A name's Personality Number is calculated from the consonants only, the letters that give a name its outer shape and sound. In Pythagorean numerology, it describes the first impression a child makes: the qualities other people notice before they get to know the person underneath. Where the Expression Number describes a name's full character, the Personality Number is specifically about the surface, the version of someone that shows up in a first meeting, a job interview, or a new classroom.

A Personality Number of 7 gives a reserved, thoughtful first impression. People tend to read this name as belonging to someone intelligent and private, more comfortable observing a room than performing in it. This quiet depth earns respect over time, even though it can initially come across as distant or hard to read.
