The Service Area PUF (SA-PUF) is one of the seven files that make up the Marketplace PUF. The SA-PUF contains issuer-level data on the geographic coverage or service area (i.e., where the plan is offered) including state, county, and zip code. These data either originate from the Service Area template (i.e., template field), an Excel based form used by issuers to describe their plans in the QHP/SADP application process, or were generated by CCIIO for use in data processing (i.e., system-generated).
