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 organization may have more than one Apple customer number. If you don’t add these during enrollment, you can add them at any time.
Communicate and enter ID information
If you purchase devices through participating Apple Authorized 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 organization’s Organization ID to the participating Apple Authorized Reseller or carrier, and verify that they received it.
Add the Reseller ID of your participating Apple Authorized Reseller or carrier to your customer numbers list.
Arrange with your participating Apple Authorized Reseller or carrier to have them submit your orders through their portal to Apple (it won’t happen automatically).
Important: If you don’t know the Reseller ID of your participating Apple Authorized Reseller or carrier, contact them for assistance.
Add an Apple customer number or a Reseller ID
In Apple Business Manager , sign in with an account that has the role of Administrator.
Tap Settings at the bottom of the sidebar, then tap Device Management Settings below Organization 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 already be saved.
Note: When entering your Apple customer numbers, leave off any leading zeros.
