Apple Business Manager (ABM) uses a device’s serial number to identify devices purchased from Apple or an authorized reseller for enrollment in Automated Device Enrollment (ADE). Serial numbers are unique to each device and linked to purchase records, allowing ABM to verify eligibility. Order numbers (option A) track purchases but aren’t device-specific identifiers in ABM. UDID (option C) and UUID (option D) are unique identifiers for devices or instances, but they’re not used for purchase verification in ABM.
