By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27. - ID: MOB-41 - Level: Required - Chapter: [Signing and release](https://agentwranglers.se/playbook/mobile-apps/signing-and-release.md) - Rule: Verify your identity with Google and register every Android package name with its signing key, including apps sold outside Google Play. Finish before the date it applies in your users' countries. - Check: Before each release, the console lists every package name the team ships, each as registered with the signing key of the release build. The check fails on any package missing from the list. - Risk: The app down or unusable - Region: Brazil (BR), Indonesia (ID), Singapore (SG), Thailand (TH). The duty comes from the law there. The rule applies only when the project serves people there, and its Applies when also holds. - Review by: 2027-03-31 - How: Since 30 September 2026, certified devices in Brazil, Indonesia, Singapore and Thailand refuse apps from unregistered developers in participating stores. There, an unregistered app cannot be installed at all, so new users never get it. Google plans to extend verification to all apps on certified devices worldwide in 2027. Google Play registers most apps signed with Play App Signing on its own. Apps sold only outside Google Play register in the Android Developer Console, and an organisation needs a D-U-N-S Number. A lost signing key blocks registration, which is one more reason to [let the store hold the signing key and back up the upload key](https://agentwranglers.se/playbook/mobile-apps/signing-and-release/signing-keys.md). Installs over ADB need no registration, so test builds keep working. For a small test group, a limited distribution account covers up to 20 devices at no cost. ## Sources - [Android developer verification](https://developer.android.com/developer-verification) - [Android developer verification FAQ](https://developer.android.com/developer-verification/guides/faq) ## Related rules - MOB-49 [Weigh alternative app marketplaces and web distribution](https://agentwranglers.se/playbook/mobile-apps/store-review-and-listing/alternative-distribution.md) in Mobile apps - MOB-7 [Let the store hold the signing key and back up the upload key](https://agentwranglers.se/playbook/mobile-apps/signing-and-release/signing-keys.md) in Mobile apps **For agents:** this playbook is free to use under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/), which requires credit with a link.
