How to get an Official business account
A business account on WhatsApp can either be listed as an "Official business account" or a regular "Business account". A business can't request or pay to turn a "Business account" into an "Official business account".
At this time, only certain business accounts are listed as "Official business account". Listing a business as an "Official business account" is based on a variety of factors, such as whether the brand is notable.
Any account using the WhatsApp Business app will automatically be listed as a "Business account". Businesses can help customers learn more about their company by filling out their business info, including their business website, address and hours.
