# Enabling a Landline Number

## Introduction

To enable a landline number, you'll need a mobile device to host your landline number (this option is available in WhatsApp Business). The step-by-step guide we created uses an Android phone.

### First step

Download the WhatsApp Business app on a mobile device

[Android]

[iOS]

[android]: https://play.google.com/store/apps/details?id=com.whatsapp.w4b

[ios]: https://apps.apple.com/us/app/whatsapp-business/id1386412985

***

### Second step

WhatsApp Business will request permission to access the device's files — choose "Continue" to grant access. On the next screen, select your country and enter your landline number.

***

### Third step

You'll receive a code, but since it's not possible to receive an SMS on a landline, wait until the countdown ends and choose the **Call me** option.

You'll receive a call from WhatsApp Business that will speak the activation code — just enter it in the indicated field ;)

### Fourth step

You're all set!

Configure the WhatsApp Business app and scan the Z-API QR code to give wings to your imagination!
