Seller ID

This number identifies a single merchant. A merchant may operate under multiple MCCs so they may be assigned multiple Industry SE numbers under their Seller ID.

• For full service and back end only merchants, the Seller ID is a combination of the four-digit bank number and the back-end merchant ID, and the field is populated automatically.
• For front end only merchants, you need to enter the Seller ID as defined by the Back End Processor.
