You wait for your WhatsApp SMS number verification code, but nothing arrives. It feels frustrating, especially when your business depends on WhatsApp. Many people ask, “why am i not getting a whatsapp verification code?” Sobot and Sobot AI help you with troubleshooting so you can keep customer chats running smoothly.

Why Am I Not Getting a WhatsApp Verification Code

Common Causes

You might wonder, “why am i not getting a whatsapp verification code?” This happens to many people. There are several reasons why whatsapp not sending verification code. Sometimes, you enter the wrong phone number or forget the country code. Other times, your internet connection is weak, so the code is not received. If your device blocks SMS from unknown numbers, the whatsapp sms number can’t reach you. Some users find that their phone receives codes from other apps, but not from whatsapp. This shows the issue is specific to whatsapp.

Here are some common reasons why whatsapp not sending verification code:

You typed the wrong phone number or missed the country code.
Your phone has a poor network connection.
The verification code is blocked by your device or carrier.
You use a VoIP or virtual number, which whatsapp does not support.
Too many verification attempts can cause a temporary block.
Your whatsapp app or phone system is not up to date.
The code is not received because of carrier restrictions, especially with new or international SIMs.

Tip: Try toggling Airplane mode, checking for app updates, or using the “Call Me” option if the code is not received.

How WhatsApp SMS Number Verification Works

The Verification Process

When you set up WhatsApp, you need to prove that you own your phone number. This is where the WhatsApp SMS number comes in. The app sends you a unique code by SMS. You enter this code into WhatsApp to finish the setup. Here’s how the process usually works:

Get a phone number that is not a VoIP number.
Type your phone number into WhatsApp.
Wait for the SMS with your verification code.
Enter the code into WhatsApp.
Complete your account setup.

Most people finish this process in just a few minutes. Sometimes, you might face a WhatsApp verification code problem, like not getting the code or the code expiring. If this happens, check your phone number and network. Paid services report a 99% success rate for verification, while free services often fail because WhatsApp blocks them for security reasons. You can read more about these stats on Plivo’s blog.

Tip: Always use a stable network and make sure your number is not already linked to another WhatsApp account.

Fix WhatsApp Not Sending Verification Code

Running into a WhatsApp verification code problem can feel stressful, especially when you need to get started quickly. Let’s walk through simple steps to fix WhatsApp not sending verification code issues, so you can get your whatsapp sms number verified and keep your business moving.

Check Phone Number and Country Code

The first thing you should do is check your phone number and country code. Many people enter an incorrect phone number or forget the country code, which leads to not sending verification code problems. WhatsApp needs your number in the international E.164 format. This means you should include the country code and only use digits—no spaces or symbols.

Here’s what you can do:

Double-check your phone number before you hit submit.
Make sure you add the correct country code at the start.
Look for any missing digits or typos.
If you’re not sure, try searching for your country’s code online.

Tip: If you enter an incorrect phone number, the code will go to someone else. Always check your phone number and country code before you try again.

Standardizing your number helps avoid the whatsapp verification code problem. Some APIs, like Wassenger, even let you check if a number exists on WhatsApp before you try to verify. This step can save you time and frustration.

Network and SIM Issues

Sometimes, the problem isn’t with WhatsApp at all. Your phone’s network or SIM card can cause issues with not sending verification code. If your phone has a weak signal or your SIM is new, you might not receive the code.

Try these steps:

Restart your phone to refresh your network connection.
Move to a spot with better signal.
Make sure your SIM card is active and can receive SMS.
If you’re using a virtual number or VoIP, switch to a regular mobile number. WhatsApp does not support virtual numbers for verification.

If you’re still waiting for sms or call, don’t panic. Sometimes, network delays mean the code is not received right away. Wait for the sms or call for at least 10 to 15 minutes before trying again. This helps avoid temporary restrictions from too many attempts.

App Updates and Permissions

Outdated apps or blocked permissions can also cause WhatsApp not sending verification code issues. If your WhatsApp app is not up to date, it may not work well with your phone’s system. Also, if you block SMS permissions, the code will not be received.

Here’s how to fix WhatsApp verification code problem related to your app:

Update WhatsApp to the latest version from the app store.
Check your phone’s settings to make sure WhatsApp can receive SMS.
On Android, clear the WhatsApp cache to remove any temporary glitches.
If you still have issues, uninstall and reinstall WhatsApp.

Note: Always allow WhatsApp to access your SMS and notifications. This helps you get the code without any trouble.

If you’re waiting for sms or call and nothing comes, try the “Call me” option. WhatsApp will call your number and read the code out loud. This is a great way to fix WhatsApp not sending verification code when SMS is not received.

Fix WhatsApp Verification Code Problem When Traveling or Changing SIM

International Number Issues

Traveling can make it hard to get your WhatsApp verification code. If you use an international number, you might find the code not received. Some countries block certain SMS messages, so the code is not sending verification code to your phone. Roaming charges or weak signals also cause issues. You may notice delays or never get the code at all. Always check if your phone can receive SMS in the country you visit. Try switching to a local SIM if you keep having problems. If you use Sobot’s WhatsApp API, you can manage numbers from different countries in one place. This helps you fix WhatsApp verification code problem faster, even when you travel.

SIM Swap and Porting

Changing your SIM or porting your number can lead to not sending verification code problems. Sometimes, scammers use tricks to steal your number. Here’s what can happen:

Criminals gather your personal info through phishing or data leaks.
They pretend to be you and ask your mobile provider to move your number to a new SIM.
Your phone loses service, and you cannot get calls or SMS, including WhatsApp verification code.
The scammer now gets your codes and can access your accounts.

SIM swap scams have jumped by 240% in 2024. Most people do not know until their phone stops working and codes are not received. If you see “SOS-only” on your phone, act fast. Contact your provider right away. For extra safety, use app-based two-factor authentication instead of SMS codes. You can read more about SIM swap fraud here.

Best Practices

You want to avoid problems with your whatsapp sms number, so it helps to follow some simple steps. Keeping your phone and messaging apps updated gives you the latest security features. This makes it easier for whatsapp to send codes without trouble. Always check your SIM card status and make sure your message center number is set right.
