WhatsApp has launched verified business accounts, which let users talk to companies through its messaging app.

Business accounts which are verified by WhatsApp will receive a green badge next to their contact name, which means WhatsApp has confirmed the phone number belongs to the business.

“WhatsApp will also let you know when you start talking to a business via yellow messages inside a chat. There is no way to delete these messages from the chat,” it said.

“If you already have a business’s phone number saved, the name you will see is the name you have saved in your address book.”

If users want to stop a business from contacting them, the contact can be blocked.

WhatsApp business verification is currently limited to a small number of businesses participating in a pilot programme.
