This discord regex supports both the new and the old version of discord names.

Old: NAME#[0001-9999]

  • Between 2 and 32 characters.
  • Any character except # is allowed

New: NAME

  • Between 2 and 32 characters.
  • Latin, lowercase letters are allowed (a-z)
  • All numbers are allowed. (0-9)
  • Underscores are allowed. (_)
  • Periods are allowed. (.)
    • You cannot have two consecutive period characters.
