Reseller Number

A Reseller Number is a unique identifier for each Apple Authorized Reseller or authorized cellular carrier who participates in Apple School Manager. When you add a participating Apple Authorised Reseller’s or network provider’s Reseller Number to your account profile (and you give that reseller your Organisation ID), you authorise that reseller to submit devices you purchased through them to Apple so their serial numbers appear in Apple School Manager.

If you do not know the Reseller Number of your participating Apple Authorised Reseller or your authorised mobile network provider, contact them for assistance.
