A WhatsApp Business Account (WABA) needs a valid, dedicated business phone number. This document describes business phone number requirements and features, how to register phone numbers, and how to manage registered phone numbers.
If you are working with a Solution Partner they will manage your business phone number for you.
To be eligible for registration, business phone numbers must be:
Registered numbers can still be used for everyday purposes, such as calling and text messages.
Numbers already in use with the WhatsApp Messenger app or WhatsApp Business app cannot be registered unless they are deleted first. See our How to delete your account help center article if you wish to delete your number.
Banned WhatsApp numbers cannot be registered unless they are unbanned first. Contact support if your account is banned and you wish to appeal.
A business phone number display name is the name that appears in WhatsApp Manager. Having a business phone number with an approved display name is one requirement for your business to become an Official Business Account.
You can set a display name when you add a business phone number in the App Dashboard > WhatsApp > API Setup panel, or in the WhatsApp Manager > Account tools > Phone numbers panel, if you haven't reached your phone number limit.
If you submit your business for business verification and it becomes verified, we will either:
In each case, we will notify you by
phone_number_name_update webhook and Meta Business Suite notification.
If approved, we will set your business phone number's
If rejected, we will set your business phone number's
DECLINED. We recommend that you re-review our display name guidelines, edit your display name accordingly, and file an appeal via Developer Support or Enterprise Developer Support.
If asked to message more, we don't have enough API usage data to determine if your number warrants a display name. Continue using the API, monitor phone number and message quality and take appropriate actions to improve your quality scores, and we will automatically re-review your display name at a future date.
You can register a business phone number using the App Dashboard when completing the steps in our Get Started document.
If you didn't register a number when completing the steps in the Get Started document, return to the App Dashboard, go to the WhatsApp > API Setup panel. Scroll down to Step 5: Add a phone number, click the Add phone number button, and complete the flow.
As part of the registration process we will send a voice or SMS message containing a verification code to your phone number to verify that you are the phone number owner.
Note that you can also register a number using the WhatsApp Manager. See our How to connect your phone number to your WhatsApp Business account help center article to learn how.
If you are registering a 1-800 number, see Registering 1-800 and Toll Free Numbers for additional information.
To delete a registered business phone number:
Businesses may want to register a 1-800 or other toll free number on the platform. These numbers are usually behind an Interactive Voice Response (IVR) system, however, which a WhatsApp registration call cannot navigate. Phone numbers behind an IVR system can be registered, but must be able to accept calls from international numbers and be able to redirect our SMS message or voice call to a real person.
To register a phone number that is behind an IVR system:
Phone numbers behind an IVR system that are unable to receive registration calls are not supported.
Business phone numbers can only be registered for use with one API at a time: Cloud API or On-Premises API.
Business accounts are initially limited to 2 registered business phone numbers, but this limit can be increased to up to 20.
If your business has been verified and your business phone number has an approved display name (or if you have two business phone numbers and they both have approved display names) we will determine if your API usage warrants a phone number limit increase.
If we determine an increase is warranted, we will automatically increase your limit and notify you by
business_capability_update webhook and Meta Business Suite notification of your new limit.
If we determine that an increase is not warranted, we will keep your limit at 2. If more than a week has passed since your business has been verified and your limit is still 2, ensure that you are monitoring phone number and message quality and take appropriate actions to improve your quality scores. After improving your quality scores, if we determine that your business warrants an increase, we will automatically increase your limit and notify you by webhook and Meta Business Suite notification of the new limit.

You can migrate phone numbers from one WABA to another, as well as migrate a number from On-Premises API to Cloud API (or vice-versa).
To reset or disable two-step verification on your business phone number using WhatsApp Manager, first access its two-step verification settings:
To disable two-step verification, click the Turn off two-step verification. An email with a link will be sent to the email address associated with your Meta business account. Use the link to disable two-step verification. Once disabled, you can re-enable it by setting a new PIN. You can also set a new PIN using our APIs:
To change your PIN, click the Change PIN button and complete the flow. You must supply your current PIN to change before you can change it.
