Description#

IBAN format masks per country (ISO 3166-1 alpha-2 keys). A = letter, 0 = digit.

Source: official IBAN registry (SWIFT/ISO 13616). Unlike phone numbers, IBAN lengths are FIXED and officially standardised, so these masks are actually reliable, not approximations. IBAN is used in ~70 countries (mostly Europe + parts of the Middle East), hence no US/JP/CN/KR entries.
