International Country Codes

These are codes that are short that may be composed of 2 or 3 alphabets to represent a country that can be used for communicating or processing data. They are actually there to put order. Today, there have been various systems that were formulated for this function. Usually, the ISO (International Organization for Standardization) 3166 Maintenance Agency is responsible for publishing and revising these codes. It was ISO that developed these 2 alpha and 3 alpha codes for the different countries in the world, including dependent and independent states and areas with special status or jurisdiction.




Additionally, there are other country codes like the IOC or the International Olympic Committee, which used also 3 alpha codes when they help sports events. Same thing goes with the North Atlantic Treaty Organization or NATO. They also use their own 2 alpha codes.

International Zip Codes

This is the system of postal codes that is being used to speed up the sending of mails all over the world. ZIP stands for Zone Improvement Plan. Usually, the basic format for ZIP codes is 5 digit numerals. They serve the purpose of directing mails to a specific location with the use of these codes, other than just following the city.

And right now to even make it easier to sort mails and get to their destination faster, zip codes are now translated into Postnet. These are the short and long barcodes that you usually see printed on the mail. Sorting becomes easy with the use of automated machines that can read these barcodes.

The first number of the ZIP code actually represents a certain group of state, then the second and third may represent a region or a city. The last numbers usually defines the main town. Knowing what each number stands is important in grouping the mailing addresses.

International Call Country Codes

These are the numbers that were assigned to each country or region or even mobile phones. They are typically being dialed first before dialing the local number. The access code for national calling is 0 while for international, the access code is 00. It was ITU Telecommunication Standardization Sector but formerly CCITT was the first to develop this list of telephone country codes for the different countries allover the world.

The way this list was organized is by creating a zone for each international region.
  • Zone 1 - United States, Canada, Bermuda and other Caribbean nations
  • Zone 2 - for Africa and other Atlantic Islands
  • Zone 3 - Europe
  • Zone 4 - Europe
  • Zone 5 - Mexico, South America, Caribbean, and Central America
  • Zone 6 - Oceania and Southeast Asia
  • Zone 7 - Russia, former Soviet Union
  • Zone 8 - East Asia and other special services
  • Zone 9 - South, Central, West Asia and Middle East
Knowing these international country codes would never be put into waste since they are very important in communication and processing data worldwide.
