How do I choose a number for the WhatsApp Business API?

Which number is suitable for WhatsApp Business API and which is not? Is it possible to use a landline or toll-free number? How do I connect the company's existing number to WhatsApp Business API, and what will it take?

This article has collected answers to popular questions, requirements, and recommendations for choosing a number when connecting to WhatsApp Business API. The material will be constantly updated depending on changes in the principles and rules of WhatsApp.

Be very careful about choosing a number. The number connected to WhatsApp Business API cannot be used in the regular WhatsApp and WhatsApp Business App; if the number has already been linked to the WhatsApp Business API, then the procedure for excluding it from the WhatsApp Business API database may take more than one month. You can use our WhatsApp Shared Inbox chat or a visual bot constructor to work with a number without the WhatsApp application.

Which number is suitable for connecting WhatsApp Business API?

To begin with, we will analyze the "ideal" version of the number for connecting the WhatsApp Business API, and below, we will give exceptions to the rules and more controversial situations:

- The number must include the country and region cod; short numbers are unsuitable. For the same reason, toll-free numbers "8-800" are not correct;

- The number should not be connected to WhatsApp and WhatsApp Business App. Before joining WhatsApp Business API, the WhatsApp account must be deleted as follows;

- The number can be stationary; whelming the number, it will be important not to miss the verification call \ SMS by disabling the interactive voice response system (IVR) and setting up a virtual PBX for this;

- The number should not be banned in WhatsApp applications. Also, connecting the phone numbers of Iran, Syria, the DPRK, Crimea, and several other countries and territorial entities will not be possible.

How will the number be connected to the WhatsApp Business API if the organization uses it in WhatsApp applications?

WhatsApp Application Number Database – WhatsApp Business App and WhatsApp Business API are separate databases. If the number is in the WhatsApp application database, it cannot be used in the API and vice versa. You will find detailed instructions on transferring a number from WhatsApp applications to WhatsApp Business API here.

During the emigration process, all incoming messages will be saved on WhatsApp servers and will come to you after the transition is completed. It is worth downloading the previous correspondence history since it will not be held during emigration.

Is a landline number suitable?

A landline number can be connected to WhatsApp Business API. At the same time, the number must be able to receive a verification call or SMS, for this you will need to disable the interactive voice response system (IVR) and install a virtual PBX to capture incoming SMS.

Verification of the number will also occur at the end of the business verification stage and with double authentication of the number, if you enable such a service in the Meta Business Manager personal account.

And if I already cooperate with the API provider, can I go to you, while keeping the number?

Starting from July 2021, this became possible. For more information, the procedure for switching from one API provider to another is described here.

Can I connect several numbers?

Yes, it is also possible. Write to us how many numbers you would like to connect, and we will offer you a discount on a comprehensive connection. Learn more about the price and terms of connection.

Is it possible to connect several WhatsApp Business API accounts to one number?

Meta is categorically against this.

Are you sure you can't use toll-free numbers 8-800?

We would say that we do not recommend using 8-800 numbers. In exceptional cases (we don't know why), such numbers are approved by Meta. We cannot name the exact reasons for such decisions, nor can we guarantee the result if you decide to connect the 8-800 number to the WhatsApp Business API.
