World wide postcodes?

Question

does every dwelling on earth have a postcode?

Answer 1

No, actually quite a few countries don't have postal codes.

"In February 2005, 117 of the 190 countries members of the Universal

Postal Union had post code systems. Examples of countries that do not

are: Ireland (although a national postal code system will be

introduced in 2008 [1]), Hong Kong, and Panama."

List according to UPS of countries that don't have zip or postal codes.

Does Ireland use postal codes? What form do Irish postal codes take?

"In Ireland, only Dublin City has postal codes, and they are really

postal districts. You will notice that all of Dublin City centre

establishments are in "Dublin 1" or "Dublin 2", etc. Outside the city,

it is simply County Dublin. The postal code system for Dublin is

relatively simple. Odd numbers are addresses on the North side of the

River Liffey. Even numbers are on the south side (except for parts of

Dublin 8, which encompasses part of the Phoenix Park). Dublin 1 is the

North City Centre. Dublin 2 is the South City Centre."
