Do you need a phone number for WhatsApp Business?
Yes. The app needs a mobile number that receives a code; the WhatsApp Business API needs any number that can receive one code once — a landline, a virtual number or a toll-free number all work — and it must not already be on WhatsApp.

Yes. The WhatsApp Business app needs a mobile number on a phone, and it receives the verification code by SMS or call. The WhatsApp Business API needs a number that can receive a code once, at registration — a landline with voice verification, a virtual number, a toll-free number — and never needs a SIM again after that. In both cases the number must not already be registered on WhatsApp; a number moving from the app to the API is deleted from the app first.
Businesses usually keep the number customers already know and move it to the API rather than starting a new one.
