# Google Is Auto-Linking Phone Numbers to Every Signed-In Account on Android *Published:* 2026-10-18 *Author:* Farzan Hussain ![](https://bestforandroid.com/wp-content/uploads/2026/10/Android-phone-screen-showing-Google-search_featured.jpg) Google may have attached your phone number to accounts you deliberately kept anonymous, without asking. That’s hard to shrug off, especially when the only warning is an email from a no-reply address. Google is automatically verifying phone numbers on Android and linking them to every Google account signed in on the device, including work, secondary, and alternate profiles. The setting, called phone number verification, is on by default, and some users have received emails from noreply Google mail confirming their number was verified. What Google says phone number verification is for ------------------------------------------------- Google’s [support documentation says](https://support.google.com/android/answer/7521240) Android periodically re-verifies your number so features like account recovery, RCS messaging, emergency features, and Quick Share keep working. [Android Authority reports](https://www.androidauthority.com/google-auto-phone-number-verification-android-3723117/) that the page was updated sometime between August and October 2025 to describe the default-on behavior and the linking across every signed-in account. I can see the value of this for a primary account. However, linking the same number to a throwaway or a dedicated work profile is a different thing completely. Why users with separate accounts are upset ------------------------------------------ The change was spotted by a [Reddit user named Nanosinx](https://www.reddit.com/r/Android/comments/1x5isox/google_is_now_selfverifying_phone_number_without/), who noticed Google Play Services verifying and linking numbers on its own. Other users then reported the same verification emails, and many called it a scummy move. The old behavior was opt-in, which is why this lands so badly. Some users also say GrapheneOS shows the same behavior, though possibly only when Google Play Services is installed. Google hasn’t said why it changed the default or whether it plans to reverse it. How to disable phone number verification on Android --------------------------------------------------- Menu names vary slightly by device, but the path is close to this on most phones: 1. Open the Settings app on your phone. 2. Tap Google (or Google services and preferences). 3. Open the All services tab. 4. Under Privacy & Security, tap Phone number verification. 5. Turn off Verify phone numbers automatically. Turning the toggle off only stops future linking. To remove numbers already attached, go to the Personal info page of your Google Account, open Contact info, tap Phone, and delete the number from each account where it doesn’t belong. Though some users report the toggle switching itself back on. Could the one-time storage limit per phone number explain this? --------------------------------------------------------------- This part is my speculation, not something Google has confirmed. Back in May 2026, Google introduced a [one-time limit per number](https://9to5google.com/2026/05/14/google-account-free-storage-changes-15gb/), where the extra 10 GB of promotional storage can only be unlocked once per phone number. If you use a number already tied to another verified account, the new account gets the storage, and the older one loses it. Reports at the time also said new accounts may get only 5 GB unless a number is linked. Now add this recent silent linking of your number to every signed-in Google account. Someone who keeps several accounts on one phone could watch free storage shrink without touching a thing. Anyone running low would face an only choice, which is to buy a Google One subscription. I can’t prove that’s the motive, and Google points to recovery and messaging reasons. But a default that nobody asked for, paired with a storage rule built around phone numbers, is a combination I’m not willing to wave off. Until Google explains itself, checking this toggle takes thirty seconds, and I’d do it today.
