Verified WhatsApp Business Account (with green badge)
If your WhatsApp Business API account is an official business account, the display name will be visible in the chat list, chat screens and contacts view instead of the phone number. There will be a green checkmark beside the displayed name in the contacts view.
Business Account (Not a official business account - No Green badge)
If your WhatsApp account is a business API account, the display name will only be shown in the contacts view in smaller text; all other views will show the phone number. You can help customers learn more about your company by filling out your business info, including business website, address, and hours.
