New Zealand Country Code

Country codes are numeric “geocodes” (geographical codes) or short alphabetic codes made up to represent nations and subordinate areas on the map, for the purpose of processing data and communications. There are many different systems that have been developed just for this purpose. The most famous system developed is the ISO 3166-1. Country code is also a term which often times refers to global dialing codes. The ISO or International Standards Organization defines names for countries, its territories which are its dependents, and other geographical areas of special interest. The ISO 3166-1 is a division of the ISO 3166, a published standard by the ISO.


“Codes” is the standard’s official name. It is used to represent country names and their sectors. There are 3 sets of Country codes:

ISO 3166-1 (alpha-2) is the country code with 2 letters that is the most frequently used of the 3. It is also the most used by top level domains on the internet for country codes although there are a few exceptions.

ISO 3166-1 (alpha-3) is the country code with 3 letters that allows a better association visually between the name of the country and the codes than does the first one.

ISO 3166-1 (numeric) is the country code with 3 digits that are very similar to those maintained and developed by the UNSD (United Nations Statistics Division).

Its advantage is it is independent of script or any system of writing making it useful even for people or systems which employ scripts which are non-Latin.

Since 1974 when it launched its 1st edition, ISO 3166 has incorporated country codes which are alphabetic.

It was in 1981 that they introduced country codes which were numeric. In 1997, country codes were 1st introduced in the 5th edition of ISO 3166 as ISO 3166-1.


This was when the standard was separated into 3 different parts. As an international standard which is used widely, ISO 3166-1 is in force in other standards and employed by global organizations, to facilitate the exchange of information and goods.

However, ISO 3166 is not the only standard used for country codes.


Other organizations worldwide employ country codes which are in part or totally not compatible with ISO 3166-1. However, there are still some that adhere closely to the codes of ISO 3166-1.

To make an international call to New Zealand’s city of Auckland from overseas, simply dial the local international access code which is usually “00” followed by the NZ country code which is “64” followed by Auckland’s area code which is “9” and then followed by the 7 digit number of the person or institution you are calling.
E.g. 00-64-9-9876543

To make calls inside New Zealand, the national access code is “0” followed by the area code whichever city you are calling. The area code in Northland, Auckland, and the Bay of Islands is “9”, Coromandel, Tauranga (Bay of Plenty), and Hamilton (Waikato) is “7”, Gisborne, Hawkes Bay, Wairarapa, and Palmerston North is “6”, Wellington is “4”, cities in the South Island such as Christchurch, Nelson, Dunedin, Invercargill, and Queenstown is “3”.
