Ammunition Background Check Requirement

New York requires ammunition sellers to conduct a background check before transferring ammunition to any purchaser under Penal Law Section 400.03. This article explains the seller registration process, the background check procedure, the in-person transfer requirement, and the penalties for noncompliance.

Overview

New York Penal Law Section 400.03 generally requires a firearms dealer or registered ammunition seller to complete a database background check before a commercial transfer of ammunition to an individual purchaser.^[1] The statute contains limited exceptions when the system is not operational, cannot be accessed because of a temporary technological or electrical failure, or the Superintendent of State Police has granted a waiver. In October 2025, the Second Circuit affirmed the denial of a preliminary injunction against enforcement of the requirement. That decision concerned preliminary relief rather than a final merits judgment.^[2]

Seller Registration

A seller of ammunition must register with the Superintendent of State Police before conducting sales. A firearms dealer validly licensed under Penal Law Section 400.00 does not complete the separate seller registration.^[1]

Background Check Process

Before transferring ammunition to a person who is not a firearms dealer or ammunition seller, the dealer or seller generally must complete the following steps:

• Verify identity: For a New York resident, the transferor examines a valid state identification document issued by the Department of Motor Vehicles. For a nonresident, the transferor examines a valid identification document issued by the person's state or country of residence that contains a photograph.^[1]
• Contact the database: The dealer or seller provides the statewide license and record database with the information required to identify the parties and ammunition.^[1]
• Obtain a unique ID: If the database determines that the purchaser is eligible, it assigns a unique identification number to the transfer.^[1]

The dealer or seller generally may not complete the transfer until the database provides the required result and unique identification number. The statute does not apply this requirement during a qualifying system outage or temporary access failure, or when the Superintendent has granted a qualifying waiver.^[1]

Eligibility Determination

The database determines whether the available information demonstrates that receipt of ammunition would violate 18 U.S.C. Section 922(g) or state law.^[1]

In-Person Transfer Requirement

A commercial transfer of ammunition must use a licensed firearms dealer or registered ammunition seller as the intermediary, and the final transfer from that dealer or seller to the recipient must occur in person.^[1]

Record-Keeping Requirements

Sellers and firearms dealers must record every ammunition transaction in a format approved by the Superintendent of State Police. Each entry must include the date, the name, age, occupation, and residence of the person from whom ammunition is received or to whom it is delivered, and the amount, caliber, manufacturer's name, and serial number or, if none, another distinguishing number or identification mark on the ammunition.^[1]

When a checked transaction is completed, the database creates a transaction record accessible by the State Police and maintained for no longer than one year. The statute says that record is not incorporated into the statewide license database or pistol and revolver registry.^[1]

Constitutional Challenge and Court Ruling

In New York State Firearms Association v. James, the plaintiffs sought a preliminary injunction against enforcement of the ammunition background-check requirement. On October 15, 2025, the Second Circuit affirmed the district court's denial of that preliminary injunction. The ruling left the requirement enforceable while the litigation proceeded, but it was not a final judgment resolving every merits issue.^[2]

Practical Considerations

For an ordinary online retail purchase by an individual, the ammunition must be sent to a New York licensed firearms dealer or registered ammunition seller. That intermediary completes the required check and transfers the ammunition in person. Governmental and organizational keepers of ammunition and transactions in which no ownership transfer occurs may be governed by different rules.^[3]

Penalties

Penalties for violating PL 400.03 vary by offense:

• Unregistered seller who sells ammunition, first offense: Violation and a $1,000 fine.^[1]
• Unregistered seller who sells ammunition, second offense: Class A misdemeanor.^[1]
• Failure to keep a required record, first offense: Violation and a $500 fine.^[1]
• Failure to keep a required record, second offense: Class B misdemeanor, and the seller's registration is revoked.^[1]
