As a sidenote: the mention of Ireland not having postal codes led me to the wiki article: http://en.wikipedia.org/wiki/Postal_addresses_in_the_Republic_of_Ireland http://en.wikipedia.org/wiki/Postal_addresses_in_the_Republi... which goes into detail: >"The introduction of a National Postcode System, known as "Eircode", is planned to take place in Summer 2015." >"An Post did not introduce automated sorting machines until the 1990s. By then, the optical character recognition (OCR) systems were advanced enough to read whole addresses, as opposed to just postcodes, thereby allowing An Post to skip a generation. Consequently, mail to addresses in the rest of the state does not require any digits after the address."
