• Your business should own the number
• There should be a country and area code
• Must be able to receive voice calls or SMS
• The number should not be previously associated with any other WhatsApp Business Platform

The list will show the numbers you configured. You can then choose one of the available numbers to be reconfigured with the channel and click Save.
Keep in mind, before you select the number to be reconfigured to your channel, the Business Name Status must show as Approved, the phone number Connection Status can be Pending or Disconnected, and the phone number Verification Status must be Verified as highlighted in the following screenshot.
If you have not configured any number(s) to your Facebook Business Manager Account, an error message will pop up as shown below. Click the WhatsApp Business Account button which will redirect you to your Facebook Business Manager Account to add a number.
Reasons you might not be able to select a number from the available list:

- Business name rejected: The business name you registered was rejected by WhatsApp. In this case, you have to restart the process and try again to get it approved by WhatsApp. for more details, read the WhatsApp Commerce Policy.

- OTP verification pending: Click Verify to complete the verification process and select a method to receive the OTP (one-time password) either through an SMS or a voice call. Once you receive the six-digit code, enter it and click Verify OTP. If there is a delay in receiving the OTP, please click Resend Code.
- Business name verification pending: The business name you registered is awaiting WhatsApp approval.
- Number configured in a different channel: The number you are selecting is connected to one of your other channels.
