Carli is a 21st-century American feminine of Carl — Old Germanic karl (free man). Her hat-trick in the first 16 minutes of the 2015 FIFA Women's World Cup Final against Japan — including a goal from the halfway line — is among the most iconic single performances in soccer history; she became the first player ever (any gender) to score a hat-trick in a World Cup final. National Soccer Hall of Fame (2024).
Carli 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 Carli reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
