All pre-orders through a participating retailer come with a code to register for the Call of Duty: Vanguard Beta*. In most cases, the Call of Duty: Vanguard Beta code will be printed on the retail receipt or sent to you via email on an online receipt. If you didn't receive a Beta code or can't locate it, please contact your retailer.
If you pre-order Call of Duty: Vanguard through the PlayStation Store, Xbox Store, or Battle.net, you don't need a code. You're automatically registered to participate in the Call of Duty: Vanguard Beta* on PlayStation 5, Xbox Series X|S, PlayStation 4, Xbox One, or PC.
