, we generally advise caution before applying for these permits given the current regulatory environment’s hostility to our community.

Evidence from states like Texas shows that trans people who sought information about updating gender markers on firearms documents were tracked in databases for undisclosed purposes, demonstrating that permit applications can be used to create targeted lists of trans gun owners.

In states with hostile administrative regimes, the modest benefits of enhanced permits may not outweigh the privacy and safety risks of voluntarily placing yourself in additional government databases.

Each member of our community must weigh these considerations based on their individual circumstances and needs, but if constitutional carry already allows you to carry without a permit in your home state, further enhanced permits may be unnecessary and carry serious risk.

Name Changes in Progress

  • Driver’s License / ID and Firearm Purchases: Your ID must be current and valid at the time of purchase. If your name change is finalized but your ID has not yet been updated, you may face delays or denial. If possible, complete your ID update before attempting to purchase. Note that if your current license does not reflect your gender identity, your ability to update it depends on where you were born. See the Important notices above.
  • CWL / ECWL Applications: If you submit an application and your legal name changes during processing, notify your issuing authority immediately. Failure to update your information could result in application denial or a permit issued under an incorrect name, which may create legal complications when carrying.
  • Form 4473 Accuracy: The ATF Form 4473 must reflect your current legal name as it appears on your government-issued ID. The form also asks for sex information; at present, using the gender marker on your current government-issued ID is the standard practice. Using identifying information that does not match your ID could constitute providing false information and may result in denial or legal consequences.
  • Practical Implications: Idaho’s current policy environment creates significant practical barriers for trans people seeking accurate identification documents, which in turn complicates firearm purchases and permit applications. Exercise caution and verify your current documentation status before proceeding

Updating an Existing CWL / ECWL Permit After Name Change

  • Where to update: Your issuing county sheriff’s office. Contact the county where your license was originally issued.
  • Required documentation: Your current CWL or ECWL and an updated government-issued driver’s license reflecting your new legal name. This process is not governed by statute but ATD reached out to multiple Idaho counties to confirm the process.
  • Processing fee: Varies by county. $3-10 reported.
  • Processing time: Varies by county.
  • Important note on carrying: Your CWL permit should reflect your current legal name before you carry concealed. A mismatch between your ID and permit could create complications during a law enforcement encounter.

Notes:

  • Requirements and fees may vary between Idaho’s 44 counties. Contact your issuing sheriff’s office directly to confirm exact documentation and fees.
  • There are ongoing regulatory developments regarding sex designation requirements on Form 4473. We are monitoring this situation and will update this guide as more information becomes available.

Idaho-Specific Considerations

  • Local ordinance preemption: Yes. Local governments cannot impose firearm regulations stricter than state law.
  • Assault weapons / magazine limits: No statewide assault weapon ban or magazine cap beyond any established federal restrictions.
  • ERPO / Red flag laws: Not in effect. Idaho has repeatedly rejected ERPO proposals. Domestic violence protective orders may still result in federal firearms prohibitions under 18 U.S.C. § 922(g)(8).
  • Registration requirements: None.
  • Safe storage laws: Not required by state law.
  • Transportation rules: Idaho has one of the most permissive vehicle carry regimes in the country. Any person meeting the age and eligibility requirements may transport any firearm in a vehicle, loaded or unloaded, handgun or long gun, openly or concealed, without a permit, case, or trunk requirement. There is no duty to inform law enforcement that you are carrying. The federal Gun-Free School Zones Act creates a 1,000-foot perimeter around K-12 schools where this does not apply, unless you hold a valid CWL or ECWL.
  • Stand Your Ground / Castle Doctrine: Yes to both. Idaho passed Stand Your Ground in 2018. No duty to retreat anywhere a person has a legal right to be.
  • NFA items: All legal with proper federal compliance.
  • Ghost guns / unserialized firearms: Not prohibited at the state level. Federally, the ATF rule upheld by the Supreme Court in Bondi v. VanDerStok (March 2025) requires commercial sellers of weapons parts kits and unfinished frames or receivers to be federally licensed, serialize their products, and conduct background checks on buyers. Personal home manufacture of a firearm for personal use without selling it remains federally legal. Check current ATF guidance for specifics on what parts and kits are covered under the rule

Frequently Asked Questions (FAQs)

Can non-residents buy a gun in this state?
Non-residents may purchase long guns from Idaho FFL dealers if they comply with federal law and their home state’s laws. Handgun purchases at dealers are generally restricted to state residents under federal law.

Are private sales required to do background checks?
No. Private sales between non-licensed individuals do not require background checks in Idaho. Federal prohibited-person rules still apply.

How long is the waiting period?
There is no waiting period for firearm purchases in Idaho.

What is the minimum age to buy a handgun?
21 from a dealer. Those 18–20 may purchase handguns through private sales. Note that federal law restricts handgun ammunition dealer sales to those 21 and older.

Do I need a permit to carry concealed?
No. Idaho allows any U.S. citizen 18 or older who can legally possess a firearm to carry concealed without a permit. Optional CWL and ECWL licenses are available for reciprocity and campus carry benefits. Arm the Dolls has important guidance regarding additional licenses in Constitutional Carry states (found here).

What is the difference between the CWL and the ECWL?

Both require age 21, cost approximately $61, and are valid for 5 years. Both exempt holders from the NICS background check at dealer purchases. The ECWL requires 8 hours of in-person training including live fire with at least 98 rounds, while the CWL requires only basic firearms familiarity training (an online course qualifies in most counties). The ECWL is recognized by approximately 38–39 states for reciprocity compared to far fewer for the CWL, and is the only credential allowing carry on public college and university campuses in Idaho.

Where am I prohibited from carrying even with a permit?
Courthouses, jails, K–12 schools, federal facilities, and public college campuses (unless you hold an ECWL, with exceptions for dormitories and large entertainment venues). Private property owners may require you to leave.

Are ghost guns or unserialized guns legal?
Idaho does not prohibit unserialized firearms at the state level, but federal rules may apply. Check ATF guidance.

Are out-of-state permits recognized here?
Yes. Idaho recognizes all valid concealed carry permits from all other states.

How long does the permit process typically take?
Typically 30–60 days, with a statutory maximum of 90 days.

What happens if my concealed carry permit is denied?
Idaho’s licenses are shall-issue. If wrongfully denied, you may bring a civil action in district court to compel issuance under Idaho Code § 18-3302(18) and § 18-3302K(10). Consult an Idaho attorney.
