The in-game Account Creation screen requires you to enter a Display Name, a valid email address, and a password. You'll also need to set your region and decide whether or not you'd like to receive marketing emails before confirming your account. You can also create an account online.

After accepting the Call of Duty Account Terms of Service and Privacy Policy, your account registration will complete, and your Account Summary will display.

Note that your Account Summary includes your Activision ID, which is the name you'll appear as in game.

If you already have an Activision account, you can log in with the account's email address and password. After logging in, your Account Summary will display.

Note that your Account Summary includes your Activision ID, which is the name you'll appear as in game.

After signing up or logging in, you'll see your Activision ID, also referred to as your Display Name. Activision IDs include a hash mark followed by a series of numbers (ex: DisplayName#1234567). This number is unique to your Activision account and allows players with the same Gamertag, PSN ID, BattleTag, or SteamID to keep their names while differentiating them in game. The numbers also make account creation easier, eliminating the need to see if a name is available.

You can change your Activision ID/Display Name with a Username change token. You'll receive a new Username change token every six months, and you can carry up to two tokens at any given time.
