Shahrazad is from the Persian shahr (شهر — city) + zād (زاد — born) — "city-born" or alternatively Chehrāzād ("of noble lineage"). Princess Shahrazad — Persian-Arabic heritage naming.
Shahrazad 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 Shahrazad reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
