If you obtain an Eevee you can evolve it into the following Pokemon; Espeon, Umbreon, Vaporeon, Flareon, Jolteon , Glaceon, Leafeon , or you can keep it as it is but to evolve an Eevee you have to have a certain item to evolve it! To evolve an Eevee you must get the item you need and graduate from the guild, after you graduate you can go to Luminous Spring!( Where you evolve) And keep your item in storage or in you bag. When you see your Eevee name on the option to evolve you click on it and it will say "Do you want to use (item) to evolve Eevee?" click yes and your Eevee will evolve! You can obtain them all on Wonder Mail S! Or job list... Hope This Helps! PS: These codes cannot be used on the European version
