Flat File Directory


The Flat File Directory (FFD) served as Oregon's address book for Direct secure messaging addresses from 2014 to August 2021. The purpose of the FFD was to enable participants to find or "discover" Direct addresses for providers outside their own organizations.

In 2020, the Interoperability and Patient Access final rule from CMS established a requirement for providers to list and update their digital contact information in the National Plan and Provider Enumeration System (NPPES). This includes providing digital contact information including Direct addresses and/or FHIR API endpoints. With the new requirement to submit digital endpoints at the national level, the FFD was no longer needed.
