Have you ever tried to verify your Google account only to receive a message stating: “This phone number cannot be used for verification”? If so, you’re not alone. Many users experience this issue, and it can be frustrating when you’re trying to secure your Google account or regain access after being locked out.
There are several reasons why Google might reject your phone number for verification, ranging from security concerns to technical issues. In this article, we’ll explore the possible causes and provide practical solutions to help you successfully verify your account.
Possible Reasons Your Phone Number Is Rejected
Google has strict security measures in place to prevent spam, abuse, and fraudulent activity. Here are some of the most common reasons your phone number might not be accepted:
1. The Number Has Been Used Too Many Times
Google limits the number of times a single phone number can be used for verification. If you’ve used the same number to create or verify multiple accounts, you may receive a rejection message.
2. VoIP or Virtual Numbers
Many online services, including Google, do not accept VoIP or virtual numbers (such as those provided by Google Voice or apps like TextNow) for verification purposes. If you’re using one of these, try a physical mobile number instead.
3. Carrier Restrictions
Certain mobile carriers or regional policies may prevent Google from verifying your number. This is especially common with prepaid SIM cards or numbers from small, local providers.
4. Number Flagged as Suspicious
If Google detects unusual activity associated with your phone number (such as frequent account creation attempts), it may temporarily or permanently block it from being used for verification.
5. Technical Issues
Sometimes, simple technical issues like delayed SMS delivery, network connectivity problems, or an outdated Google app can prevent the verification process from working correctly.
How to Fix the Issue
If Google says your phone number cannot be used for verification, try the following solutions:
1. Use a Different Phone Number
If possible, try using another phone number, preferably one that has never been used for Google account verification before.
2. Wait and Try Again Later
Google can temporarily block numbers from being used for verification due to unusual activity. If you suspect this is the case, wait for 24–48 hours and try again.
3. Check Your Mobile Carrier
If you’re using a prepaid or VoIP number, consider switching to a postpaid mobile plan or a number from a different provider.
4. Ensure SMS Reception Is Enabled
Double-check that your phone can receive SMS messages. If you’re not receiving the verification code, try inserting your SIM card into another device.
5. Use a Landline (For Voice Verification)
In some cases, Google allows voice verification via a landline. If SMS verification isn’t working, look for the option to receive a voice call instead.
Preventing Future Verification Issues
To avoid encountering this issue again, consider taking the following precautions:
- Register Your Number with Google in Advance: Add your phone number to your Google account settings before any issues arise.
- Use Your Number Sparingly: Don’t use the same number to create multiple accounts in a short period.
- Keep Your Phone Plan Active: Ensure your mobile provider does not deactivate your number due to inactivity.
- Enable 2-Step Verification: This adds an extra layer of security and allows backup verification options.
Final Thoughts
Receiving an error message that your phone number cannot be used for verification can be discouraging, but in most cases, there’s a simple solution. By understanding the possible causes and following the suggested fixes, you can regain access to your Google account or set up verification successfully.
If none of the methods above work, you may need to contact Google Support for further assistance. With patience and persistence, you’ll be able to solve the issue and continue using your Google services without interruption.
