Google says 'This phone number cannot be used for verification'

By the Noir SMS team3 min read

Quick answer

Google shows this message when it won't send a code to that number, usually because it's a VoIP or other line type it blocks, or because it's been used on too many Google accounts. It's not something you can fix by retrying. Use a different number, ideally a real mobile number. With a Noir SMS number, cancel after 2 minutes for a refund and try another one or another country.

Google blocks some numbers from verification to slow down bulk account creation. The message is blunt, but it tells you the problem is the number, not your device.

Why Google blocks a number

  • The number is VoIP or virtual in a way Google detects, such as many internet calling apps.
  • The number has been used to verify many Google accounts.
  • The number range is associated with abuse.
  • Google's risk checks flagged the sign-up for other reasons.

What to do

  • Use a different mobile number.
  • Try again later from a normal device and connection.
  • Skip the phone step if Google offers it.

Temporary numbers

Noir SMS numbers are mobile numbers from carriers, which Google usually accepts, but any number can be refused. Cancel after 2 minutes for an instant refund if no code arrived.

Frequently asked questions

Is this the same as 'used too many times'?

Similar. Both mean Google won't send codes to that number right now.

Does it mean my account is banned?

No. It's about the number.

Will a US number work better?

Any real mobile number can work. If one fails, try another country.

Can I still use Google without a phone?

Sometimes. Google decides whether the phone step is required.
