Android users with more than one Google account on the same phone are finding their phone number attached to accounts they never linked it to. Google Play Services handles this through a feature called Phone number verification, which runs by default and pushes your number to every signed-in account on the device. If you keep a work account, a personal account, and a throwaway account apart on purpose, this setting quietly connects them through one shared detail.
This guide explains what the feature does, how to turn it off, and how to remove your number from accounts that already have it.
What Is Google Phone Number Verification on Android?
The feature confirms your SIM's phone number in the background and attaches it to your Google accounts.
Google Play Services reads the number from the SIM in your phone, verifies it, and then adds it to every Google account signed in on that device. It also covers accounts you add later, so a new account picks up the number the moment you sign in. Google states this behavior in its own support documentation, and the setting arrives switched on, which makes it an opt-out feature rather than an opt-in one.
Most people learn about it only after the fact. Google sends a confirmation email from noreply-phone-verification@google.com once it finishes verifying the number. A Reddit user in r/Android first drew attention to these emails, and reported that Play Services also collects SIM card identifiers and device metadata during the process. Users on GrapheneOS with Play Services installed report the same behavior.
Why Google Adds Your Phone Number to All Signed-In Accounts
Google ties the feature to account security and a few communication tools.
According to Google, a verified number supports:
- Signing in to your account with your phone number and recovering the account
- Emergency location services and finding or securing a lost device
- RCS messaging and video calls, so contacts can reach you by number
- Quick Share between devices
These features work fine for a single main account. The problem starts when you run several accounts on one phone and want them to stay unconnected.
Is Google Phone Number Verification a Privacy Risk?
A shared phone number gives Google a direct link between accounts you chose to keep apart.
Your number does not become public, and Google does not merge the data inside each account. However, the same verified number now sits on all of them, which ties every account back to one real person. If you left your number off a secondary account on purpose, the feature undoes that choice without asking. Anyone who uses separate accounts for privacy, work boundaries, or anonymity loses that separation.
How to Disable Google Phone Number Verification on Android
You disable the feature from the Google section of your phone's Settings app.
Menu names change a little between phone brands, but the path follows the same pattern:
- Open the Settings app on your Android phone.
- Tap Google. Some phones label it Google services or Google services and preferences.
- Tap All services.
- Under Privacy & security, tap Phone number verification.
- Turn off Verify phone numbers automatically.
Several users report that the toggle switches itself back on after some time. Open the same screen again after a few days and confirm it still shows off.
Turning off this switch only stops future linking. It does not remove your number from accounts that Google already updated.
How to Remove Your Phone Number From Your Google Account
You clear existing links from the Personal info page of each Google account.
Use a browser on any device for this part:
- Go to myaccount.google.com.
- Check the profile picture in the top-right corner and make sure you have the right account open.
- Select Personal info.
- Under Contact info, select Phone.
- Open the number you want to remove and check how Google uses it.
- Select the delete icon and follow the prompts.
Switch to your next account from the profile picture menu and repeat the steps. Do this for every account that should not carry your number.
Remove Your Number From 2-Step Verification and Recovery Phone
Deleting the number from Personal info does not always remove it from security features.
Google stores the number separately for 2-Step Verification and the recovery phone, and some services such as Google Pay keep their own copy. On each account you clean up:
- Look at the Usage section on the Phone page to see which services still list the number.
- Open Security (or Security & sign-in) and review the recovery phone and 2-Step Verification options.
- Check the phone settings inside any other Google service you use with that account.
Before you remove a number from 2-Step Verification or recovery, add another working sign-in method, such as an authenticator app, a passkey, or a recovery email. Without one, you risk locking yourself out of the account.
Has Google Changed Phone Number Verification?
Google has not announced any change to how the feature works.
The company has not publicly addressed the reports, and nothing suggests it plans to make Phone number verification opt-in. Until that changes, the manual steps above remain the only way to keep your accounts separate.
Frequently Asked Questions
How do I know if Google linked my phone number to my accounts?
Search your inbox for emails from noreply-phone-verification@google.com. You can also open the Phone section under Personal info in each Google account and see whether your number appears there.
Does turning off Phone number verification remove my number from my accounts?
No. The toggle only stops Google from adding your number again. You must delete the number from each account's Personal info page yourself.
Will removing my phone number break RCS messaging or Find My Device?
Features that depend on a verified number, such as reaching you by number over RCS or signing in with your phone number, may stop working on that account. Keep the number on your main account if you rely on those features.
Why did Phone number verification turn back on by itself?
Some users report that the setting re-enables after a while, possibly after a Play Services update. Check the toggle again periodically to make sure it stays off.
Does this affect phones without Google Play Services?
The linking runs through Google Play Services, so phones without it are not affected. Custom ROMs like GrapheneOS can still see this behavior if you install Play Services on them.
