Contains the Service Establishment number and will contain either the Specific SE number assigned to the merchant (i.e. Discover SE, AMEX SE) or the HIMMS2-merchant number if the transaction is being processed on the international platform. This number is assigned to a merchant by Elavon and identifies the merchants profile and the settlement currency requirements. It should be noted that for each settlement currency required there will be a unique SE number assigned. This format does not support AMEX transactions from T&E merchants, for example airlines, hotels, and car rentals.
