Settings. Secure#ANDROID_ID returns the Android ID as an unique for each user 64-bit hex string. It’s known to be null sometimes, it’s documented as “can change upon factory reset”. Use at your own risk, and it can be easily changed on a rooted phone.
What is the difference between device ID and product ID?
The Device ID (Advertising ID) is a distinctive number associated with a device. This number is important for technicians and engineers when trying to find solutions to ongoing issues. And it will change if you reset or install new Windows. The Product ID is the number associated with your particular operating system.

The apps can track you by linking your Advertising ID — a unique but resettable number used to tailor advertising — with other identifiers on your phone that are difficult or impossible to change. Those IDs are the device’s unique signatures: the MAC address, IMEI and Android ID.
How do I find the unique ID of my phone?
If you’re on an Android phone, it’s just as simple:
- Go to Settings > About Phone. Your phone ID (IMEI) should be one of the first things you see.

What are the best practices for unique identifiers?

What are the different types of Android identifiers?
Android identifier scope generally comes in three flavors: 1 Single app: The ID is internal to the app and not accessible to other apps. 2 Group of apps: The ID is accessible to a pre-defined group of related apps. 3 Device: The ID is accessible to all apps installed on the device.
