Ireland ZIP Codes

Ireland uses an “Eircode” system, which is a seven-character alphanumeric format like A99 AAAA, featuring an alternating letter-digit-digit pattern followed by a space and four letters. This system is alphanumeric, unlike the purely numeric US ZIP codes. Ireland has 139 postal codes covering 3,380 regions and 51,780 towns.
