Life Path Numbers in numerology are also often called soul, destiny, or spiritual path numbers. They are derived from adding together the individual digits of a birthdate until you get a single digit number, except for master numbers (11, 22, and 33), which are considered special and not reduced further. Therefore, there are a total of 9 possible single-digit life path numbers (1 through 9), and three master numbers (11, 22, and 33).
