Add corporate identifiers to Intune (2024)

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 by using Google Zero Touch.
• Enrolled by using Knox Mobile Enrollment.
• Enrolled with the Apple Device Enrollment Program, Apple School Manager, or Apple Configurator (iOS/iPadOS only).
• Identified as corporate-owned before enrollment with an international mobile equipment identifier (IMEI) numbers (all platforms with IMEI numbers) or serial number (iOS/iPadOS and Android).
• Enrolled as Android Enterprise corporate-owned devices with work profile
• Enrolled as Android Enterprise fully managed devices.
• Enrolled as Android Enterprise dedicated devices.
• Enrolled as Android Open Source Project (AOSP) corporate-owned user-associated devices
• Enrolled as Android Open Source Project (AOSP) corporate-owned userless devices
• Joined to Microsoft Entra with work or school credentials. Devices that are Microsoft Entra 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:

Learn how to find your Android device serial number.

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.

This .csv file when viewed in a text editor appears as:

01234567890123,device details02234567890123,device details

Upload a .csv list of corporate identifiers

Select the identifiers that you want to overwrite into Intune and choose Ok to add the identifiers. Intune only compares the first duplicate of each identifier.

Imported devices are not necessarily enrolled. Devices can have a state of either Enrolled or Not contacted. Not contacted means that the device has never communicated in with the Intune service.

Change device ownership

Devices properties display Ownership for each device record in Intune. As an admin, you can specify devices as personal or corporate.

1. Go to Devices > All devices.

2. Select a device.

3. Choose Properties.

4. For Device ownership, select Personal or Corporate.

   

When a device's ownership type is changed from corporate to personal, Intune deletes all app information previously collected from that device within seven days. If applicable, Intune will also delete the phone number on record. Intune will still collect an inventory of apps installed by the IT admin on the device and will still collect a partial phone number for the device after it is marked as personal.

When an iOS/iPad or Android device's ownership type is changed from Personal to Corporate, a push notification is sent through the Company Portal app to inform the devices user of this change.To configure push notifications, go to Tenant administration > Customization. For more information, see Company Portal - Configuration.
