Your Activision ID is the unique account identifier you need to play Blizzard games

Your Activision ID is a username you create when you set up a Battle.net account — the login system for games like World of Warcraft, Overwatch 2, Diablo IV, and Call of Duty. It looks like a name followed by a number, such as "ShadowNinja#1847". You need this ID to log into games, add friends, and join multiplayer sessions.

If you already have a Battle.net account, your Activision ID is visible in your account settings right now. If you do not have an account yet, you create your Activision ID during the signup process. Either way, the process takes less than five minutes.

Key Takeaways

  • Your Activision ID is the username and number combination you use to log into Battle.net and all Blizzard games.
  • You can find your existing Activision ID by logging into Battle.net on your computer or phone and checking your account settings.
  • If you do not have an Activision ID yet, you create one for free when you sign up for a Battle.net account at battle.net.
  • Your Activision ID is different from your email address — it is the display name other players see when you play together.
  • You can change your Activision ID once per year, though the number portion stays the same unless you pay for a name change.

Find your Activision ID if you already have a Battle.net account

Open a web browser and go to battle.net. Click the "Sign In" button in the top right corner and enter the email address and password you use for your Battle.net account. Once you are logged in, look for your account name in the top right corner of the page — this is your Activision ID.

If you want to see your full ID with the number, click on your account name in the top right and select "Account Settings". On the left side of the page, you will see a section labeled "Battle Tag" or "Account Name" — this shows your complete Activision ID, including the number at the end.

On a phone or tablet, the steps are the same. Open battle.net in your browser, sign in with your email and password, and tap your account name to view your full ID. You can also find this information in the settings menu of any Blizzard game you have installed — look for "Account" or "Profile" in the game's main menu.

Create an Activision ID if you do not have a Battle.net account

Go to battle.net and click "Create Account" in the top right corner. You will be asked for an email address, password, and your date of birth. Enter these details and click "Create Account".

On the next screen, you will be asked to choose your Activision ID — the username that will appear in games. Type in a name you want to use. Battle.net will automatically add a number to the end (like #1234) to make sure no two players have the same ID. You can see what your full ID will look like before you confirm it. Once you are happy with it, click "Create" and your account is ready to use.

The entire process takes about two minutes. After you create your account, you can download and install any Blizzard game, then log in with your email and password. Your Activision ID will appear automatically when you start playing.

What to do if you forget your Activision ID

If you cannot remember your Activision ID but you know the email address tied to your account, go to battle.net and click "Sign In". Enter your email address and password. Once you are logged in, your Activision ID appears in the top right corner of the page and in your account settings.

If you cannot remember your password either, click "Forgot your password?" on the Battle.net sign-in page. Battle.net will send a password reset link to your email. Click the link, create a new password, and then sign in. Your Activision ID will be visible in your account once you are logged in.

Change your Activision ID if you want a different name

Log into battle.net and go to "Account Settings". Click on "Profile" or "Battle Tag" depending on what your version shows. You will see an option to change your Activision ID. Click it and type in the new name you want. Battle.net will show you the full ID with the number attached.

You can change your Activision ID once per year for free. If you want to change it again before a year has passed, you will need to pay a fee — the exact cost varies by region. The number portion of your ID (the part after the #) stays the same even if you change the name part, unless you pay extra for a full name change.

Where your Activision ID appears and how other players see it

Your Activision ID is visible to other players in every Blizzard game you play. When you join a multiplayer match, send a friend request, or chat in a game, other players see your full Activision ID including the number. This is how they find you to add you as a friend or send you messages.

Your Activision ID is also what appears on leaderboards, in guild rosters, and in match history. It is the name tied to your account across all Blizzard games — if you play World of Warcraft, Overwatch 2, and Diablo IV on the same account, your Activision ID is the same in all three games.

Frequently Asked Questions

Is my Activision ID the same as my email address?

No. Your email address is what you use to log into Battle.net, but your Activision ID is a separate username that other players see. You choose your Activision ID when you create your account or change it later in your account settings.

Can I have the same Activision ID as someone else?

No. Battle.net automatically adds a number to the end of your chosen name to make sure every ID is unique. Two players can have the same name part (like "Shadow") but different numbers (like "Shadow#1847" and "Shadow#3092").

What if I want to remove the number from my Activision ID?

You cannot remove the number — it is a required part of how Battle.net identifies accounts. The number is added automatically when you create your ID and stays the same even if you change the name part. The number is what makes your ID unique.

Do I need a different Activision ID for each Blizzard game?

No. One Activision ID works across all Blizzard games on your account. If you own World of Warcraft, Overwatch 2, and Diablo IV on the same Battle.net account, you use the same ID to play all of them.

Can I see other players' Activision IDs?

Yes. You can see the Activision ID of any player you encounter in a game, on a leaderboard, or in a friend list. This is how you find people to add as friends or send messages to.
