The Energy Identification Code is the in_Domain / out_Domain value that identifies this zone in a pan-European market query. Verify it against the official EIC registry before relying on it: several countries publish aliased bidding-zone, control-area and market-balance-area domains, and the correct one depends on what is being asked for.
