"This Phone Number Has Been Used Too Many Times"

"This phone number has been used too many times" means Google has hit its anti-abuse limit for that number: it has already been used for verification more times than Google allows, and Google doesn't publish the exact limit.
Google's own fix is to use a different number, such as one from a family member, a friend or a different carrier.

What this error means

Google's help page on verifying your account says it limits the number of times a phone number can be used for verification, to protect you from abuse.
When a number reaches that limit, Google shows "This phone number has been used too many times for verification" and asks for a different number.

The limit belongs to the number, not to your device, browser or account.
That's why changing those things doesn't clear it.

It isn't a ban and it doesn't mean your account is in trouble.
Google just won't send another code to that number.

How to fix it, step by step

  1. 1

    Stop retrying the same number

    The limit is on the number, so more tries, another browser or another device won't change the answer.

  2. 2

    Pick a different number

    Google suggests a family member's or friend's number, or a number from a different carrier.

  3. 3

    Or use a number just for this sign-up

    If you don't want someone else's number on your account, use a number for Gmail verification from SMS Falcon, paid by card or crypto.

  4. 4

    Choose the text option

    SMS Falcon numbers receive SMS only.
    If Google shows a QR code asking you to send a text, that step won't work with them.

  5. 5

    Enter the code and secure the account

    Type the code from your SMS Falcon account, then add a recovery email and a phone you'll keep long term.

"Phone number used too many times" FAQ

What does "This phone number has been used too many times" mean?

Google won't verify with that number again because it has reached Google's limit on verifications per number.
Use a different number.

How many accounts can one number verify?

Google doesn't publish the limit for Google accounts.
YouTube is the exception: a number can verify 2 channels per year.

Why does this happen on a number I've never used before?

Carriers recycle numbers, so a line that's new to you may have verified Google accounts under its previous owner.

Does waiting fix it?

Google doesn't say the count resets with time.
Its own advice is to use a different number, so don't count on waiting.

Does switching browser or device help?

No.
The limit is tied to the phone number, so a new browser, device or network gets the same answer.

Is this different from "cannot be used for verification"?

Slightly.
Google says "used too many times" is about how often a number verifies, while "cannot be used" is about how many accounts it has created.
The fix is the same: a different number.

Can a virtual number get the same error?

Yes.
Any number that has hit Google's limit gets it.
Google also refuses many VoIP lines, which is why non-VoIP numbers matter for Google.

Does this affect YouTube too?

YouTube has its own cap of 2 channels per number per year, with the message "This phone number has already created the maximum number of accounts".

Is there a way to reset the count?

No.
Google doesn't offer a reset.
The way forward is a number that hasn't reached the limit.

Can SMS Falcon guarantee a number was never used on Google before?

No, nobody can see Google's count.
If Google refuses the number or the code never arrives, the charge goes back to your balance automatically.
