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 Enterprise Human Resources Integration (EHRI), 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 under the INFORMATION FOR AGENCIES section. The LPA definitions can be found in OPM's Guide to Personnel Data Standards at http://www.opm.gov/PolicyOversight/DataAnalysis/EnterpriseIntegrations/index.aspx#url=Data-Reporting. The ability to search the duty station file on the Internet is also available at this address.
