Unique Serial Number Application

Commencing July 1, 2018, any person who possesses a self-manufactured or self-assembled firearm that does not bear a serial number assigned to it shall apply to the Department of Justice (Department) for a unique serial number by January 1, 2019.

Additionally, commencing July 1, 2018, prior to manufacturing or assembling a firearm, a person shall apply to the Department for a unique serial number.

We recommend that you review California Penal Code sections 29180-29184 and the California Code of Regulations, title 11, division 5, chapter 41 for complete instructions on the process and information regarding firearms that are eligible for a unique serial number prior to starting the application process.

Required Applications

Please note that two applications (available July 1, 2018) will be submitted during the USNA process; one to complete your firearms eligibility check and the other to request for serial number assignment. The following applications shall be submitted concurrently as noted below:

  1. Request for Unique Serial Number – Personal Firearms Eligibility Check (PFEC) Application (BOF 120) via U.S. mail for the firearms eligibility check. Download the PFEC Application at https://oag.ca.gov/firearms/forms.
  2. USNA via the California Firearms Application Reporting System (CFARS) for request of unique serial numbers. Access CFARS at https://cfars.doj.ca.gov.
    • Prior to submitting the USNA through CFARS, you will submit the requisite associated fee(s).

Fees Associated With Obtaining a Unique Serial Number

The initial fee for submitting an application for a unique serial number is $35.00. This fee will cover the $20.00 cost for the firearms eligibility check conducted by the Department (BOF 120) and the request for one unique serial number for one firearm through CFARS. If you have multiple self-manufactured or self-assembled firearms or if you intend to manufacture or assemble multiple firearms, you may request multiple unique serial numbers during the same transaction. The fee for each subsequent unique serial number within the same transaction is $15.00. There is no limit to the number of unique serial numbers that an applicant may request within a single application and corresponding transaction.

What to expect after submission of the applications

Once both completed applications are submitted and received, the Department will notify you via the CFARS and/or U.S. mail whether you are eligible or ineligible to receive a unique serial number. If you are approved, you must engrave the assigned serial number on the firearm within the associated timeframe (manufactured/assembled or intend to) and are required to upload images through CFARS.
