How do I block or unblock a contact?
You can prevent a contact from sending you messages by adding their phone number to your Blocked list. To learn more about the effects of blocking a contact, see this article on blocking contacts in WhatsApp.
On iPhone, there are two ways to block a contact:

- Go to WhatsApp > Settings > Account > Privacy > Blocked, then tap the Add New button to add contacts from your address book to your Blocked list.
To unblock a contact, open the Blocked list with the above steps, slide your finger to the left on the contact you wish to unblock, then tap the Unblock button.
