Jinni is the Korean stage name from jin (truth, jewel) + ni (you). debut hits O.O (2022) + Dice (2022). From JYP's Loud survival show 2021.
Jinni does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Jinni reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
