Soobin is from the Korean su (수 — excellence, longevity) + bin (빈 — refined, courteous, brilliance). Soobin (Choi Soo-bin, born 2000) — iconic Korean singer; leader of the iconic 4th-generation K-pop boy group TOMORROW X TOGETHER (TXT) (debuted 2019 under Big Hit Music — same agency as BTS); though typically a unisex name, Soobin's leader role has popularized the name; while TXT is a boy group, the name Soobin in Korean is widely used as both masculine and feminine in modern naming. Princess Soobin — modern Korean heritage naming.
Soobin 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 Soobin reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
