Trading Partner: Costco
EDI IDs
Costco utilizes the following Electronic Data Interchange (EDI) IDs for identification purposes. These EDI IDs are made up of a Qualifier and an ID which will be sent within their Interchange Control Header, ISA segment, on your inbound transactions. This allows Transaction Manager to be able to identify the Sender and Receiver of any sent/received EDI transaction.
