Can I use a landline number to register WhatsApp for my business?
You may use any number, including landlines, mobile numbers, or toll-free numbers. You must, however, be able to receive an OTP or answer a verification phone call from WhatsApp on the number you provide. It should also be a number with no previous WhatsApp registrations associated with it.
If you’re unsure, the Clickatell support team is able to confirm whether your number is valid for WhatsApp Business use before registration.
