Charli is the modern English feminine of Charles — from the Old Germanic karl (free man). Vroom Vroom EP (2016) is considered to hyperpop. A top-1000 US baby name since 2020.
Charli 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 Charli reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
