Get your Energy Identification Code (EIC)

The EIC codes are used for the official and unambiguous identification of the actors (TSO, Shipper, Trader, Producer, Exchange platform operator, ...) and points (IP, GEL, balancing zone, domestic outlet, ..).

The idea is to harmonize and standardize electronic communication through unique energy identification codes that are used on the ENTSOE and ENTSOG Transparency platforms, in AS2 and AS4 communications, in Edig@s messages, for Remit and PRISMA.

Fluxys is recognized as Local Issuing Office (LIO) and can grant local EIC codes.
