The Office of Personnel Management (OPM) is responsible for the Duty Station File, while the General Services Administration (GSA) is responsible for maintenance of the code set and issuance of city codes. To ensure completeness of the OPM Duty Station File, which is used to verify the validity of duty stations reported to the Central Personnel Data File (CPDF), requests for codes for personnel use should be directed to OPM at email address CPDF@opm.gov for processing by GSA
In addition to duty station names and codes, the duty station file includes the core based (i.e., metropolitan/micropolitan) statistical area (CBSA), combined statistical area (CSA), and locality pay area (LPA) of each duty station. The CBSA and CSA definitions are available at http://www.whitehouse.gov/omb by selecting Bulletins. The LPA definitions can be found in OPM's Guide to Personnel Data Standards at http://www.opm.gov/feddata/guidance.asp. The ability to search the duty station file on the Internet is also available at this address.
Note that the foreign country, U.S. possession, and U.S. administered area names and codes are in compliance with Federal Information Processing Standards Publication 10-4 (Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions). The U.S. state names and codes are in compliance with Federal Information Processing Standards Publication 5-2 (Codes for the Identification of the States, the District of Columbia and Outlying Areas of the United States, and Associated Areas). The U.S. county names and codes are in compliance with Federal Information Processing Standards Publication 6-4 (Counties and Equivalent Entities of the United States, Its Possessions, and Associated Areas). These standards are published by the National Institute of Standards and Technology, Department of Commerce, and are available at http://www.itl.nist.gov/fipspubs/by-num.htm.
