Between August and October 2025, Google implemented a system that automatically verifies and links active phone numbers across all accounts signed into an Android device. This process occurs without an explicit user prompt, associating the device number with secondary profiles, work accounts, and other handles.
Why it matters
Google performs this verification to maintain the currency of communication and account recovery features across its ecosystem. The change effectively consolidates identity data across disparate user accounts by default.
Google updated its support documentation to reflect that the system now automatically links device phone numbers across multiple signed-in accounts. The process runs as a background mechanism, with confirmation sent via email from noreply-phone-verification@google.com.
The players
The provider of the Android operating system and a suite of cloud-based identity and communication services.
The details
The system operates as a background verification process on Android devices. It identifies the SIM-associated phone number and propagates it across every logged-in Google account found on the device, including work or secondary profiles. This behavior contrasts with older models that treated identity across accounts as siloed or manually managed.

The Tech Race
This development follows the documented trend of the consolidation of Google Account identity management features. It marks a shift from manual, per-account verification toward a unified device-level identity framework that synchronizes contact data across an entire user profile ecosystem.
Users can stop future linking by disabling the phone number verification toggle in their account settings. To remove existing associations, users must visit the Personal Info page of every individual account linked on their Android device.
The takeaway
The automatic linking of phone numbers across all profiles can inadvertently bridge professional and personal digital footprints. Users should regularly audit their Personal Info pages to ensure they retain control over which accounts share specific recovery and communication data.
