Where can I locate my CD Key?
Civilization V requires a CD key when purchased via retail, this key is printed on the back of the games manual in the following possible formats:
- AAAAA-BBBBB-CCCCC-DDDDD-EEEEE
- AAAAA-BBBBB-CCCCC
The key may contain numbers and letters, also ensure that when entering the key you include the dashes and enter the letters in upper case.
Note: If you have purchased the game via Steam no CD key is necessary as the game will automatically appear in your Games list once purchased.
