The consensus in books and also the answers you've had so far seems to be yes.
I think I'd have to agree with that from my own experience.
What is interesting with Numerology is to play with the variations of your name in every day use.
So check the results for nicknames, married name, middle name initial only etc.
See which works best with how you see yourself.
The name on your birth certificate is your core self as you were in the beginning.
