Numerology Compatibility and Ashtakoot Are Different Counts
Romantic compatibility in numerology reduces birth dates to digits and compares those digits. Romantic compatibility in Jyotish matching compares two Moon nakshatras through Ashtakoot, eight kootas totaling 36, and then still has to read both 7th houses. A shared digit is not a koota score.

What the digit method actually does
Add the digits of a birth date and reduce, keeping 11, 22, or 33 if you follow master-number practice. Do the same for the other person. Compare the results with whatever table that numerology book prefers. The operation never asks for a birth time, so it never produces a lagna, a 7th lord, or a Navamsa. Two people can share a life-path number and have 7th lords in dusthanas. Two people can have clashing digits and a clean D9. The number is a property of the calendar date. The marriage house is a property of the clock and the city.
What Ashtakoot asks instead
Varna 1, vashya 2, tara 3, yoni 4, graha maitri 5, gana 6, bhakoot 7, nadi 8. All of it hangs on the Moon's nakshatra and, for bhakoot and graha maitri, on the Moon's sign and its lord. A couple can score well here and still be badly matched in the 7th house, which is why the koota total is a screen, not a wedding. Nadi alone is 8 points. No life-path comparison contains an 8-point nadi. If someone offers you a single compatibility percentage blended from both systems, they have added a digit to a nakshatra and called it one science.
A workable order
If you like the number, keep it as a symbol the two of you share or do not share. For the marriage question, cast both lagnas, name both 7th lords, open both Navamsas, and only then look at Ashtakoot if a family match requires it. Venus remains the karaka. A numerology table that ranks Venus-ruled numbers as romantic is still not Venus in the chart. The graha is in a sign, in a house, in a dasha. The digit is not.
Frequently asked questions
Can life path numbers replace kundli matching?
They cannot. They ignore the birth time. Without the time there is no 7th house and no Navamsa, which are the marriage readings.
Does a matching digit repair nadi dosha?
Nadi dosha is a shared lunar nadi, worth 8 points. A digit has no nakshatra. It cannot score, clear, or replace that koota.
Where does Venus fit?
Venus is the marriage karaka in the horoscope. Its sign and house come from the ephemeris. A numerology 'Venus number' is a different system and does not locate Venus.
