Can I use a landline number on WhatsApp Business?

Yes. The WhatsApp Business app accepts a landline number you own. Tap “Call me” to get the verification code by phone call.

• The number must be yours. Mobile and landline (fixed) numbers work.
• VoIP, toll-free, paid premium, universal access (UAN) and “personal numbers” are not supported.
• Landline extension numbers can't be used.
• An account works with one registered phone number. You can't add a second.
• On the API, a landline gets its code by voice call. Meta advises against SMS codes for fixed-line numbers.
