Google Rejects Your Phone Number Before Sending a Code: Why It Happens
Key takeaways
A number rejected before an SMS is sent is a different problem from a missing message. If Google rejects the number immediately, checking your phone’s spam folder will not help.
Google limits how many accounts can be created and how many verifications can be completed with one phone number. Its help pages do not specify exact limits.
A new number can be rejected too. Buying a SIM or renting a number does not mean Google will accept it.
“This phone number cannot be used,” “Too many attempts” and “Carrier not supported” point to different restrictions.
To recover an existing account, use the verification methods offered on screen. You cannot substitute another number at every stage.
You enter your number, click Next and immediately see an error. You never even reach the code entry screen. The number works and receives messages from other services, but Google will not accept it.
After a few retries, you might feel like buying another SIM, switching browsers or starting the registration again. Before changing anything, read the error itself. It can help you work out whether Google rejected the number, limited your attempts or reported a problem sending the message.
Did Google reject the number, or did the SMS simply fail to arrive?
Look at what happened after you clicked the button.
| What appears on screen | Where to start |
|---|---|
| “This phone number cannot be used for verification” | Check the number’s format, then use another number as Google recommends |
| “This phone number has been used too many times” | Use another number |
| “Too many attempts. Try again later” | Stop retrying and wait for the period shown on screen |
| A message about an unsupported carrier | Try a number from another carrier |
| A code entry field and a message saying the code was sent | Check SMS delivery and whether the number can receive messages |
If Google immediately says the number cannot be used, waiting for a message will not change anything. Once the form moves to the code entry screen, the questions are different: is the SIM working, is the carrier experiencing a delay, and was the message sent to the right number?
The number has been used for verification too many times
Google’s help pages say it limits both the number of accounts created with one phone number and the number of times that number can be used for verification. This is part of its protection against abuse. For errors about an unusable number or too many uses, the help pages suggest using another number, including one from a different carrier.
However, they do not give a universal figure such as “five accounts per SIM.” Nor is there a published waiting period after which every number becomes eligible again.
If you have verified several accounts with the same number, the likely reason seems clear. But “This phone number cannot be used” does not show the number’s verification history or explain exactly which restriction was triggered.
Removing the number from an old account’s settings does not promise a fix either: Google does not describe this as a way to reset the verification limit.
Why a brand-new SIM can be rejected
You have just bought the number and have not entered it anywhere yet, but Google already displays an error. This happens with regular mobile carrier SIMs too.
On Reddit, you can find discussions about new numbers being rejected and the same error appearing with several numbers in a row. Sometimes another number works; sometimes the form keeps rejecting every option. Those posts cannot establish the cause of each rejection, but they show why buying yet another SIM does not always solve the problem.
“I have never used this number before” describes your experience. It does not reveal how Google assesses the number or the current verification request.
A single rejection also does not mean the number is permanently blocked or that other services will reject it.
Google says your carrier is not supported
This error is more specific: the service says it does not currently support sending messages to your carrier and suggests another one.
Two numbers on the same network may produce the same result. If you try a replacement, use a number from a different carrier. Even that attempt can fail, though: Reddit discussions include reports of the error continuing after such a switch.
A number that receives SMS messages from a bank or shop is still working. The problem occurs specifically during Google verification.
If you contact the number provider, send the exact error text. “The code is not arriving” and “Google will not accept the number” describe different problems to a support team.
Too many attempts, even though no code has arrived
The attempts warning can appear even if you have not received a single SMS. Not receiving a code does not mean the service has not recorded verification requests.
Some people report being able to continue after two days; others say the error lasted longer. Advice such as “wait exactly 24 hours” or “everything resets after a week” does not always work.
If Google tells you when to try again, follow that message. If no time is given, there is little point in retrying every few minutes: those attempts do not tell you anything new.
After a break, make one attempt and note the result. If you change the number, device, browser and connection all at once, you will not know which change helped.
What to check in the phone number itself
You can fix a formatting error without buying a new SIM.
The country selected in the form must match the number’s country code. If the code is already selected in a separate dropdown, entering it again in the number field can create an invalid entry. Check the entire number too, looking for missing digits or an extra domestic dialing prefix.
If you rent a number, its SMS reception period must still be active. But extending the rental will not make Google accept a number it rejects before sending a code.
A data-only eSIM will not solve this either. It provides internet access, but it does not replace a phone number that can receive SMS.
Will another browser or a VPN help?
Switching browsers does not reset Google’s documented limits on phone number use. A new IP address does not make an ineligible number eligible either.
For recovery of an existing account, Google recommends a familiar device, your usual browser and a location where you have signed in before. If you normally use your email on your laptop at home, start the recovery process there using the same browser.
One error message is not enough to prove that a VPN, or a mismatch between the number’s country and your connection’s location, caused the problem. Promises such as “use an IP address from the right country and the code will be sent” do not address number limits or carrier restrictions.
Creating a new account versus recovering an old one
When you create an account, Google sometimes offers the option to enter another number. In that case, you can replace it directly in the form.
During account recovery, the service may ask for a specific number previously linked to the account. A newly purchased number cannot replace it: that number does not prove you have access to the existing account.
| What Google asks for | What to do |
|---|---|
| A number for verification during registration | Use a number the form accepts and that you can access |
| A code sent to a previously added number | Receive the message on that number or use an alternative method offered on screen |
| Verification through another device | Complete the action on the device Google specifies |
| Account recovery | Use the official account recovery form |
The “Try another way” button only shows the options available for the current verification step. One account may offer a recovery email, another a prompt on a phone, while a third may have no alternative at that stage.
Can you use a Revosim number?
The Revosim SMS verification numbers section includes an option for Google, YouTube and Gmail. Before getting a number, check the available countries, the SMS waiting period and the order terms.
You can try one of these numbers when Google allows you to enter another number for verification. Google decides whether to accept it. If the form rejects the number immediately, there is no point waiting for a code: your Revosim dashboard will offer a replacement number.
If you plan to keep using Google services, a one-time activation is not a suitable long-term option, as Google may ask you to verify the number again in the future. For work email, documents and important accounts, consider renting a virtual number with monthly or annual billing. Revosim also offers a US eSIM with a phone number.
What to do after a rejection
Start with the exact message on screen. Check the number’s format. If you have hit an attempt limit, take a break. If Google suggests another number, try a replacement while paying attention to the carrier. When recovering an existing email account, stay in the recovery process and use a familiar device.
The frustrating part is that the number works, yet you get almost no explanation. But you do not have to buy several SIMs in a row and keep clicking Next. First, work out which verification step you are on and what Google actually rejected. That will help you decide what to do next and, once you are signed in, get back to the email you wanted to use in the first place.
