You can change your Battle.net username once every 30 days through your account settings

Your Battle.net username is the name that appears to other players in Overwatch, Diablo, World of Warcraft, and other Blizzard games. To change it, log into your Battle.net account on the Blizzard website, go to Account Settings, select the Profile tab, and click the Edit button next to your username. Type your new name, confirm the change, and it takes effect when ready in all your Blizzard games.

The process takes about two minutes. You do not need to restart your games or log out and back in — the change is live as soon you confirm it. However, Blizzard enforces a 30-day waiting period between username changes, so you cannot change it again until 30 days have passed since your last change.

Key Takeaways

  • Log into Battle.net on the Blizzard website, navigate to Account Settings, and select the Profile tab to find your username change option.
  • Your new username appears when ready in all Blizzard games and to other players without requiring a game restart.
  • You can change your username once every 30 days, and Blizzard counts this limit from the date of your last change, not from the calendar month.
  • Usernames must be between 3 and 12 characters, contain only letters, numbers, and hyphens, and cannot start or end with a hyphen.
  • If your desired username is taken, you will see an error message and must choose a different name before you can proceed.

Step-by-step process to change your username

Start by going to the Battle.net website and logging in with your email and password. Once you are logged in, look for your account name or profile icon in the top right corner of the page and click it to open the dropdown menu.

From the dropdown, select Account Settings. On the Account Settings page, click the Profile tab on the left side. You will see your current username displayed with an Edit button next to it. Click that button to open the username change form.

Type your new username into the text field. As you type, Battle.net will tell you whether the name is available or already taken. If it is taken, you will see a red X and must choose a different name. Once you see a green checkmark indicating the name is available, click the Save Changes button to confirm.

Your new username is now active across all Blizzard games. You do not need to log out or restart anything — other players will see your new name when ready in-game.

Username rules and what names are not allowed

Battle.net usernames must be between 3 and 12 characters long. You can use letters (A–Z, case does not matter), numbers (0–9), and hyphens (-), but the name cannot start or end with a hyphen. For example, "Player-123" is allowed, but "-Player123" and "Player123-" are not.

Blizzard does not allow usernames that contain profanity, slurs, or references to real people's names. The system also blocks names that impersonate Blizzard staff or famous players, and names that are primarily numbers with no letters. If you try to use a name that violates these rules, you will see an error message explaining why it was rejected.

Your username is different from your Battle.net account name (your email address). Changing your username does not change your email or password, and other players cannot see your email address — they only see the username you display.

What happens if you hit the 30-day waiting period

If you try to change your username before 30 days have passed since your last change, the Edit button will be grayed out and you will see a message telling you when you can change it again. The 30-day timer starts from the exact date and time you made your previous change, not from the start of the next calendar month.

For example, if you changed your username on March 15 at 3 p.m., you cannot change it again until April 14 at 3 p.m. There is no way to bypass this waiting period, and Blizzard support cannot override it even if you contact them.

Changing your username does not affect your game progress or friends list

Your games, achievements, rank, cosmetics, and all other progress remain exactly the same when you change your username. Your friends will still see you in their friends list, and you will still see them in yours. The only thing that changes is the name displayed next to your character and in chat.

If you were in a guild or clan before the change, you remain a member after the change. Your guild leader and other members will see your new username, but your rank and permissions stay the same.

If your desired username is taken

When you type a username that is already in use, Battle.net shows a red X and tells you the name is unavailable. You must choose a different name — there is no waiting list or way to reserve a username that someone else currently has.

If you want a specific name badly, you can try variations: adding numbers to the end, using hyphens between words, or swapping similar letters. For example, if "Shadowblade" is taken, you might try "Shadowblade1", "Shadow-blade", or "Shadowblad3". Keep in mind that the name must still follow the 3–12 character rule and cannot start or end with a hyphen.

Frequently Asked Questions

Can I change my username if I have an active ban or suspension?

No. If your account is suspended or banned, you cannot change your username until the suspension or ban is lifted. Once your account is active again, you can change it normally and the 30-day timer resets from that point.

Does changing my username affect my Blizzard Authenticator or two-factor authentication?

No. Your security settings, Authenticator, and two-factor authentication remain active and unchanged. You log in with your email and password the same way you did before.

What if I want to change my username back to what it was before?

You can change it back, but you must wait 30 days from your most recent change. If you changed from "OldName" to "NewName" today, you cannot change back to "OldName" until 30 days from now. At that point, "OldName" must still be available — if someone else has claimed it, you cannot use it.

Can I change my username on console or mobile?

No. You must change your username through the Battle.net website on a computer. You cannot do it through the Blizzard Launcher, the mobile app, or any in-game menu.

If I change my username, will my old name become available for someone else to use?

Yes. Once you change your username, your old name goes back into the pool of available usernames and someone else can claim it. If you want to keep that name reserved, do not change your username.
