Your Android Phone Adds Your Number to Every Google Account on It. Here's How to Stop It

Keep a separate Google account for work, a side business, or a throwaway email? If it's signed in on your Android phone, it very likely has your phone number attached to it now, whether you added it or not.

That's because Android turns on a setting called Phone number verification by default. When you set up the phone, Google checks your number and adds it to every Google account signed in on that device. That covers accounts added later, too, and any new number you put in the phone.

What happened: The behavior has been in place since around September 2025. Many people are only now noticing it, after getting unexpected emails from Google telling them their phone number was verified.

What this means for you: If you deliberately keep a work, business or personal account separate from your phone number, that separation may already be gone. You can switch the setting off in a minute, but numbers that were already added have to be removed by hand.

What happened

Phone number verification is on by default. Verified numbers are added to all Google accounts signed in on the device, and that applies to both current and future accounts and numbers. Add a new Google account to the phone and it gets linked to every number on the device. Put in a new SIM and that number is added to every account.

The help page was changed sometime between August and October 2025 to describe verification as on by default, and a Google Play services update in September 2025 lists number verification as running automatically during setup. So this isn't brand new. What's new is that people are finding out.

Over the past couple of weeks, Android owners have reported getting emails from noreply-phone-verification@google.com saying a number had been verified, without having done anything. That set off a fresh round of attention this month, and the story picked up again on Saturday, October 24.

Why Google does this

A verified number helps these features work:

What Google doesn't explain is why the number has to go on every signed-in account rather than just one.

The details that matter

• It reaches every account on the phone. That includes work and secondary accounts, as long as they're signed in on the device.
• It keeps re-checking. Google and your carrier periodically re-verify the numbers to make sure they're still yours, and carrier charges may apply.
• It turns on another setting. When phone number verification is on, a setting called Better sharing on Google turns on for one of your accounts. It's used for video calls, messages and notifications through Google services for photos and other content sent to your number.
• It can only be managed on the phone. You can't switch phone number verification off from a computer.
• Turning it off doesn't undo it. Switching the setting off stops future linking. Numbers already attached to your accounts stay there until you remove them.

What about ads? A separate Google account setting, Better ads & Google services, lets a phone number be used across Google services to show you more relevant ads. Any verified number on an Android device can be added to any Google account signed in on it. It isn't confirmed whether numbers added automatically fall under that ads setting, since Google hasn't said publicly, so it's worth checking it yourself (steps below). (If you're reviewing your Google privacy settings anyway, our explainer on Google's privacy policy change for Gmail, Photos and ads covers a related setting.)

Our read: For most people with one Google account, this changes very little. It matters most if you keep accounts apart on purpose, such as a small-business account you don't want tied to your personal number, or an account a family member signs into on your phone.

What to do now

1. Turn off automatic verification on your phone

Menu names can vary a little by phone maker, so look for the closest match.

1. Open your phone's Settings app.
2. Tap Google (on some phones it's called Google services and preferences).
3. Tap All services.
4. Under Privacy & security, tap Phone number verification.
5. Turn off automatic verification.

Before you do, know what you might give up. The features in the table above depend on a verified number, so turning it off may affect phone number sign-in, finding a lost phone, RCS messaging or emergency location features. If those matter to you, you may prefer to leave the setting on and just clean up the accounts that shouldn't have your number (step 2).

2. Remove your number from accounts where it doesn't belong

Do this for each account you want to keep separate:

1. Go to that Google account (on a computer, myaccount.google.com, or on the phone, Settings > Google > Manage your Google Account).
2. Open Personal info.
3. Under Contact info, select Phone and then your number.
4. Choose Delete and then Remove number, and follow the prompts.

Don't remove your recovery phone from your main account. That number is how you get back in if you're locked out. It may take a week before a newly added number can be used to verify it's you for sensitive actions like changing your password, so think twice before removing and re-adding it.

3. Check the ads setting on accounts that keep your number

1. In your Google account, go to Personal info > Phone and select your number.
2. Under Preferences, turn Better ads and Google services on or off.
3. If you see Across Google next to Usage on the Phone page, that number can be used across Google services.

4. Check Better sharing on Google

On the phone, open Settings > Google, select your account at the top, tap Manage your Google Account > Personal info, then under Contact info tap Phone, select your number, and turn Better sharing on Google on or off.

5. Got a "phone number verified" email?

The reported emails come from noreply-phone-verification@google.com. Whatever you receive, the safest move is to skip any links in the message and check your settings directly on your phone and in your Google account, using the steps above.

We'll update this if Google comments on the change.
