Firearm registration systems are a useful method of curbing illegal gun activity and encouraging responsible gun practices. 

Laws requiring gun owners to register their firearms ensure gun owner accountability and help law enforcement solve crimes and disarm criminals. Despite the clear advantages inherent in registration laws, few states have such laws on the books—and some prohibit them outright.


Firearm registration laws require individuals to record their ownership of a firearm with a designated law enforcement agency. These laws enable law enforcement to identify, disarm, and prosecute violent criminals and people illegally in possession of firearms. Registration systems also create accountability for firearm owners and discourage illegal sales. Information generated by firearm registration systems can also help protect law enforcement officers responding to an incident by providing them with information about whether firearms may be present at the scene and, if so, how many and what types.

Crime Gun Tracing

Firearm registration laws can lead to the identification and prosecution of violent criminals by helping law enforcement quickly and reliably “trace” (identify the source of) firearms recovered from crime scenes. Firearm registration laws create comprehensive records of firearm ownership, which include a full description of each firearm and identify the owner. Comprehensive registration laws also require a firearm to be re-registered whenever title to the firearm is transferred, and law enforcement to be notified whenever the weapon is lost or stolen. As a result, registration laws help law enforcement quickly and reliably identify the owner of any firearm used in a crime.

Additional information on crime gun tracing, firearm sales reporting requirements and retention of firearm sales records is contained in our summary on Maintaining Records of Gun Sales.

Disarming Ineligible People

Firearm registration laws also help law enforcement retrieve firearms from persons who have become legally prohibited from possessing them through criminal convictions or other prohibitions. Comprehensive registration laws require gun owners to renew their registration annually or explain why they should no longer be legally responsible for the weapon. During the renewal process, owners undergo additional background checks to ensure that they have not fallen into a class prohibited from possessing firearms. The renewal process, therefore, creates an opportunity for law enforcement to remove illegally possessed firearms.

Gun Owner Accountability

In addition, registration laws help reduce illegal firearm sales and transfers by creating accountability for gun owners. A firearm owner who knows that law enforcement has the ability to trace the firearm back to him or her may be deterred from transferring the firearm to a potentially dangerous individual, and may be encouraged to store his or her firearm safely so as to prevent unauthorized access or theft. Registration laws also help deter “straw purchases,” in which an eligible person purchases a firearm on behalf of an ineligible person or a person who wants to avoid having the gun traced back to him or her. For more information about straw purchases, see our summary on Gun Trafficking & Straw Purchasing.

Combining Registration with Licensing

Registration laws are most effective when combined with laws requiring licensing of firearm owners and purchasers.1 A 2001 study analyzing the firearm tracing data of crime guns recovered in 25 US cities revealed that states with some form of both registration and licensing have greater success keeping firearms initially sold by dealers in the state from being recovered in crimes than states without such systems in place.2 This data suggests that licensing and registration laws make it more difficult for criminals, juveniles, and other prohibited purchasers to obtain guns, and help ensure that firearm owners remain eligible to possess their weapons. For more information on licensing laws, see our summary on Licensing.


We’re in this together. To build a safer America—one where children and parents in every neighborhood can learn, play, work, and worship without fear of gun violence—we need you standing beside us in this fight.

Public Support

The American public strongly supports laws requiring gun registration. A nationwide survey conducted in August 2019 found that 62% of respondents favor laws requiring every gun owner to register each gun he or she owns as part of a national gun registry.3 A poll conducted in May 2001 found that 70% of respondents mistakenly believe that a registration system already exists in the United States.4

Summary of Federal Law

There is no comprehensive national system of gun registration. In fact, federal law prohibits the use of the National Instant Criminal Background Check System (NICS) to create any system of registration of firearms or firearm owners.5

A limited system of federal firearms registration was created by the National Firearms Act, 26 U.S.C. § 5801 et seq. The National Firearms Act (NFA) was enacted in 1934 to impose an excise tax and registration requirements on a narrow category of firearms, including machine guns, short-barreled shotguns or rifles, and silencers, and these weapons must also be registered under the NFA.6

In 1986, Congress banned the transfer and possession of machine guns not already in lawful circulation.7 Machine guns that were lawfully owned prior to the ban’s effective date may continue to be owned and transferred provided they are registered in accordance with requirements of the National Firearms Act.8 It is also unlawful for a licensed dealer to sell a short-barreled rifle or shotgun to any person, except as specifically authorized by the Attorney General consistent with public safety and necessity.9

With its provisions effectively limited to pre-ban machine guns and transfers of short-barreled rifles and shotguns that are specifically authorized by the attorney general, the registration system created by the National Firearms Act falls far short of a comprehensive registration system.

For information about the federal law relating to firearms tracing, see our summary on Gun Trafficking & Straw Purchasing.

Summary of State Law

Six states and the District of Columbia have laws that in practice facilitate or require official records and registers of some or all firearms. Hawaii and the District of Columbia require the registration of all firearms, California maintains a database of gun transfer records, and New York requires the registration of all handguns through its licensing law.10 In late 2022, Oregon voters also enacted a ballot measure that will (similar to California’s law) direct the State Police to establish and maintain a state database of firearm purchase permits and gun sale or transfer records for law enforcement purposes.11

Hawaii, New York, and four other states also have a registration system for certain highly dangerous firearms, such as assault weapons. These states generally ban such firearms, but allow for continued possession of registered legacy weapons if they were owned before the ban was adopted and were lawfully registered, recorded, or certified with state or local law enforcement. For more information about such laws, see our summaries on Assault Weapons50-Caliber Weapons, and Large Capacity Magazines.

Additional states require the reporting of firearm sales and transfers to a state or local agency, which maintains these records. For information about such laws, see our summary on Maintaining Records of Gun Sales. California and Maryland also require new residents to report certain firearms that they bring into the state.

Conversely, eight states have statutes prohibiting them from maintaining a registry of firearms except in limited circumstances.

States that Require or Facilitate Registration Records for All Firearms

  • California*
  • District of Columbia12
  • Hawaii13
  • Oregon*

*While California and Oregon do not have a traditional gun registration system (except for assault weapons in California), they generally require all gun transfers to be processed through a licensed dealer and require a state law enforcement agency to maintain records of these transfers in a central database. This system functions similarly to an automatic firearm records registration system.


Hawaii requires registration of all firearms with the county police chief within five days of acquisition. The registration must include: (1) the name of the manufacturer and importer; (2) the model, type of action, caliber or gauge, and serial number of the firearm; and (3) the source from which the firearm was obtained, including the name and address of the previous registrant. In addition, every person who brings a firearm into Hawaii must register the firearm within three days of the arrival of either the person or the firearm, whichever arrives later.14 Hawaii does not require renewal of the registration. Hawaii also has a licensing scheme, requiring that all firearm purchasers obtain a permit prior to acquisition.15

The District of Columbia

The District of Columbia’s registration law limits the availability of many classes of firearms within the District. While the District requires a valid registration certificate for every gun that is purchased, sold, transferred, or possessed in the District,16 many classes of especially dangerous firearms may not be registered. For example, sawed-off shotguns, machine guns, short-barreled rifles, assault weapons, .50 BMG rifles, and “unsafe firearms” as defined by District law, may not be registered.

The District of Columbia requires that an application for registration be made prior to taking possession of a firearm from a licensed dealer or any person or organization holding a registration certificate for the firearm. In addition to providing detailed identifying information about the registration applicant and the firearm, applicants are also required to provide detailed information concerning: 1) whether the applicant has ever been denied any firearm-related license, permit or registration certificate and, if so, the reasons for such denial; 2) the applicant’s role in any mishap involving a firearm, including the date, place, time, circumstances, and names of the persons injured or killed; 3) if the applicant has applied for other registration certificates; and 4) where the firearm generally will be kept. Applicants undergo a background check conducted by the Chief of Police.

Registration applicants are required to complete a firearm safety course. Registered owners are required to notify the Chief of Police of the loss, theft, or destruction of the registration certificate or of a registered firearm. Registrants must also notify the Chief of the sale, transfer, or other disposition of the firearm within two business days of such sale, transfer or disposition, and must return the registration certificate for any firearm that has been lost, stolen, destroyed, or otherwise disposed of or transferred.17


A 2022 Oregon ballot measure established a permit to purchase process and requires local law enforcement agencies to provide to the State Police a copy of any permit to purchase firearms they issue, and any information necessary for the State Police to maintain an electronic searchable database of such permits.18 The Department of State Police is required to maintain this electronic database by ensuring that new permits are added to the database, renewed permits are assigned a new expiration date, and expired or revoked permits are marked expired or revoked but retained in the database.19 Oregon’s 2022 ballot measure now also authorizes the State Police to retain information provided to a licensed dealer in a firearms transaction sufficient to identify each firearm purchased by a permit holder for inclusion in an electronic law enforcement database.20 The law requires that this information be attached to the electronic record of the permit maintained by the Department of State Police.21

States that Require Registration of Handguns

  • New York22

New York generally requires anyone wishing to possess a handgun to first obtain a license, following a background check. The license must specify the weapon by caliber, make, model, manufacturer’s name, and serial number, and must indicate if the handgun may be carried on the person or possessed in a particular location. A license holder may apply at any time to his or her licensing officer for amendment of the license to include more weapons or to cancel weapons held under license. As of January 15, 2013, such license must be “recertified” with the division of state police every five years. The recertification form requests the license holder’s name, date of birth, gender, race, residential address, social security number, all firearms possessed by such license holder, email address (at the option of the license holder), and an affirmation that such license holder is not prohibited from possessing firearms. A failure to re-certify results in the revocation of the license.

  • New Jersey (new residents only)

As of February 1, 2023, people who become residents of and transport a personal handgun into New Jersey must register them.23 A person who registers a handgun must complete a registration statement that includes the name and address of the person and the make, model, and serial number of the handgun being registered. The registration statement must be submitted to the law enforcement agency of the municipality in which the person resides or, if the municipality does not have a municipal law enforcement agency, any State Police station.24

Registration is not required for existing residents who possess or purchase handguns.

States that Require New Residents to Report Their Firearms

  • California25
  • Maryland26 (handguns and assault weapons)

California and Maryland require new residents to provide a report regarding firearms they own to law enforcement. More specifically, any handgun owner who moves into California from out-of-state on or after January 1, 1998, or any firearm owner who moves into California on or after January 1, 2014, is deemed a “personal firearm importer.” Within 60 days, the person must sell or transfer the firearm through a licensed dealer or to a sheriff or police department, or provide a report to DOJ regarding the firearm. Maryland enacted a similar law in 2013 that requires any new resident to register all handguns or assault weapons within 90 days of moving into the state.

States that Require Registration of Pre-Ban Assault Weapons, 50 Caliber Rifles, or Large Capacity Magazines

  • California27 (assault weapons and 50 caliber rifles)
  • Connecticut28 (assault weapons and large capacity magazines)
  • Hawaii29 (assault pistols)
  • Maryland30 (assault pistols)
  • New Jersey31 (assault weapons)
  • New York32 (assault weapons)

Six states (California, Connecticut, Hawaii, Maryland, New Jersey, and New York) have generally banned assault weapons,33 but allow for continued possession of such weapons if they were lawfully owned on a specified date and are registered, except that legacy assault long guns in Maryland do not need to be registered. In California (the only state that currently bans the possession of 50 caliber rifles) any person who lawfully possessed a 50 caliber rifle before January 1, 2005, must have registered it no later than April 30, 2006, in order to retain possession of the firearm.34

In 2013, Connecticut enacted legislation which bans large capacity ammunition magazines (capable of holding more than 10 rounds), and requires persons lawfully possessing such magazines prior to January 1, 2014 to apply with the state before January 1, 2014 in order to maintain possession. A person moving into the state with a large capacity magazine must apply to maintain possession within 90 days.

States that Require Reporting of Gun Sales or Transfers

Many states require the reporting of firearm sales and transfers to a state or local agency, which maintains these records. For information about such laws, see our summary on Maintaining Records of Gun Sales.

Key Legislative Elements

The features listed below are intended to provide a framework from which policy options may be considered.45 A jurisdiction considering new legislation should consult with counsel.

  • Registration is required for all firearms prior to taking possession, or, in the case of firearms already owned or brought into the jurisdiction, immediately after the firearm is brought into the jurisdiction or the effective date of the law 
  • Registration includes: name, address and other identifying information about the owner of the firearm; names of manufacturer and importer; model, type of action, caliber or gauge, and serial number of firearm; and name and address of source from which firearm was obtained 
  • Registered owners are required to renew registration annually, including submitting to a background check 
  • Registered owners are required to report any loss, theft or transfer of the registered firearm to law enforcement within a short time of the event and to turn in their registration card or certificate upon loss, theft or transfer
  • Registered owners are required to store all firearms safely and securely.
  • Additional restrictions may include limitations on where registered firearms may be possessed and to whom they may be transferred (particularly relevant for certain classes of firearms such as assault weapons, 50 caliber rifles, and large capacity magazines).
