Merchant Chain is a six-digit field that must be numeric and can contain all zeros. The member uses this field to identify the chain within the member system. The system validates the merchant chain in the BIN table, along with the hierarchical order of BIN, agent, merchant, and store numbers defined in the BIN key in the BIN profile.
