There are three master numbers in numerology - 11, 22 and 33. Predicting a master number properly is very important as they have very deep and powerful meanings. The interpretation could be good or bad, and the numbers mostly used for right guidance in life. Typically, only single digit numbers from 1 to 9 are used for numerology predictions. However, when the sum total of numbers equates to any of the three master numbers, it doesn't reduce further.

Master number 22 - It is the 'Master Builder' and indicates fiery ambitions and tremendous success. However, it requires very careful reading that only an expert can do.
Master number 33 - Relates to life path, personality or expression
