How to stop Google from linking your phone number to accounts

Android has a setting that quietly attaches your phone number to every Google account signed in on that device, including personal, work, and secondary profiles, without asking first (Android Authority, 9 days ago). If you want to stop Google from linking your phone number to accounts you've deliberately kept separate, you need to do two things: turn off the setting so it stops happening going forward, and manually remove the number from any account where it doesn't belong. This applies if your Android phone has multiple Google accounts signed in and the Phone number verification setting shows up under Google services.

Some people only found out after an unsolicited email from noreply-phone-verification@google.com told them their number had been automatically verified, without them taking any action first (Android Central, 5 days ago). Google's support documentation appears to have been updated sometime between August and October 2025 to reflect this opt-out behavior, and the reporting suggests the change was made with little, or possibly no, notice to users (Android Authority, 9 days ago).

Disabling the toggle only stops new links from forming. It does not remove numbers already attached to accounts, which is why this guide covers both fixes separately: shutting off automatic verification first, then auditing each account's contact info to strip numbers that shouldn't be there (Android Central, 5 days ago).

How to stop Google from linking your phone number to accounts on Android

Start here if you haven't checked this setting before.

1. Open Settings on your phone, then tap Google (some devices label this Google services and preferences) (Android Authority, 9 days ago).
2. Switch to the All services tab, scroll to Privacy & security, and tap Phone number verification (TechRadar, 8 days ago). If you don't see this option, the reporting so far doesn't establish whether that means it's absent from your device, account, or Android version; it just means nobody has confirmed how widely the setting has rolled out.
3. Turn off Verify phone numbers automatically. If this was on, your device has been linking your number across every signed-in account automatically (Android Central, 5 days ago).
4. Back out of the screen, then return a moment later to confirm the toggle held. Reader Bruce Stevens described the setting reverting every single time he came back to the page, and other users report the same thing (Android Authority, 3 days ago). That's based on user reports, not something Google has confirmed as a bug, so check again in a few days instead of trusting one successful toggle.
5. Keep in mind this switch only governs what happens from here forward. Any number already tied to an account before you flipped it stays put until you go remove it by hand, which is the next section.

How to remove a phone number already linked to a Google account

To unlink a phone number from multiple Google accounts, each one has to be checked on its own. The toggle above doesn't reach back and fix accounts that are already linked.

1. Sign into the account you want to check, open Personal info, then go to Contact info (sometimes labeled Personal info) > Phone (Android Central, 5 days ago).
2. If a number shows up that shouldn't be tied to that account, delete it (Android Police, 4 days ago).
3. Before deleting anything, check that account's recovery and security settings so you're not stripping out the only contact method you rely on to get back into it. This matters most on accounts where the phone number is currently the sole recovery option.
4. Repeat this on every Google account signed into the device, personal, work, secondary, and any throwaway profiles, since the fix has to be applied individually to each one (Android Police, 4 days ago).
5. After deleting a number, revisit that account's Personal info > Phone page to confirm it no longer appears.
6. Decide account by account rather than treating removal as the default move. Pull the number from anything you deliberately keep separate, and leave it in place wherever shared recognition across accounts isn't a concern for you.

What Google says versus what's confirmed

Google's documentation, as described by Android Central's reporting, frames periodic phone re-verification as support for account recovery, RCS messaging, emergency features, and Quick Share (Android Central, 5 days ago). Separately, Google's account-verification page says phone checks help confirm a real person is behind an account and help cut down on spam (Google Support, updated last year).

Neither explanation accounts for the scope problem. The process can affect every account signed in on the device, not just the one you're actively using (Android Police, 4 days ago). That creates a shared data point tying accounts together that otherwise had no connection, though the reporting stops short of showing that account content becomes visible across those linked accounts (Android Police, 4 days ago).

Reader sentiment backs up why this bothers people. More than 85% of over 2,000 readers surveyed by Android Authority said the opt-out approach decreased their trust in Google, while roughly 7% saw no change and 3% said their trust actually increased (Android Authority, 3 days ago). Not everyone sees it as a downside: commenter Colin Hines said he manages up to 15 Google accounts for tech-support and volunteer work, and having one number recognized across all of them speeds up sign-in, even while acknowledging the privacy concern (Android Authority, 3 days ago).

A few related reports remain unconfirmed. Google's support page acknowledges a "This phone number has been used too many times for verification" error can appear once a number is tied to enough accounts (Google Support, updated last year). One reader told Android Authority he'd been blocked from creating a new email address for that reason, which is one person's experience rather than proof that automatic cross-account linking caused his specific block (Android Authority, 3 days ago). A Reddit user separately reported the same linking behavior on a GrapheneOS device, possibly tied to whether Google Play Services is installed; treat that as one device-specific report, not a finding about GrapheneOS generally (Android Police, 4 days ago; TechRadar, 8 days ago).

What the reporting does establish: on the devices examined, the setting exists, defaults to on, and links your number across every account signed in there (Android Authority, 9 days ago). What it doesn't establish: why the default is set to on, whether the toggle reverting itself is a bug, or whether that's connected to the verification-limit error some users are hitting. Both Android Central and Android Authority say they contacted Google for comment and hadn't heard back as of publication (Android Central, 5 days ago; Android Authority, 9 days ago).

Check the toggle under Settings > Google > All services > Phone number verification today, then work through the Personal info > Phone page on every account signed into your device. Confirm each account still has a recovery method you control before deleting a number, and look at the toggle again in a few days since some readers have seen it switch back on by itself. Treat the toggle-reversion reports and the GrapheneOS behavior as unresolved until Google responds publicly, and don't assume one clean pass through your accounts means the number is gone for good.
