Controls When Messaging Businesses
You are in control when you message with a business on WhatsApp. It’s up to you whether or not you share your number with a business, and you can block a business at any time. WhatsApp will not give your number to a business, and our policies prohibit businesses from contacting you on WhatsApp without first receiving your approval to do so.
When you receive a message from a business for the first time, we will provide you with the option to block or report the business in case you don’t want to hear from them again. And at any point during a conversation with a business, you can block or report it from its profile.
When you block a business account, you can also tell us why, such as because you no longer need to message that business or you didn’t sign up to receive messages from them. We may use these insights to provide feedback to businesses so they can improve their chats with customers. We may also use this block and report information to take action on an account or limit the messages it can send.
