Korean Last Names

Korean Surname Checker is a free lookup tool that identifies whether any name is a Korean surname. Type in a name — in any spelling, including Lee, Yi, or Rhee — and it instantly returns the Hangul, Hanja (Chinese character), meaning, population count, and national rank, pulled from the 2015 South Korean census. It covers all 191 recognized Korean surnames and can also flag Chinese or Vietnamese surnames that share the same characters, helping users tell them apart.
