Have you ever wondered how people send a message on WhatsApp that looks completely empty? Since WhatsApp doesn’t allow users to send a message without any content, many people assume it’s impossible. In reality, there’s a simple workaround that uses an invisible Unicode character.
This guide explains how blank WhatsApp messages work, how to send them using invisible characters, why people use them, and what limitations you should know. Everything is explained in simple language so anyone can follow along.
A blank WhatsApp message is a message that appears empty to the recipient. Instead of containing visible letters, numbers, or emojis, it contains a special Unicode character that has no visible appearance.

Important: A blank message is not truly empty. It contains an invisible Unicode character.
