Apple customer number
The Apple customer number is the account number (or numbers) assigned to your organization by Apple, used to purchase Apple hardware or software. It’s required in order to verify your organization’s eligibility for certain programs. If you don’t know the number(s), contact your purchasing agent, finance department, or Apple account team. This number isn’t the same as your GSX account number.
Note: When entering your Apple customer number, leave off any leading zeros.
