- First names — Every name from the birth certificate (middle names included) and any name taken later.
- Surnames — The current one and every earlier one: birth (maiden) name, married name, name after divorce or adoption.
- Spelling — Exactly as in the documents, with every accent and special character. No nicknames or short forms.
- Date of birth — The full date of birth: day, month and year.
Every letter carries a numeric value, so a missing name changes the result — including the Expression Number, the Soul Number and the Outer Expression Number. Not sure whether a name counts? Add it — fuller data means a more accurate result.
