"This phone number cannot be used for verification" on Google
What Google means by this message, why a number gets refused, and which kind of number gets the verification code through.
When you create a Google account or verify one, Google may answer with "This phone number cannot be used for verification". It does not say why, but the reasons are well known.
Why Google refuses a number
- The number has already verified many Google accounts.
- It is an internet calling number (Google Voice, TextNow and similar apps), which Google often does not accept for verification.
- Too many attempts in a short time from the same connection.
- The number belongs to a range Google treats as risky.
What helps
Wait a while before trying again, and use a real mobile number from an operator, not an app number. If you do not want to give your own number, a temporary operator number works the same way: you enter it on Google and read the SMS code on the page.

| Slovenia | 84% | $1.10 |
| Angola | 83% | $1.25 |

Success over the last hour, refreshed when you open the page.
One thing to know
Google may ask for a code again later, for a new device or a password reset. A temporary number is used once, so add a recovery email and a second sign-in method to the account right after verifying.
FAQ
Does waiting help?
Often, yes. Several attempts in a row can block a number for a while. Try again later or with another number.
Why is my Google Voice number refused?
Google limits verification with internet calling numbers. A real operator number is accepted far more often.
