Organization ID
An Organization ID is your unique identifier in Apple Business Essentials. When you give a participating Apple Authorized Reseller or an authorized cellular carrier your Organization ID (and you add that reseller’s Reseller Number to your account profile), you authorize that reseller to submit devices you purchased through them to Apple so their serial numbers appear in Apple Business Essentials. The Organization ID can also be used with app developers so they can distribute Custom Apps specific to your organization.
