  content: '# Generating unique_id


    The `unique_id` refers to the **device identifier** and is platform-specific. You can generate the unique ID for Android and iOS using the methods listed below.


    ### 1. Android


    The platform-specific device ID (or Unique ID) can typically be retrieved from the SDK''s core functionality after initialization. [Android Documentation](https://moengage.github.io/android-api-reference/core/com.moengage.core/[android-jvm]-mo-e-core-helper/get-mo-engage-device-id.html)


    ### 2. iOS


    The device ID can be retrieved using the following method:


    ```swift

    MoEngageSDKCore.getMoEngageDeviceId(completionHandler: @escaping UserInfoHandler)

    ```
