Rica is a modern Filipino feminine diminutive — possibly from the Spanish rica (rich) or the Greek Erika. Rica Peralejo (born 1981) is a Filipino actress, singer, and television host — among the Filipino entertainment figures of the late 1990s and 2000s alongside Jolina Magdangal and Heart Evangelista. films include Booba (2001) and Liberated (2003).
Rica 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 Rica reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
