Ways to add more WhatsApp phone numbers

There are various options for adding more WhatsApp phone numbers. All options have their own pros and cons. It doesn't matter whether the number added is a mobile number, a landline number or possibly the number of the second SIM card in the mobile phone.

‍

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

With this option, you cannot be reached via multiple numbers via WhatsApp Business, but you can still use a WhatsApp Business account on the same device on which your private WhatsApp account is already installed — with a different phone number.

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

‍

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

2nd Open WhatsApp and agree to the terms of use

3rd Enter the desired phone number. Also a Landline number is possible. In the first small field, the country code (“49" for Germany) must be entered after the “+”, which replaces the first 0 of the phone number.

4th Tap Next, check the number, and tap OK

5th WhatsApp now sends an SMS with an authentication code by default. If you have entered a landline number, you must select the “Let me call” option

When set up with a landline number, the authentication code is sent by phone call instead of via SMS

6th An SMS is received on the mobile phone with the specified phone number, or a call on the landline telephone, with a 6-digit authentication code, which must be entered in the app.

7. If the code has been entered correctly, the profile can then be set up and WhatsApp can be used. Whether you used a mobile number or a landline number when setting it up doesn't matter when using WhatsApp.

‍

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

‍

Option 2: Clone WhatsApp with the “Dual Messenger” feature on Android devices

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

‍

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

Option 3: Use an unlimited number of WhatsApp business numbers and devices with the WhatsApp API

As can be seen from the previous two options, Is WhatsApp blocking use Quite successful from several WhatsApp business numbers. While 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, to use WhatsApp Business with more than one phone number, you need the WhatsApp API.
