As an Intune admin, you can identify devices as corporate-owned to refine management and identification. Intune can perform additional management tasks and collect additional information such as the full phone number and an inventory of apps from corporate-owned devices. You can also set device restrictions to block enrollment by devices that aren't corporate-owned.

At the time of enrollment, Intune automatically assigns corporate-owned status to devices that are:

• Enrolled with a device enrollment manager account (all platforms)
• Enrolled with the Apple Device Enrollment Program, Apple School Manager, or Apple Configurator (iOS only)
• Identified as corporate-owned before enrollment with an international mobile equipment identifier (IMEI) numbers (all platforms with IMEI numbers) or serial number (iOS and Android)
• Joined to Azure Active Directory with work or school credentials. Devices that are Azure Active Directory registered will be marked as personal.
• Set as corporate in the device's properties list

After enrollment, you can change the ownership setting between Personal and Corporate.

Identify corporate-owned devices with IMEI or serial number

As an Intune admin, you can create and import a comma-separated value (.csv) file that lists 14-digit IMEI numbers or serial numbers. Intune uses these identifiers to specify device ownership as corporate during device enrollment. Each IMEI or serial number can have details specified in the list for administrative purposes.

This feature is supported for the following platforms:

Add corporate identifiers by using a .csv file

To create the list, create a two-column, comma-separated value (.csv) list without a header. Add the 14-digit IMEI or serial numbers in the left column, and the details in the right column. Only one type of ID, IMEI or serial number, can be imported in a single .csv file. Details are limited to 128 characters and are for administrative use only. Details aren't displayed on the device. The current limit is 5,000 rows per .csv file.

Upload a .csv file that has serial numbers – Create a two-column, comma-separated value (.csv) list without a header, and limit the list to 5,000 devices or 5 MB per .csv file.

Important

Some Android and iOS/iPadOS devices have multiple IMEI numbers. Intune only reads one IMEI number per enrolled device. If you import an IMEI number but it is not the IMEI inventoried by Intune, the device is classified as a personal device instead of a corporate-owned device. If you import multiple IMEI numbers for a device, uninventoried numbers display Unknown for enrollment status.
Also note:Serial Numbers are the recommended form of identification for iOS/iPadOSOS devices.Android Serial numbers are not guaranteed to be unique or present. Check with your device supplier to understand if serial number is a reliable device ID.Serial numbers reported by the device to Intune might not match the displayed ID in the Android Settings/About menus on the device. Verify the type of serial number reported by the device manufacturer.Attempting to upload a file with serial numbers containing dots (.) will cause the upload to fail. Serial numbers with dots are not supported.
