My Numerology Number

The premise that you have only one numerology number is incorrect.

Your name number is the number 7 and your birth date number is the number 9. Those are the most important.

In your numerology chart, the name number is referred to as the destiny number and the birth date number is referred to as the life path number.

There are other important numbers. The core numbers article describes the ones at the top of the list.
