Call of Duty's console and PC games ask for an Activision account before you can play online, while Call of Duty: Mobile lets you play as a Guest and link an account later. You can create one in your phone, tablet, or computer browser without installing a game or owning a console account. Start with browser signup below, or use a supported game's registration screen.

Register when you first launch Call of Duty
Launch Black Ops 7 or current Warzone. Supported editions of Black Ops 6, Modern Warfare III, Modern Warfare II (2022), Vanguard, Black Ops Cold War, and Modern Warfare (2019) also offer in-game registration. Warzone access on PS4 and Xbox One is limited to existing library owners through the end of Black Ops 7 Season 06.

On PC, Warzone requires a verified text-enabled phone number (SMS two-factor authentication) if you don't own a Call of Duty title released within the last two years on that PC platform. In-game registration asks for the number in the account details. If you created your account on an Activision website, you'll verify the number the first time you launch Warzone unless you enabled SMS 2FA during registration.
Keep access to your registered email address for verification and account operations.
After signup, verify your email
Complete email verification when Activision requires it for account operations or access. Two-factor authentication is mandatory for accounts created after August 18, 2026, which are enrolled in email 2FA by default. Activision also automatically enrolls accounts in email 2FA when they verify their email.

Confirm that you can access the displayed email address.
Select Send Verification Email.
Open the verification link delivered to your inbox.

Browser signup alone leaves your new Activision account unlinked to your Call of Duty: Mobile profile.

Tap the Settings gear.
For a Guest account, tap Link in the upper-right corner. For an existing social login, tap the upper-right button showing that linked social account instead.

After the game relaunches, use the Call of Duty icon on its login screen.

Frequently Asked Questions
Can I use Nintendo or Ubisoft credentials to register?
Activision's current support pages document platform sign-in only for accounts that are already linked, not new-account registration with any platform's credentials. Nintendo and Ubisoft are supported for account linking; create your Activision account through browser signup before linking either one.
When did Warzone Mobile and Warzone Caldera close?
Warzone Mobile's servers closed on April 17, 2026. Warzone Caldera's gameplay and online services closed on September 21, 2023.
Can a minor create an Activision account?
Activision's Terms of Use specify age requirements and parental or guardian involvement for minors. Review those requirements before registering.
Should I create a new account if my existing Activision account was hacked?
Start at https://support.activision.com/account-recovery and select MY ACCOUNT WAS HACKED. If you cannot sign in, follow the recovery branch to CREATE A TEMPORARY ACCOUNT using an accessible, verifiable email address. At CONNECTED ACCOUNTS, connect an Xbox, PlayStation, Steam, Battle.net, or Ubisoft account previously linked to the hacked account. Return to recovery and select VERIFY TO CONTINUE. The temporary account becomes inaccessible after recovery, and its progress and purchases cannot transfer.
