As of June 2008, Eve Time Codes (or ETCs) are available exclusively in 60-day increments. Before then, they were also offered in 30-, 50-, 90-, 100- and 120-day increments. Discontinued cards remain valid. Players using ETCs are treated like normal subscribers in every way. Eve Time Codes are available through CCP's online store as well as via online resellers. Cards purchased through resellers are usually delivered through email for immediate use while codes issued through the "Eve Online" store are issued via postal mail or in-game item, and as such ETCs do not violate the EULA and can be bought and sold within the game. There are no distinguishing differences in functionality between digital and hard-copy codes. Both provide the exact amount of specified game time, are entered into the same account section and can be exchanged between players for ISK using a secure exchange system facilitated by a "Timecode Bazaar" forum.
