Manage device suppliers in Apple Business Manager
You can add your Apple customer numbers and Reseller IDs by adding supplier information as necessary. For example, a large organisation may have more than one Apple customer number. If you do not add these during enrolment, you can add them at any time afterwards.
Communicate and enter ID information
If you purchase devices through participating Apple Authorised Resellers or carriers, you must complete all three steps below, so orders placed with that reseller or carrier appear in Apple Business Manager:
Communicate your organisation’s Organisation ID to the participating Apple Authorised Reseller or carrier and verify that they received it.
Add the Reseller ID of your participating Apple Authorised Reseller or carrier to your supplier list.
Arrange with your participating Apple Authorised Reseller or carrier to have them submit your orders through their portal to Apple (it will not happen automatically).
Important: If you do not know the Reseller ID of your participating Apple Authorised Reseller or carrier, contact them for assistance.
Add an Apple customer number or a Reseller ID
In Apple Business Manager , tap Settings at the bottom of the sidebar, then tap Device Management Settings below Organisation Settings.
Tap Edit next to Customer Numbers, enter your Apple customer numbers or Reseller IDs, then tap Done.
If the Add button is missing or dimmed, this information may have already been saved.
Note: When entering your Apple customer numbers, leave off any leading zeros.
