You can link up to five devices to the WhatsApp Business app. But if you want to add more users, you have to use the WhatsApp API with communication software.

WhatsApp Business for Multiple Users: A Guide for App & API

Whether it is your buyers, prospects, you, or me, all of us want a quick reply from a company we sent a message to. That is the reason why companies have started using WhatsApp Cloud API and its business app to fulfill this demand.

Be it its usability or user interface, businesses both big and small are using WhatsApp marketing to answer customers' issues and reach out to new ones as well.  

Although it might sound that WhatsApp is the ultimate communication platform, it has its limits too. And that is the number of devices or people who can use it at once. Since WhatsApp uses a verification process that only allows it to be used with only one phone number, it is somewhat difficult for multiple users to use it simultaneously.

That’s why in this article, I will tell you about how you can use WhatsApp (both app and API) on multiple devices. I will also go over how you can add more users to your WhatsApp business account as you expand your business and grow your team. So let’s start by understanding the different variations that WhatsApp offers and how you can use them on multiple devices and develop your WhatsApp business marketing strategies.

WhatsApp Business app

WhatsApp offers two variations of its service, a Business app, and an API. Both of these require a phone number for using them. I’ll explain the Business app first. 

WhatsApp Business app is created by taking into account the needs of startups or small-size companies that have a handful of team members. This makes it a preferable choice for small businesses because it's free and allows you to leverage WhatsApp reach for sales engagement. It is so famous that, according to WhatsApp, 50 million companies use it around the globe.

That was not always the case. Until last year, the Business app could only be used on a single phone and a desktop computer. But after the changes implemented by WhatsApp last year, now you can connect the WhatsApp Business app to a maximum of five devices, consisting of one smartphone and four additional devices (tablets or PCs).

This way, up to five people can use the same Business account across multiple devices. Which is perfect for businesses with small teams. With that said, let’s see how you can connect multiple devices to your WhatsApp Business app.

How to use the WhatsApp app on multiple devices?

Below are the steps to link additional devices to the original phone which has a WhatsApp Business app installed and set up. 


If you have an Android device, follow these steps to connect more devices:

Open the WhatsApp Business app and click on the three dots at the top right corner and select the Linked devices option.

On the next scream, click on the Link a device button and enter the PIN or unlock your phone with biometrics based on the type of screen lock you use.

Finally, scan the QR code with your phone which is displayed on the screen of the device you want to connect to. And you are done. If you are using an iOS device, you can follow the same steps to link multiple devices with your Business app.

WhatsApp Business API

Now, if you are a startup or if you have a small team, you can be more than happy with the WhatsApp Business app. But, if you want more than five users active at the same time, the Business app is not a choice for you. 

Also, when your business grows, so will the number of customers and team members. In that case, you will come across a few issues when utilizing the connected devices. These problems can include:

  • Unable to find out which member responded to a message since you are using one account on multiple devices. 
  • You cannot measure how well your reps are performing or how much work a rep is doing.

Big companies that have complex processes in place require a robust platform with advanced functionalities to handle WhatsApp messaging to boost customer engagement and drive sales. And to do that, you have to use WhatsApp business platform API integrated with a sales engagement platform like Zixflow.
