International Dialling Code
No commentsA phone numbering plan is a scheme used to arrange international telephone numbers among various countries and regions and among mobile phone operators. Anyway dial plans are not absolutely the same as numbering plans. Or there is a closed numbering plan applied in regions like Canada or Australia. For closed plan it is necessary that there are local phone numbers completed with appointed length territory codes.
An open numbering plan supposes that telephone numbers and dialing codes can be different subject to the land and region they belong to. The numbering plan works in lots of countries today. The numbers defined by the open plan are dialed differently. You must know which units should be anyway dialled (these digits form the subscriber’s number) and which can be omitted (area calling codes).
Even after the suggestions of the International Telecommunication Union or ITU to arrange the norms of numbering plans and international dialing codes they still stay different in different places. ITU desided to have 00 as a general international access code for all the participating countries. Several nations have answered yes to the suggestion and assigned the code, still as changing the combination was not compulsory for the nations in a number of them like the USA the calling codes remained as they used to be.

According to the international numbering plan country dialling codes are defined. Country code stands for a nation or a number of countries. Specially to control the codes for international calls there is the E.164 system. It defines the general extension of the full number. It happens so that in every country the phone numbers are set differently by local systems. Well, district area codes are divided into those that are with:
- Defined norms of the code that consists of a number of digits like three in United States or 1 in New Zealand.
- Indefinite dialing code norms. So in regions like Austria the calling code differs between 2 and 5, on japanese isles – between one and five and in Peru and Syria the calling code includes from one to 2 figures.
- Special standards supposing that the subscriber’s number has the dialing code in its structure, like in Spain or Norway. These are the pecularities of the closed numbering plan. As for some areas, they have 0 as a trunk dialing code. It’s popular in lands like Italy and Belgium, the Netherlands or Switzerland, South Africa or some locations within the NANP.
The calling code of the region generally enables to charge the subscriber for calls the right way. It’s mainly a bit cheaper to call on the numbers with local or neighboring calling code then on those that have calling codes of other countries.
But it is mainly otherwise in the USA as there the rates for local calls are controlled by the state itself and the costs sometimes happen to be bigger than for trunk calls.
But it may turn so that one area dialing code serves for a big territory. The calls then are to be evaluated depending on the distance of the call.
The valuation centers commonly assign prices for territory zones measured in pieces of nearly six, 12 or more miles. However, as the control of home phone services was finished that all changed.
Now it’s becoming popular between the subscribers to take the so-called all-you-can-eat plan (an assigned price of about $30 monthly as fixed for spring 2008 letting call to any place of United States).
There may be extraordinary area dialing codes. They are used mainly for cell phone systems in the regions where they are covered by the caller or for free, premium accounts.
There also can be various particular circumstances. For example in countries like Egypt dialing code evaluate nothing as the costs stay similar for all the country and in the UK the dialing code is divided into two parts every one with its cost.
