Call of Duty MW3 Codes & How to Redeem

If a Call of Duty MW3 code fails, use these checks to narrow down the cause:

• Check the code status. Compare the code with the active list and expired history on this page. An expiry date may not have been announced; an error alone does not tell us why a code failed.
• Check the spelling. The recorded rules allow different capitalization. Copy "XBLX3-HN7X7-7NAH7" exactly as listed and remove any extra spaces.
• Already redeemed. The recorded rules allow one redemption per account. A code you have already claimed cannot be used again on that account.
• Check the redemption steps. Follow the instructions above, including any tutorial or progression requirement, and use the listed redemption menu.
• Still having trouble? Note the exact error message, platform, server, and whether you have used the code before. Include those details when reporting the problem so we can investigate.
