Ananya comes from the Sanskrit ananya (अनन्या), composed of an (not) and anya (other) — literally "not other," meaning unique, unparalleled, without equal. In classical Sanskrit literature it appears as an epithet, often used to describe devotion that cannot be diverted elsewhere.
Ananya is one of the most popular girl names in modern India, particularly in the Hindi-speaking north and in the South Asian diaspora abroad. It has begun appearing in U.S. and U.K.
Ananya 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 Ananya reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
