WhatsApp Not Sending Verification Code: Causes and Quick Fixes

Are you trying to log into WhatsApp but receiving an error message stating that the verification code wasn't received? Don’t worry—this situation is quite common and can be easily resolved. This article will help you understand the causes of this error and provide simple solutions, so you can continue using WhatsApp without any issues.

What Is the WhatsApp Verification Code For?

The WhatsApp verification code is a 6-digit number sent to your phone, used to register or log into your account. This security code verifies your identity, preventing unauthorized access to your account.

Some specific instances where a WhatsApp verification code is required include:

• Registering a new account.
• Logging into WhatsApp on a new device.
• Restoring a locked WhatsApp account.
• Changing your WhatsApp phone number.

Why isn’t WhatsApp sending the verification code?

Here are some reasons why WhatsApp may not be sending the verification code to your phone:

1. Phone Is in Airplane Mode

While your phone may be connected to Wi-Fi, it cannot receive text messages when in airplane mode. Many users overlook this, leading to the inability to receive the verification code.

2. Phone Is Blocked for Outgoing Messages

If your phone number is blocked for outgoing messages, WhatsApp cannot send the verification code to you. Contact your mobile carrier to resolve this issue.

3. Incorrect Phone Number

If you enter the wrong phone number, even by a single digit, WhatsApp cannot send the code. Ensure that you enter your phone number correctly, including the country code, to receive the verification code.

4. Logged in on Multiple Devices

WhatsApp has a security policy limiting the number of devices you can log into simultaneously. If you attempt to log into multiple devices, the system may suspect unauthorized access, temporarily preventing you from receiving the verification code via SMS.

5. Previous Verification Not Completed

In some cases, if you did not complete a previous verification or if the process was interrupted, WhatsApp will not send another code until the previous verification is completed.

6. WhatsApp Maintenance

During maintenance or updates, WhatsApp’s services may be temporarily disrupted, including the sending of verification codes. However, maintenance usually lasts only a short time, so there’s no need to worry.

7. Verification Code Limit Reached

WhatsApp imposes a limit on the number of verification codes sent within a certain period to prevent fraudulent activity. If you request too many codes in a short time, WhatsApp will stop sending them, and your account may even be locked.

8. Unstable Internet Connection

WhatsApp requires an Internet connection to function, including sending verification codes. An unstable connection may prevent you from receiving the code promptly.

9. Phone Security Settings

If your phone’s security settings block messages from unknown numbers, you may not receive the WhatsApp verification code. Adjust your security settings or choose to receive the code via a phone call instead.

10. Incorrect Phone Number Format

WhatsApp’s messaging system is automated and can only recognize correctly formatted phone numbers. If you enter an incorrect international format (e.g., +84 for Vietnam) or include spaces, you will not receive the code via SMS.

How to Fix WhatsApp Not Sending the Verification Code

Based on the causes mentioned, here are a few quick solutions to fix the issue:

• Check airplane mode and your network connection to ensure stability.
• Re-enter your phone number correctly, without spaces or special characters.
• Update the app to the latest version, or try requesting the code again after some time.
• Contact WhatsApp support if you’ve tried everything and still haven’t resolved the issue.

The causes of WhatsApp not sending verification codes have been summarized here, along with quick fixes to help you address this issue.
