There is no place online to legally obtain free "Animal Jam" member codes. The only legitimate ways to obtain "Animal Jam" memberships are to pay the monthly subscription fee or to participate in giveaways from its parent company, the National Geographic Society.
Sites that claim to provide free "Animal Jam" codes may contain viruses or other malware. Even sites that do not harm the user's computer admit that they hack the "Animal Jam" site to illegally obtain codes, in-game currency and other items.
Game players obtain free gems and items safely and legitimately from issues of "National Geographic" magazine or from the "Animal Jam" blog. These codes do not provide membership time; instead, they provide gems, diamonds, animals, items and special events. Some items provided by free codes only work for paid members.
