How to search for someone on Chess.com by username

Open chess.com/member/name to go straight to a player's profile. Chess.com Support also describes two ways to find someone by username: on the web, search the Members page, and in the mobile app, tap the Friends icon and type the username. From there you can send a friend request.

Our check asks Chess.com's public API, so a "Found" answer is reliable for active accounts. Closed accounts may not show. This page does not look up real names.

How to check a Chess.com username

Enter the name you want, using letters, numbers, underscores or dashes, and starting and ending with a letter or number.
We query Chess.com's public data API at api.chess.com/pub/player/<name>. It returns a player record if the name exists; closed accounts may not show there.
Check by hand at chess.com/member/<name>. A "page not found" message suggests nobody uses it.
The rename screen in Settings is the final test, since Chess.com tells you if a name is unavailable.

Chess.com username taken? What you can do

Add a chess word: mia_gambit, mia-endgame, MiaPlaysBlitz.
Use a dash or underscore between words, as long as the name still begins and ends with a letter or number.
If an account impersonates a titled player or you, report the profile or email Chess.com support.
Plan ahead: with a 90-day limit, a temporary name stays with you for three months.

How to change your Chess.com username

Website: open Settings, then Profile, and go to the Details section.
Click Change next to your username, enter the new name and your password, then Save.
Mobile: tap More, then Profile, the three dots, Edit Profile, and tap your username.
If you signed up with Google, Apple or Facebook, you may need to set a password first.

Reserved and restricted names

Usernames must follow Chess.com's community policies, so offensive names and names that pose as titled players, staff or other members can be refused or changed. Names held by closed accounts may also stay unavailable, even when no profile shows.

Tips

You cannot change your username while you are in a live game, so finish your game first.
Your rating, game history and friends all stay with the account after a rename.
Tournament organizers may know you by your old name, so let your club know when you switch.
