Card number

Use test-card numbers only (Stripe, sandbox, dev data). Never paste a real production card.

BIN ranges are a curated subset (~35 ranges covering the major global networks). Luhn passing doesn't mean the card is real or active - it only confirms the check digit is mathematically valid.
