Pinar (Pınar) is the Turkish word for "spring" — the source of fresh water bubbling from the earth.
Pınar Kür (born 1943) is the Turkish novelist.
Pinar 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 Pinar reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
