It doesn't need a certain level, you just have to either use a thunder, fire, or water stone or increase it's happiness A LOT and then level it up at night or day. all these ways create different forms of Eevee whom I will name.
Thunder = Jolteon.
Water = Vaporeon.
Fire = Flareon.
Happiness by day = Espeon.
Happiness by night = Umbreon.
Moss rock = Lefeon.
Ice rock = Glaceon.
i have Pokemon soul-silver and i evolved my evee using a thunderstone
In Pokemon Diamond, Pearl, and Platinum, if you want to evolve your Evee to a Leafeon you go to the Eterna Forest You will have to level up your Evee there and once it levels up by one level, it evolves to a Leafeon. If you want a Glaceon, you level up eevee on route 217. To get a Flareon, you give Evee a Fire stone. For Vaporeon, you give it a Water stone. And for a Jolteon, you need a Thunder stone.
Level up an Eevee with full happiness at nighttime (after 6pm)
