Card PAN Formatter

Paste any Primary Account Number (PAN) and get it grouped the way the issuing scheme prints it on the card — 4-4-4-4 for most 16-digit cards, 4-6-5 for American Express, 4-6-4 for 14-digit Diners, and 4-4-4-4-3 for 19-digit cards. The tool also returns a masked variant (first 6 digits, last 4 digits, bullets in between — the PCI-DSS-safe form used on receipts and dashboards), the detected card brand, the digit count and a Luhn mod-10 verdict. Useful for product engineers building payment dashboards, customer-service agents reading card numbers aloud, and developers formatting saved-card lists.
