Google Play Services is verifying the phone number on Android devices and attaching it to every Google account signed in on the same phone, according to a user report posted on Reddit. The user says the verification happens automatically, without a warning or a consent prompt.

The behavior matters most for people who keep separate Google accounts on one device. A common setup includes a personal account, a work account, and sometimes an anonymous account that is meant to stay unconnected to the owner's identity.

Once the same phone number is attached to all of them, that shared number creates a link showing the accounts belong to one person. The link does not make data from one account visible inside another.

The concern is the association itself, which the account owner did not explicitly approve. The Reddit user also says the same thing happened on a device running GrapheneOS, which shows the linking is tied to Google Play Services rather than to the stock software of one phone maker.

Google has not publicly explained why Play Services verifies and links numbers this way, and it has not said when the behavior started.
