“This Phone Number Cannot Be Used for Verification”
Google shows this when a number has already verified too many accounts or belongs to a range of virtual numbers. Other services show similar errors for the same reasons.
By the editorial team · Updated · 4 min read · What changed- The error is about the number, not your account.
- Google refuses many virtual and overused numbers.

Google shows “This phone number cannot be used for verification” when a number has verified too many accounts or belongs to a virtual number range. The message is about the number, not your account. This guide explains both causes, what doesn’t help, and the options that do — from skipping the phone step to using your own number or a private non-VoIP one.
For: People blocked by Google’s phone verification step.
Covers: Why the error appears and which numbers pass.
Not covered: Locked or disabled Google accounts — use Google’s account recovery.
Key terms: VoIP number, Non-VoIP number, Carrier lookup
What “Cannot Be Used for Verification” Means
Google shows this error when it decides a number is unsafe for a new account: it has verified too many accounts, it belongs to a VoIP range, or the format is wrong. The table below shows how to tell which cause applies and what fixes it.
| Cause | How to tell | Fix |
|---|---|---|
| The number verified too many accounts | Shared or popular numbers, error on the first try | A number that hasn’t verified accounts before |
| The number is VoIP or virtual | The error appears on every free number you try | A mobile carrier SIM |
| Format or country problem | “Invalid” rather than “cannot be used” | Check the format |
What Won’t Fix the Error
Switching browsers, devices or retyping the number. The check runs on the number itself, before any code is sent. Trying many numbers quickly can add a “too many attempts” block on top.
How to Get Past Google Phone Verification
The number type matters more than the browser or device. Your own SIM always works, a private non-VoIP number usually works for a one-time sign-up, and free shared numbers rarely pass Google. Choose by whether you plan to keep the account.
- 01For an account you’ll keep, use your own number, then set up a recovery email and two-step login.
- 02For a one-time sign-up, use a private non-VoIP number: it’s a real mobile SIM that hasn’t verified other accounts.
- 03Free numbers rarely pass Google. Its success rate is low in the success table; if you try one, pick the freshest.
- 04Check whether the phone is optional. Some Google sign-up flows let you skip the phone step. If “Skip” is there, you don’t need a number at all.

Google Phone Verification FAQ
Does this error mean my account is banned?+
No. It refers to the number, not your account. The sign-up can continue with a different number. Nothing is stored against you, and you can finish sign-up with a different number. If every free number shows the error, Google is refusing virtual numbers for that sign-up; try your own SIM or a private non-VoIP number.
How many accounts can one phone number verify on Google?+
Google doesn’t publish the limit. It’s the reason popular shared numbers get this error even when they’re otherwise fine. Shared numbers hit the limit quickly because many people use them, so even a fresh-looking free number can fail. A number that has never verified a Google account passes more often.
Will Google Voice or another app number work?+
Often not: they are VoIP numbers, and Google refuses many of them for verification. Google can detect internet phone numbers during a carrier lookup. A private non-VoIP number on a real mobile SIM, or your own number, passes far more often.
Can I create a Gmail account without a phone number?+
Sometimes the phone step is optional, depending on the device and the sign-up flow. If there’s no skip option, you’ll need a number that passes the check. Signing up on a device where you are already logged in to another Google account sometimes changes which checks appear.
Other sites show the same error. Is it the same problem?+
Usually yes: the number is overused or virtual. The fixes are the same: a fresh number for loose sites, a carrier SIM for strict ones. Read the exact wording: “invalid” usually means a format problem, while “cannot be used” means the number itself is refused.
