Can you use a landline number with WhatsApp? Learn how landline verification works, what features are available, and when virtual landline numbers can support WhatsApp calls.

Can you register WhatsApp with a landline number?

Yes, you can register WhatsApp with a landline number. While WhatsApp is typically associated with mobile numbers, the platform also allows users to create an account using a landline. The main difference is how the verification process works.

Normally, WhatsApp sends a six digit verification code via SMS. Because landline numbers cannot receive text messages, this method will not work. Instead, WhatsApp provides a voice verification option. After the SMS attempt fails, you can choose the “Call me” option, and WhatsApp will place an automated phone call to the landline that reads out the verification code.

Once the code is entered into the app, the WhatsApp account becomes fully active and can send and receive messages like any other account.

This method also works for WhatsApp Business but instead of failing the SMS verification the first time you can verify using the voice call method immediately as the option to do so is given from the start.

However, there is an important limitation to understand. A traditional landline cannot receive WhatsApp calls because the phone itself does not run the WhatsApp application. It can still be used for WhatsApp messaging, but voice and video calls only work on devices that have the app installed.

One way around this limitation is to use a virtual landline number that forwards calls to a mobile device. With this setup, the WhatsApp account is registered using the landline number, while the mobile device running the app can handle both messages and WhatsApp calls.

How to register WhatsApp with a landline number

Setting up WhatsApp with a landline number is straightforward once you understand the verification process.

Step 1: download and open WhatsApp

Install WhatsApp from the Google Play Store or Apple App Store. Once installed, open the app and begin the account registration process.

Step 2: enter the landline number

Enter your landline number exactly as you would any other phone number. Make sure to include the correct country code. For example:

  • +44 for the United Kingdom
  • +1 for the United States
  • +61 for Australia

The format should always be the international version of the number.

Step 3: wait for the SMS verification attempt

After entering the number, WhatsApp will attempt to send an SMS verification code. Because the number is a landline, the SMS message will not be delivered. This is expected and part of the process.

Step 4: choose the “Call me” verification option

Once the SMS attempt fails, WhatsApp will present an option to receive the verification code via a phone call. Select the “Call me” option to continue.

Step 5: receive the automated phone call

WhatsApp will place an automated call to the landline number. During the call, a recorded voice will read out a six digit verification code. Make sure someone is available to answer the call and write down the code.

Step 6: enter the code to complete registration

Enter the six digit code into the WhatsApp app to verify the account. Once the code is accepted, the WhatsApp account will be fully activated and ready to use.

Using a landline number with WhatsApp Business

Verification is slightly easier

If you are registering with WhatsApp Business, the verification process is more straightforward. WhatsApp Business will offer the call verification option immediately, meaning will not need to wait for the SMS attempt to fail before choosing the voice call option.

Why businesses often use landline numbers

Many businesses prefer using a landline number for WhatsApp because it keeps all customer communication connected to the company's official contact number.

This can help build trust and make it easier for customers to reach the business. Instead of advertising multiple phone numbers, companies can use the same number for both traditional calls and WhatsApp messaging.

What you can and cannot do with a landline WhatsApp number

What works normally

Once the account is verified, most WhatsApp features work the same way as they do with mobile numbers. You can:

From a messaging perspective, there is no difference between a landline WhatsApp account and a mobile one.

Limitations of landline WhatsApp numbers

The main limitations come from how traditional landlines operate.

A physical landline cannot run the WhatsApp app itself. The app still needs to be installed on a smartphone or computer. Therefore, traditional landlines cannot directly receive WhatsApp voice calls or video calls as WhatsApp calls can only happen between one WhatsApp user and another.

The exception: virtual landline numbers

There is an important exception to this limitation, virtual landline numbers.

Instead of being tied to a fixed phone on a desk, virtual landline numbers operate through cloud telephony. This means they can be configured to forward incoming calls to another device, such as a smartphone.

Because the calls are routed to a mobile device running WhatsApp, the user can receive both WhatsApp messages and WhatsApp calls while still using a landline style number. In practice, this allows a business or individual to keep a professional landline number while managing communication through the WhatsApp app on their mobile device.

This is where services like gosimless are useful. gosimless provides virtual landline numbers that support call forwarding, allowing incoming calls to be routed to a mobile phone. This setup makes it possible to use a landline number on WhatsApp while still being able to receive messages and WhatsApp calls through the device running the app.

Frequently asked questions

No. WhatsApp's architecture requires a unique phone number for each account. If you register your landline with the standard WhatsApp app and then later try to register it with WhatsApp Business, the system will prompt you to migrate the number. Once migrated, the original account will be deactivated. If you need both, you will need two separate landline or virtual numbers.

If you lose access to the landline, you can still use the WhatsApp app on your smartphone as long as you don't log out or change devices. However, if you get a new phone or need to re-verify your account, WhatsApp will trigger the "Call me" process again. Without the ability to answer that landline, you will be locked out of your account. This is why many users prefer virtual landline services, as the "phone" exists in the cloud and can be accessed from anywhere.

Yes, but you must first set up the account on a mobile device (smartphone or tablet) using the landline verification process. Once the account is active on a mobile device, you can use the "Linked Devices" feature to sync it with WhatsApp Web or the Desktop app. You cannot create a brand-new account directly on a computer using a landline.

No. This is a common point of confusion. Using a landline for WhatsApp only allows you to receive WhatsApp-to-WhatsApp messages. Standard SMS messages (like bank alerts or verification codes from other apps) are not supported by UK landline numbers.

Yes. WhatsApp allows users to change the phone number associated with an account. Using the Change Number feature in WhatsApp settings, you can move your account from a mobile number to a landline number as long as you can complete the verification process.

Yes, virtual numbers can be used for WhatsApp verification if they are able to receive voice calls. Businesses commonly use virtual numbers to verify WhatsApp Business accounts, especially when the number includes call forwarding or cloud telephony features.
