Can You Use 1-800 and Toll-Free Numbers for WhatsApp Business API?

It is challenging to use 1-800 and toll-free numbers for WhatsApp Business API because they are typically behind an Interactive Voice Response (IVR) system. However, WhatsApp can provide one to two phone numbers for registration calls. You can use this information to create an allow list, which enables you to redirect the registration call to an employee or mailbox where the registration code will be captured.

If creating an exception in your IVR tree is possible, add the phone number to your WhatsApp business account and open a Direct Support ticket to request the registration call phone numbers and state the phone number you are attempting to register in the ticket.
