Araceli is from the Spanish Araceli — from Latin Ara Coeli — compound of Latin ara (altar) + caeli (of heaven). Araceli is one of the Spanish feminine names — central to traditional Spanish Catholic + Latin American Marian heritage. Spanish feminine name reflecting Catholic Marian heritage.
Araceli 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 Araceli reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
