Area Calling Code
A telephone numbering plan is a scheme used to distribute international telephone numbers between various continents and cities or among mobile phone providers. Still dial plans are not just the same thing as numbering plans. And the closed numbering plan, it is normal in areas like North America or Australia where local phone numbers are dialed together with appointed length region codes.
A number of countries of the world haven’t yet standardized the size of area dialing codes and local telephone numbers so in these places the open numbering plan is popular. The numbers formed by this plan are dialed differently. You must know which units should be always dialled (these digits form the local phone number) and which may be omitted (calling codes).
Even after the actions of the International Telecommunication Union or ITU to define the norms of numbering plans and international calling codes they still stay different in various places. At first the Union suggested the different countries to have double zero as the international access code. Still the offer was not binding for the state members so only some of them introduced the code, while the rest state members like United States and the members of the North American Numbering Plan stayed on their conditions.

Area codes (the codes that define nations or set of countries) are established by the international numbering plan. In order to control the codes for international calls there is the E.164 standard. It points the common size of the complete number. Still in every country the numbers are set in a different way by local standards. So here are the kinds of regional area codes with:
- The extension officially set by nation standards as it is in the USA (three units) or in Australia and New Zealand (1 unit).
- Uncertain dialing code standards. So in regions like Argentina the code differs between 2 and five, in Japan – between one and five and in Syria or Peru the dialling code contains from one up to 2 digits.
- The norms of big numbers that simply contain the dialing code. They apply it for example in Spain or Norway. In this case the closed numbering plan is applied. Sometimes long-distance area calling codes are applied in regions like Italy, the Netherlands or Switzerland, african countries etc. And generally for this purpose zero is applied.
The dialing code of the region generally enables to charge the people for air time correctly. Generally calling on the numbers within the same area dialling code is really cheaper than calling on the phone numbers with some other dialling code.
But it is generally otherwise in States as there the prices for local calls are controlled by the state itself and the prices often happen to be bigger than for interurban connection.
As it happens that in United States the interval between the callers of one extensive location may be too big, the calls are charged considering the interval despite the area calling code is the same.
Rate centers commonly set the rates, which are set for zones from 0 to six miles, from 6 to 12, and bigger zones. However, it changed with the lack of control of home call services.
Now it’s going popular among the people to use the so-called all-you-can-eat plan (a fixed price of nearly 30 dollars per month as fixed for May 2008 letting call to any city of United States).
In a number of regions cell phone systems use particular area dialing codes. As well they are applied for some special rates, free or premium rates.
There also may be various particular occasions. For example in areas like Egypt calling code mean nothing because the costs remain similar for all the country and in the UK the dialing code is divided into 2 pieces each with its cost.
