How to set a WhatsApp username

Setting a WhatsApp username takes about a minute once the option reaches your account. This guide covers the actual steps, what happens at each one, and the sensible way to prepare while you wait.

Before you start

Have your name ready and know that it passes the format rules. Usernames are 3 to 30 characters of lowercase letters, numbers, periods, and underscores, with a few extra restrictions covered in our rules guide. Checking first matters because the app gives you feedback one error at a time, while the username checker shows every rule at once and suggests a fix.

The steps

1. Open WhatsApp and go to Settings, then tap your profile at the top.
2. Look for the Username field below your name and phone number.
3. Type your username. The app validates as you type and tells you if the name is taken.
4. Confirm. The username now appears on your profile.

That is the whole process. The friction is never the steps; it is arriving with a name that is invalid or taken and improvising a worse one under pressure.

What actually changes after you save

People can now start a chat with you by searching your username, without having your phone number. Your number does not become hidden automatically; who can see it depends on your privacy settings, which are worth reviewing at the same time. Our privacy guide walks through the combination that keeps your number out of sight.

If the name you want is taken

You have two honest options: a variant, or a different name used consistently. Generate rule-safe variants with the username generator, and before committing, make sure the variant also works on Instagram and Facebook with the handle checker. A name that only works on WhatsApp splits your identity in half.

While you wait for the rollout

Decide your name now, validate it, and keep it ready. Rollout day then becomes a ten second task. The full waiting checklist is in preparing for the username rollout.
