WhatsApp typically requires a phone number to create and verify an account. Most users register using a mobile number, but many people may not realize that it is also possible to use a landline number for WhatsApp registration.

This option is particularly useful for businesses or individuals who want to keep their personal mobile number private while still communicating through WhatsApp. By using a landline number, users can create an account through the WhatsApp Business app, which supports verification via voice call.

Below is a step-by-step guide explaining how you can use WhatsApp with a landline number and maintain better privacy.

Why Use a Landline Number for WhatsApp?

Using a landline number instead of a personal mobile number offers several advantages.

Some of the main benefits include:

• Better privacy by keeping your personal number hidden




• Professional communication for businesses or offices




• Ability to separate personal and business conversations




• Access to extra features in the WhatsApp Business app

This method is commonly used by companies that want customers to contact them through a fixed office number.

Requirements Before You Start

Before setting up WhatsApp with a landline number, make sure you have the following:

• A working landline phone number




• A smartphone to install the app




• Access to the WhatsApp Business app




• Ability to receive a voice call on the landline

Since landline numbers cannot receive SMS messages, verification will happen through a phone call instead of text message.

Step-by-Step Guide to Use WhatsApp with a Landline Number

Follow these steps to register your landline number with WhatsApp.

Step 1: Install WhatsApp Business

Download and install the WhatsApp Business app from your device’s app store.

Step 2: Enter Your Landline Number

When the app asks for a phone number, enter your landline number along with the country code.

For example, in India:

• Country code: +91




• Enter the landline number with the STD code but without the leading zero

Example format:
+91332654XXXX

If you are unsure about the correct format, try calling a mobile phone from the landline and note how the number appears.

Step 3: Wait for SMS Verification to Fail

WhatsApp will initially attempt to send an SMS verification code. Since landline numbers cannot receive SMS, the verification will fail.

Step 4: Select “Call Me” Option

After the SMS attempt expires, select the “Call me” option for verification.

Step 5: Receive the OTP via Call

WhatsApp will call your landline number and provide the verification code through an automated voice message.

Step 6: Enter the Verification Code

Type the OTP into the app and complete the setup process.

Once verification is complete, your WhatsApp Business account will be active using the landline number.

Things to Know When Using WhatsApp with a Landline

While this setup works well, there are a few limitations.

For example:

• Contacts may need to be added manually in some cases




• The account must be used through the WhatsApp Business app




• SMS verification will not work, only voice call verification

However, the business version of WhatsApp also includes useful tools such as:

• Automated replies




• Business profile information




• Message organisation tools

These features can help users manage conversations more efficiently.

A Useful Option for Privacy and Business Communication

Using WhatsApp with a landline number can be a practical solution for people who want to keep their mobile number private while still communicating through the platform.

Whether you are running a business, managing customer queries, or simply prefer separating personal and professional communication, this setup offers a flexible way to use WhatsApp without relying on your personal phone number.
