Description#

Postal-code format masks per country (ISO 3166-1 alpha-2 keys). A = letter, 0 = digit; a | declares length alternates picked by input length.

Note (like phone numbers): not every country has a strictly fixed format (Ireland's Eircode is highly irregular), so treat these as UI hints, not hard validators. Countries with no postal-code system (HK, AE, ...) are intentionally omitted - do not apply a zip: mask there.
