Google Links Your Phone Number to All Android Accounts: How to Stop It
Simran Mishra
Google automatically links your phone number to every Google Account signed in on your Android device through Phone Number Verification.
Google Play Services verifies your SIM-based phone number in the background during device setup or later updates.
The feature links your number to personal, secondary, and work Google Accounts signed in on the same smartphone.
Adding a new Google Account or changing your SIM can automatically link the available phone numbers to all signed-in accounts.
Google says phone number verification supports account recovery, lost device tracking, emergency services, RCS messaging, and Quick Share.
Automatic linking may create privacy concerns for users who want to keep their personal, work, and secondary Google Accounts separate.
Open Settings > Google > All services > Privacy & security > Phone number verification to check the automatic verification setting.
Turn off Verify phone numbers automatically to stop future phone number linking across Google Accounts.
Already-linked numbers require manual removal. Visit myaccount.google.com > Personal info > Phone and delete unwanted numbers from individual accounts. Keep another recovery option active.
