WhatsApp has become one of the most popular messaging apps worldwide, with over 2 billion active users. A key feature of WhatsApp is its end-to-end encryption, which helps keep conversations secure and private. To activate encryption, WhatsApp sends a 6-digit verification code when you register your phone number with the app. This code helps confirm your identity and set up the encryption keys. However, some users report issues receiving this 6-digit code, which prevents them from activating WhatsApp properly.
Common reasons you may not get the WhatsApp verification code
There are several potential reasons why you may not be getting the WhatsApp verification code needed to activate the app:
- Incorrect phone number entered – Double check you entered your full phone number correctly, including the country code.
- Poor cellular reception – Weak mobile network signals can prevent the code SMS from being delivered.
- Wrong messaging app – The code may have been sent to another messaging app by accident.
- SMS blocking – Some carriers or apps block automated verification messages like the WhatsApp code.
- Outdated WhatsApp – An outdated version of the app may have issues receiving the SMS code.
- Too many attempts – WhatsApp limits how many codes you can request per hour as an anti-spam measure.
- Banned number – Previously banned or deactivated numbers may not be able to receive new codes.
- Invalid number – Landline, VoIP, and some virtual/texting phone numbers cannot get SMS codes.
Below we explore these and other potential reasons in more detail, along with steps you can take to troubleshoot and fix the problem.
You entered the wrong phone number
The most common reason for not getting the WhatsApp verification code is that an incorrect phone number was entered when setting up the app. WhatsApp sends the 6-digit code as an SMS text message to the phone number provided. If there is even a small mistake in the number, such as an incorrect country code or missing digit, then the message won’t reach you.
To troubleshoot, open WhatsApp and carefully re-enter your phone number with the country code included. For example, a US number would be entered as +1XXXXXXXXXX. Double check that the full number is correct. If you recently changed phone numbers, be sure you input the new number rather than your old one accidentally.
Poor cellular reception is blocking the SMS
Since the WhatsApp verification code is sent as an SMS text message, you’ll need a cellular signal strong enough to deliver the text. If you’re in an area with poor reception, like a basement, elevator, or rural location, the SMS may fail to send. Switching your phone’s Airplane Mode on and off can sometimes help force a reconnection to the network.
Move to an area with better reception and request a new 6-digit code. You may need to wait outside or near a window temporarily to get a strong enough mobile network signal. This allows the SMS to send without any cellular communication issues interfering with the delivery of the text.
You input the number into the wrong app
When activating WhatsApp for the first time, it’s important to ensure you input the phone number directly into the WhatsApp app. Some users accidentally enter their phone number into the normal SMS text messaging app on their smartphone when attempting to set up WhatsApp. Since the verification code is intended to go specifically to the WhatsApp app, this mistake will prevent you receiving the actual code.
To fix this, open the WhatsApp app directly and carefully re-enter your full phone number when prompted. Triple check that you are entering your phone number into the WhatsApp app and not your regular text messaging app. This ensures the verification SMS is sent to the correct destination.
Your mobile carrier is blocking the code
Some mobile network carriers and third party apps intentionally block automated SMS messages like verification codes as an anti-spam measure. This can prevent the WhatsApp verification code from reaching you, even when your phone number is entered correctly.
Contact your mobile carrier to see if they are blocking the WhatsApp verification message. You may need to ask them to disable any filters that obstruct system text messages from WhatsApp or other companies. Alternatively, try temporarily disabling any third party apps that may block spam text messages before attempting to re-verify your number.
You have an outdated version of WhatsApp
To maintain optimal security and performance, WhatsApp frequently releases new versions of its app. However, some users neglect to update to the latest version. An outdated installation of WhatsApp may suffer from bugs that disrupt the SMS verification process.
Open your device’s app store (the Google Play Store for Android or App Store for iPhone) and search for WhatsApp. Check if there are any pending updates available for the app. Install the newest version of WhatsApp, then try re-verifying your number.
You’ve requested too many codes
To prevent spam and abuse, WhatsApp limits users to requesting a maximum of 5 verification codes per hour. If you’ve attempted to verify your number multiple times in a short window, you may have exceeded this limit.
You’ll need to wait an hour before you can receive another SMS with a new WhatsApp verification code. Set a timer or alarm for 60 minutes, do not attempt any further requests until the time is up. This resets the rate limit, allowing you to receive a new verification text.
Your number is banned from WhatsApp
WhatsApp will completely ban phone numbers that have violated their Terms of Service. For example, numbers implicated in illegal or abusive behavior may be banned. Once a number is banned, WhatsApp will no longer send the verification code to that problematic number.
You will need to acquire a new phone number not associated with your previously banned account. Enter your new number when installing WhatsApp to receive the verification SMS. Avoid behavior that led to your old number getting banned to maintain access to WhatsApp going forward.
You’re trying to use an invalid number
WhatsApp verification codes can only be sent to valid mobile phone numbers. Landline phone numbers will not work. You also cannot use virtual phone services, VoIP numbers, and some online texting apps to receive the SMS.
You’ll need to activate WhatsApp using a real mobile phone number directly associated with your physical cell phone. Virtual numbers get blocked from receiving the verification code for security reasons. Acquire a valid cell phone plan to properly use WhatsApp.
Your contact list is full
Most mobile phones can only store a finite number of contacts. In rare cases, having too many existing contacts can interfere with receiving new text messages like the WhatsApp verification code.
Try clearing out some old contacts you no longer need to make room for new entries. This may involve deleting contacts or moving them to your SIM card storage. With free space in your contacts list, retry receiving the WhatsApp verification message.
You have messaging blocking turned on
Some Android phones have an option to block all incoming messaging from unknown contacts. Since the WhatsApp verification code comes from an automated number not already in your contacts, it may get inadvertently blocked.
Go into your Messaging or SMS app settings and disable any options like “Block unknown senders” or “Spam protection”. This allows the incoming verification text from WhatsApp to be delivered. Remember to re-enable blocking when done if you want to continue filtering unwanted texts.
A mobile security app is blocking the code
Aggressive anti-spam apps and mobile security services can sometimes interfere with receiving important text messages. Overeager spam filtering may block the WhatsApp verification code, seeing it as unwanted text.
Try temporarily disabling any installed mobile security apps like cleaners, firewalls, or anti-virus services. Also whitelist the WhatsApp service in any app that lets you customize filters. With overactive spam blockers disabled, you should start getting the verification SMS.
Your phone lacks cellular service
In order for your smartphone to receive the WhatsApp verification code over SMS, it will require an active mobile data plan with texting capabilities enabled. The phone must be connected to a cellular network.
Ensure that your phone is currently connected to mobile data or WiFi with the ability to send and receive standard text messages. Contact your carrier to confirm your plan supports SMS. Alternatively, access WhatsApp verification through another phone number that has texting enabled.
You’re in Airplane Mode
When your phone has Airplane Mode activated, it cannot connect to any wireless networks, including your mobile carrier for SMS delivery. The WhatsApp verification code gets blocked while in Airplane Mode.
Pull down your notification shade and make sure the Airplane Mode toggle is disabled. If it was switched on, your phone should automatically reconnect to the mobile network when you deactivate Airplane Mode. This allows SMS messages to once again be received.
Do not disturb settings are blocking notifications
“Do Not Disturb” is an option on most phones that silences notifications during certain times or when enabled manually. This prevents notification sounds and vibrations to avoid disturbances. However, it can also unintentionally block incoming SMS messages.
Make sure your phone’s Do Not Disturb setting is disabled completely for now. Check your specific phone model for where to change this setting. With Do Not Disturb mode deactivated, all text notifications should once again alert on your phone.
You have connectivity issues
Any network connectivity problems that interfere with sending or receiving SMS messages could prevent delivering the WhatsApp verification code. Weak carrier signal, mobile network outages, and issues with your phone’s antenna can all cause disruption.
First toggle Airplane Mode on, wait 30 seconds, then disable Airplane Mode. This re-establishes the network connection. Try moving your phone closer to a window if nearby buildings are blocking signal. You can also temporarily switch cellular towers by inserting a different SIM card, such as a friend’s. Resolving any connectivity issues allows the verification code SMS to be received.
Steps to troubleshoot not getting the WhatsApp verification code
Based on the reasons explained above, here are systematic troubleshooting steps to help you get the 6-digit WhatsApp verification code:
- Ensure you entered the phone number correctly into WhatsApp, with the country code.
- Check for any carrier settings blocking the SMS code.
- Disable any messaging security apps temporarily.
- Try requesting a new code in a location with better cellular signal.
- Update to the latest version of the WhatsApp app.
- Use a different phone number not associated with a banned account.
- Confirm your mobile plan has texting enabled.
- Toggle Airplane mode off if it was switched on.
- Make sure Do Not Disturb permissions weren’t accidentally enabled.
- Contact your carrier if connectivity issues persist in your location.
Following these steps methodically can help identify and resolve the underlying cause of not getting sent the vital WhatsApp verification code. Most issues can be fixed within just a few minutes using appropriate troubleshooting.
Preventing problems with receiving the code
Once you get your WhatsApp verification code successfully, there are some precautions you can take to prevent future issues:
- Save the WhatsApp automated number into your contacts so messages aren’t blocked as easily.
- Regularly update WhatsApp to stay on the latest version with bug fixes.
- Enable auto-updates for your apps to receive new WhatsApp versions quickly.
- Make sure your carrier plan supports receiving standard SMS text messages.
