supplier
The supplier is the entity from which you purchased eligible devices. If you purchased the device directly from Apple using a purchase order (PO), then you would enter your Apple Customer Number as your supplier using the Apple (Direct) option. If you purchased your device through a participating Apple Authorised Reseller or mobile provider, then you would add them as a supplier to your account by entering their Reseller Number using the Reseller option. Each supplier needs to be added only once to your account profile.
