A CD Key is the serial number or product code that activates a product. It is usually a combination of letters and numbers and normally found on a sticker inside the game's case or printed on the game's quick reference card.
The purchased CD Key is used to register and activate the relevant game. Depending on the product, we provide this in the form of a photograph of the code from the game's case or the code in a text format.
