How to use WhatsApp Business with second number

In recent years, more and more companies have integrated WhatsApp Business into their customer communications and have mostly had very positive experiences with it. In combination with an increased presence on social media, communication via WhatsApp Business leads to a closer relationship with the consumer and thus to better sales figures and personal customer service, the testimonials show. In addition, studies found that the open rate of WhatsApp messages is 98%, significantly higher than emails (about 20%) (source: AiSensy.com). Thus, there are many good reasons to use a WhatsApp corporate account for customer communication. However, with a single phone number, it is often difficult to efficiently handle all the requests from customers. Fortunately, there is an option to add multiple numbers to your WhatsApp business account to further organize and simplify your customer communications.

‍

Reasons for multiple WhatsApp numbers

Multiple numbers for your WhatsApp business account can offer many benefits. Here are some of them:

Separate communication: By adding a second number, you can maintain separate communication with customers. This is especially helpful if your company has different departments or locations, or operates in multiple industries.
More efficiency: With a second number, you can process customer inquiries faster, as you can split them among different numbers and thus keep track of them.
Professionalism: A second number shows your customers that you care about their needs and want to provide them with a better customer experience.

‍

Ways to add more WhatsApp phone numbers

There are several options to add more WhatsApp phone numbers. All options have their own advantages and disadvantages. It doesn't matter if the added number is a mobile number, a landline number or possibly the number of the second SIM card in the cell phone.

‍

Option 1: Install WhatsApp and WhatsApp Business at the same time

This option does not allow you to be reachable via WhatsApp Business on multiple numbers, but at least you can use a WhatsApp Business account on the same device on which your private WhatsApp account is already installed - and with a different phone number.

Prerequisite: You already have a private WhatsApp account on your smartphone

‍

1. download and install WhatsApp Business on your smartphone from the App Store(Google Play Store / Apple App Store).

2. open WhatsApp and agree to the terms of use

Enter the desired phone number. A landline number is also possible. In the first small field after the "+" the country code ("49" for Germany) must be entered, this replaces the first 0 of the phone number.

Tap on "Next", check the number and tap on "OK".

WhatsApp will now send an SMS with authentication code by default. If you have entered a landline number, you must select the "Let me call" option.

When setting up with a landline number, the authentication code is communicated by phone call instead of SMS.

‍

6. an SMS is received on the cell phone with the specified phone number, or a call is received on the landline phone, with a 6-digit authentication code that must be entered in the app.

If the code is entered correctly, the profile can then be set up and WhatsApp can be used. Whether you used a cell phone number or a landline number during setup is irrelevant when using WhatsApp.

‍

By the way: You can also use WhatsApp on multiple devices at the same time and use WhatsApp Business with the desktop app or the browser app WhatsApp Web.

‍

Option 2: Clone WhatsApp on Android devices with the "Dual Messenger" function

This option can only be implemented for the standard version for WhatsApp, not for WhatsApp Business. Furthermore, it only works on devices with Android operating system and with a maximum of one additional phone number. The following instructions are tailored to Samsung devices. The procedure is similar for other Android smartphones.

‍

Open the settings
Now select "Advanced functions
Now tap on "Dual Messenger
Flip the switch on "WhatsApp
Confirm that you want to install WhatsApp a second time
Now you have a second WhatsApp app installed on your smartphone and you can set it up with a different phone number

‍

Option 3: Use unlimited WhatsApp Business numbers and devices with WhatsApp API

As can be seen from the previous two options, WhatsApp blocks the use of multiple WhatsApp Business numbers quite successfully. There are tricks to use WhatsApp and WhatsApp Business on the same smartphone at the same time and to use the standard version of WhatsApp with two numbers, but to use WhatsApp Business with more than one number you need the WhatsApp API.

With this so-called application programming interface (API), companies can not only receive and reply to unlimited WhatsApp messages from their customers, but also add any number of phone numbers and devices to the WhatsApp Business account. On top of that, the WhatsApp API is the only way for businesses to use WhatsApp in a 100% GDPR compliant way. Furthermore, fully automated WhatsApp newsletters can be sent to customers via the API, and message templates and chatbots can be used to process customer inquiries highly efficiently.
