If WhatsApp is not sending a verification code to your Japan phone number, there could be several reasons behind this issue. Here are some common causes and troubleshooting steps to consider:
1. Incorrect Country Code
Make sure that you are entering the correct country code for Japan (+81). If you accidentally enter the wrong country code, WhatsApp won’t be able to send the verification code to your number.
2. Network Issues
WhatsApp sends the verification code via SMS or phone call. If there’s an issue with your mobile network, such as poor signal or network outages, you might not receive the code. Ensure that you have a stable network connection and try again.
3. SMS Blocked by Carrier
Sometimes, mobile carriers block certain types of SMS messages, including those from international services like WhatsApp. You can check with your mobile service provider to see if they are blocking verification codes from international numbers.
4. WhatsApp Servers or Service Outage
WhatsApp occasionally experiences service outages, which may delay or prevent code delivery. Check if WhatsApp is facing any temporary issues or service disruptions by visiting websites like.
5. Incorrect Phone Number Format
Ensure that you are entering your phone number in the correct format. For Japan, the number should look like this:
Example: +81 followed by your local number without the leading 0 (e.g., if your number is 090-1234-5678, enter it as +81 90 1234 5678).
6. Too Many Attempts
If you’ve tried to request the code multiple times in a short period, WhatsApp might temporarily block further requests to avoid spam. In this case, wait for a while (up to 24 hours) before trying again.
7. Blocked or Suspended Account
If you’ve violated WhatsApp’s terms of service in the past or if there are reports of spam from your number, WhatsApp may have blocked your number from receiving verification codes. Contact WhatsApp support for clarification.
8. Temporary Number Issues
If you're using a temporary or virtual number (such as one from a VOIP service), there’s a chance that WhatsApp may not send the verification code to such numbers. WhatsApp typically requires a real, working mobile number for verification.
9. Spam Filters or Security Settings
If your phone or service provider has spam filters or strict security settings, it may block messages from unknown senders, including WhatsApp's verification codes. Check your phone’s spam or security settings and ensure that messages from unknown sources are allowed.
10. WhatsApp Version
Ensure that you have the latest version of WhatsApp installed on your phone. Outdated versions may experience issues during verification.
What You Can Do:
Double-check the phone number and country code.
Restart your phone or toggle airplane mode to reset network connections.
Wait for some time before trying again, especially if you've made several requests for the code.
Contact your mobile carrier to ensure that there are no restrictions on receiving international SMS messages.
If everything else fails, reach out to WhatsApp Support for assistance.
