Pokémon Go Eevee evolution: How to evolve Eevee into Umbreon, Espeon, Vaporeon, Jolteon and Flareon with new names
In the classic Pokémon games, Eevee can evolve into different typing varieties based on the use of special items, its happiness level, moves it has available and even the time of day.
With the addition of Candy in Pokémon Go, the way you evolve Pokémon is much simpler, and as such, you cannot use the tried-and-tested method of using one of three elemental stones to turn Eevee into Flareon, Jolteon and Vaporeon. (Some are better than others depending on the situation - find out which you should get first with our Best Pokémon in Pokémon Go page, and our Pokémon Go Type Chart for their relative strengths and weaknesses.)
Once you have caught enough Eevees to evolve one - our pages on finding Pokemon by location, finding which Pokemon hatch from which eggs and locating Pokémon nests near you can help - a neat trick discovered by fans of the game on Reddit will get you the evolution you need.
Worth checking, too, is our page on the best Pokémon in Pokémon Go, seeing as Umbreon and Espeon in particular are pretty strong new additions with Gen 2!
How to evolve Eevee into evolutions Umbreon, Espeon, Vaporeon, Flareon and Jolteon
If you choose to evolve Eevee without any meddling - by feeding it 25 Eevee candy - then it'll turn to one of the below five types at random. However, users have discovered a trick that allows you to target any of Espeon, Umbreon, Flareon, Jolteon or Vaporeon, by renaming it in one of the following ways:
Note the trick works only once per evolution type, so make sure you choose Eevees with the best CP values before you evolve them into the type you want.
Newcomers Umbreon and Espeon are also believed to have a second evolution method, and that's through the Buddy System, according to Reddit. By walking either one 10km, and then evolving it during night (Umbreon) or day (Espeon) it'll turn into the desired evolution.
Since the naming trick only works once per evolution type, this appears to be a useful way to get a second Espeon or Umbreon with some reliability.
What you need to know about Eevee Evolution names in Pokémon Go
Why Sakura, Tamao, Sparky, Rainer and Pyro? The original three are the names of the Eevee brothers from the Pokémon television show, who meet with Ash and the gang in episode 40 to show off their respective Eevee evolutions, with Sakura and Tamao appearing later on in the series.
Once you have called your Eevee into one of the above names, you should quit and reload the app to double check the name change has taken place, which is important considering the servers can lean to be on the unreliable side.
Once you've double checked the new name is indeed in place, then evolve the Eevee as you would any other Pokémon by feeding it Candy, and it should take the form of your chosen type.

Note that while plenty of users have had success with this method - and that it's been confirmed by developer Niantic itself at this year's San Diego Comic Con - there are a handful of cases where it hasn't worked every time. Some say the trick will only work on the first time you evolve the creature, while others might have caught fowl of server issues not renaming their successfully first time, so be sure to check before you try.
