Redeem on the website, not in the console store

Activision’s support page sends you to callofduty.com/redeem. Sign in, type the code, pick a linked platform if asked, then confirm. Restart the game if it was already open.

Steps that match the support article

The article’s order is sign in, open the redeem page, enter the code, fill any extra field or platform choice, press redeem, and read the confirmation. The logged-in form also lives at profile.callofduty.com/promotions/redeemCode/. I did not find a PlayStation Store or Microsoft Store path for these strings. Do not hunt through the console wallet.

Current strings are listed on the codes page. This page is only the procedure.

FAQ

Can I redeem on PS5 without a browser?

The support article does not describe an on-console keyboard path. Use the website.

The reward is missing in game.

Restart the client. The article calls that out when the game was already running.
