Warzone is filled with fancy cosmetics that you can kit out your operator and loadouts with, so find out how you can claim calling cards and weapon charms for free using these codes.

The vast majority of Warzone’s cosmetics are locked behind the game’s battle pass, but there are times where Activision gives out free items.

These range from weapon blueprints, calling cards, charms, and emblems. While the latest Operator skins and popular weapon camos may cost real money, there are a number of items that don’t cost anything at all. 

Whether you’re looking to spice up your loadout with various weapon charms or just want some calling cards, then you’ll want to utilize the latest codes. Not only will they help give you a unique look, but they can all be claimed without spending a dime. 

Active Warzone codes

There are currently no active codes for Warzone as of March 5, 2025. There have been no new ones added since the launch of Black Ops 6 in late 2024, but that doesn’t mean there won’t be in the future, especially with Verdansk making its return.

Things have been more active on the multiplayer side, though, as players can get free Black Ops 6 codes through Monster Energy. These items can then be used in Warzone after the integration.

How to redeem codes

Claiming free calling cards and weapon charms in Warzone is incredibly easy and only takes a few seconds. In order to claim these free cosmetics, you’ll need to do the following: 

1. Head over to the official Call of Duty website
2. Log in with your account details 
3. Copy and paste the code you wish to use and hit ‘Redeem Code’
4. Load up Warzone
5. Check for whatever cosmetic or bonus item you claimed in the appropriate section

Activision

If done correctly, you should see all your claimed rewards ready to go. Finally, simply head over to your loadout, customization options, or operator and equip any items you wish to use before dropping into the action.
