The Central Reference File Database (CRD) (formerly known as Central Repository Domain) is a centralised database that stores Location Codes and Company Codes.

Common Interface

The CI is an easy-to-install application that can be set up in the user’s premises.


To ensure high security standards along with message-based encryption and signing within this network, RNE acts as a central Certification Authority (CA).
