CDKEY refers to the serial code required for software registration. Most commercial software requires a serial code (or CDKEY code) to be installed, and these serial codes are generally marked on the product packaging or manual. The installation serial number (SN, serial number) and CDKEY code form a specific product registration code after the software is installed. Users can also use this set of registration codes to register with the software manufacturer to obtain various technical support services in the future. Simply put, cdkey is the software registration code, the password or serial number for installing the software on the CD. In layman's terms, it is a registration code or serial number, which is used to maintain the author's copyright.

8CDKey is the only professional website in China that specializes in selling CDKeys for overseas games and European and American games. Its main business is selling European and American game CDKeys, game peripheral products (monthly cards, CDs, technical documents) , VPN, account, gold coins, etc.) are all available. It is also one of the earliest virtual value-added service providers in China.

The products sold on this site are scanned images of the actual products, not the actual products. However, CDKey alone cannot complete account registration. You also need a monthly card or credit card to activate CDKey. Because game companies charge a certain monthly game fee every month. Activating with a monthly card or credit card is the payment method for players' monthly fees. Therefore CDKey has only one function: register an account. The monthly card or credit card has two functions: one is used to activate CDKey, and the other is used to renew the existing game account. It should be noted that CDKey generally comes with 30 days of game time (for example, if a player uses a monthly card to activate CDKey, then the account will be the time of the monthly card plus the time of CDKey). There is a very special kind in CDKey, which is the expansion pack. The expansion pack is based on the original game, in-depth development, adding plot, adding game tasks, making appropriate corrections and upgrades to the original game. It is generally based on the original game, adding new characters, plots and scenes, focusing on the plot. An expansion rather than a change in software version, the core of the original game is still used. It is a supplement to the game. The content that can be supplemented includes: upgrades and modifications to the game program, new storylines, new maps, equipped weapons, etc. The reason why it is called an expansion pack rather than a sequel is because the expansion pack does not transcend the original framework of the game as a whole. It is just an icing on the cake, so it is called an expansion pack. Most European and American games will continue to add new maps to the game over time. Of course, game companies will not let players enter these maps for free, so players need to purchase CDKs that can access these maps to add to their existing accounts. . This type of CDKey can be divided into two types in function, one can only be used to access existing accounts, and the other can be used to access existing accounts and register new accounts.
