What should I do if I don’t receive the SMS verification code when logging in?

If You Are Not Receiving the WeChat Verification Code via SMS, Please Check the Following:

1. Check whether your current mobile number matches the one originally linked to your WeChat account.
   If you’ve changed your phone number, try logging in using another method and update your linked number as soon as possible.

2. Make sure your phone can receive other SMS messages normally.
   If you’re not receiving any SMS messages, it could be due to poor network conditions or because your number is roaming, out of credit, or suspended.

   • If it’s a network issue, try logging in again after 30 minutes.

   • If your number is unavailable due to billing issues, contact your mobile carrier for assistance.

3. Check if your phone has security software installed with SMS blocking enabled.
   If so, we recommend temporarily disabling the blocking feature and then requesting the verification code again.

4. Consider whether you've previously requested your carrier to block WeChat’s SMS sender number or added it to a blacklist.
   For example, you may have sent messages like “Stop,” “Unsubscribe,” or “Cancel” to that number.

   • If you’re unsure, contact your carrier to verify and request the removal of any blocks.
