Advertising ID

The advertising ID is a unique, user-resettable ID for advertising, provided by Google Play services. It gives users better controls and provides developers with a simple, standard system to continue to monetise their apps. It enables users to reset their identifier or opt out of personalised ads (formerly known as interest-based ads) within Google Play apps.

Implement advertising ID

To implement advertising ID in your apps, you can use the Advertising ID API.

Policy requirements

The Google Play Developer Programme Policy requires that all updates and new apps uploaded to Google Play use the advertising ID (when available on a device) in place of any other device identifiers for any advertising purposes. You're responsible for ensuring that your apps are in compliance with policies regarding usage, as well as all Play policies.

Apps using a persistent ID other than the advertising ID may receive a policy violation warning via the publisher site or the email address used to register the account. If you receive a warning, you should ensure that any published APKs comply with the advertising ID related guidance in the Developer Programme Policy. If you are using a third-party ad SDK, please contact the SDK maker to obtain a new version that complies with this new policy.

Targeting devices without an advertising ID

When an advertising ID isn’t present, your app may fall back to using a persistent or proprietary identifier, as long as you:

Advertising ID violations
