How to change your username and AstralTag

Your public identifier is an AstralTag: username#tag, for example Marty_McFly#3. Friends add you with that string.

The parts

Part	Meaning	Rules
Username	Technical handle	1–32 characters: a–z, A–Z, 0–9, _. Case-insensitive
Numeric tag	1–4 digits	From 1 to 9999
Display name	How you appear in chat	Up to 32 characters, optional. Falls back to username

Change your AstralTag

1. Open User Settings (gear at the bottom left).
2. Go to Profile.
3. Click Change AstralTag.
4. Enter the new username and, if available, a tag. Click Continue.

The account must be claimed. Otherwise the button is disabled — see How to create an account and sign in.

Tags and Plutonium

Without Plutonium the system picks the tag. If the new name+tag is taken, Astral rerolls a free discriminator for you.

With Plutonium you can pick an available tag such as #0001 or #1337. If it is taken, choose another.
