Possible problems and solutions
Users may encounter a situation where the system does not accepts a new number. This is often due to the fact that the number was previously used in another account Google too often. The security policy limits the number of associations of one number to different profiles within a short period of time.
Another common problem is a network error when sending the code. In this case, try switching from mobile data to Wi-Fi or vice versa. It is also worth checking whether your smartphone has an ad blocker or VPN, which may interfere with the connection to verification servers.
If you have changed your region of residence, make sure that the country has been changed in your account settings. Some features and number formats may vary depending on your profile's geographic location. A discrepancy between the country code and the actual number may cause a validation error.
In rare cases, a complete update of services is required Google Play. Go to Settings → Applications → Google Play Services and check for updates. An outdated version of system software may not process new security protocols correctly.
Error “This number has been used too often”
This is an anti-spam limitation. You will have to wait a few days or use a different number for verification. As a last resort, contact Google support through the account recovery form.
Frequently asked questions (FAQ)
Can I change my number if I have forgotten my account password?
No, to change the data in your account, you must first log in. If you have forgotten your password, use the access recovery procedure, where the old phone number (if it is still active) or a backup email will help you reset the password.
Will my search history and photos be deleted after changing the number?
Absolutely not. A phone number is just an access and security tool. All your data, including photos in Google Photos, letters in Gmail and search history, are tied to the account itself, and not to a specific phone number.
How many numbers can you add to one Google account?
You can add several numbers, but only one can be the main one for recovery. The rest will be considered reserves. The system does not allow linking the same number to a large number of different accounts at the same time.
What happens if I delete the number and the new one has not yet been confirmed?
This is a dangerous situation. If you delete your only verified number before adding and activating a new one, you risk losing your ability to recover your account if there are any future login issues.
Does changing your number affect your Google One subscription?
No, the subscription is tied to your payment profile and the account itself. However, if the number was used to pay through a mobile operator, the payment method will stop working and will need to be updated in the “Payments and Subscriptions” section.
