How short or long can my trainer name be?

I’m trying to think of my new trainer name but I don’t get any chance to check if the username is available before trying it.

What I’m wondering is what the minimum and maximum characters are for your trainer name?

  • What is the maximum gym level?
  • What is the minimum RAM required for Pokemon GO?
  • How is (52000 / 50000) gym prestige possible?
  • Why do the Pokemon always have three pawprints?
  • Can other players see me on their map?
  • How much xp/prestige do you gain at a gym by training?
  • How many evolutions can be done in 30 minutes
  • Does Pokémon Go recognize gym prestige higher than 52k?
  • How do I pick a team?
  • How can I put my pokemon in an allied gym in Pokemon Go?
  • How can I play Pokémon GO without Internet?
  • What do the hearts around a Pokestop mean?

    After some brief experimentation, I’ve discovered that your new proposed trainer name must be between 4-15 characters. It can only contain letters and numbers (no special characters or spaces).

    In addition, if you try to change your trainer name to one that is already taken, the game will flash an error message saying That name isn't available, so it’s okay to try a bunch of different trainer names to find one that is available.
