RampID Mapping Files

Mapping files are flat files that allow you to see a mapping between an external identifier (such as a cookie, mobile device ID, connected TV ID, or custom ID) and a RampID, our pseudonymous, universal identifier. These files are delivered to you on a regular basis.


  • For EU and UK customers, these types of files are referred to as “conversion files”.

  • RampID mapping files are not available in APAC markets.
