I don't know how to claim these codes I have.
Most codes are country specific and must match your Blizzard account's country before you can claim them. Country-specific codes cannot be transferred from one country to another. If you're having trouble claiming a code, be sure the code was entered correctly on the Code Redemption page. Try using all CAPS to enter the code.
If the issue persists, contact Customer Support help.Note: Item or pet codes distributed prior to BlizzCon 2009 and all World of Warcraft Trading Card Game item codes must be redeemed through the World of Warcraft Promotion Code Retrieval page.
