Submit your station’s data
with CDP’s step-by-step guides


In order to bring together data from hundreds of different stations with disparate databases, CDP has created a “universal” system that maps individual station source codes and categories into one common CDP Categorization System.

The guide below offers a comprehensive breakdown of each source category code. It also features things to remember when coding, as well as FAQs and tabs that show biographic and transactional field layouts for you to reference when formatting your data.

CDP Source Category Codes for All Database Documents

Stations are responsible for submitting a Donor File and a Transaction File for inclusion in the NRF. We have developed training resources to help with the coding process and file layouts for the most widely used database systems in Public Media
