WhatsApp was built as a simple, secure and reliable way to message other people. Messaging is by its nature private and our Terms of Service are designed to help keep our platform and our users safe. People have asked us for help understanding how to use WhatsApp responsibly, so we've developed these guidelines to help ensure users have a good experience on WhatsApp. All users of WhatsApp, including government entities, political parties, and candidates for office, should follow these rules when using WhatsApp. For more information on how WhatsApp prevents abuse of automated and bulk messaging, read this white paper.

Best Practices for Use of WhatsApp

• Private communication by design: Users should manage their own accounts for one-on-one chats and small group conversations.
• Gain people's permission: Messages should only be sent to people who have contacted you first or have requested you contact them via WhatsApp. It's best to give people your phone number so they can message you first. If people provide their phone number, message them in ways they would expect. For example, explain who you are, and how you got their phone number.
• Respect people's choices: If a user asks you to stop messaging them, you should remove the user from your address book and refrain from contacting them again. You should get permission from people before you add them to a group. If you add someone to a group and they remove themselves, please honor that decision.
• Use Group controls: We've created an admin only message setting for WhatsApp groups. If you're an admin, you can decide if all participants or only group admins can send messages within the group. Using this feature can help cut down unwanted messages in groups.
• Think twice before forwarding: We have affixed a label to all forwarded messages to encourage people to think before sharing.

Practices to Avoid

• Unwanted, automated, or bulk messages: Don't try to bulk message, auto-message or auto-dial using WhatsApp. WhatsApp uses both machine learning technology and reports from users to detect and ban accounts sending unwanted messages. This includes the systematic contacting of users in ways they may not want. Also, don't create accounts or groups in unauthorized or automated ways, or use modified versions of WhatsApp.
• Use contact lists that are not yours: Never share phone numbers without people's consent or use data obtained from illicit sources (by buying lists of phone numbers for example) to message users on WhatsApp or add them to groups.
• Over-use broadcast lists: Messages sent using a broadcast list will only be received when users have added your phone number to their contact list. That said, the frequent use of broadcast messages may lead people to report your messages. We block accounts that are reported multiple times.
• Violate our Terms of Service: As a reminder, the Terms of Service prohibit, amongst other things, publishing falsehoods and engaging in illegal, threatening, intimidating, hateful, and racially or ethnically offensive behavior. The Terms of Service define your contractual relationship with WhatsApp, and the Terms of Service take precedence to the extent there is any conflict with this document.
