Starting January 1, 2012, fixed lines will be allowed to dial directly to other provinces/countries, but still using open dialing plan. To dial to other province, dial area code+phone number (0xx-xxxxxx), and to dial to other countries, dial 00+country code+phone number.
Before 2012, dialing to other provinces is 101, then wait for operator, the same thing as to other countries, but to other countries is 100. Before 2012, mobile phones are already allowed to dial to other provinces/countries directly.
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country.
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks.
In the United Kingdom, telephone numbers are administered by the Office of Communications (Ofcom). For this purpose, Ofcom established a telephone numbering plan, known as the National Telephone Numbering Plan, which is the system for assigning telephone numbers to subscriber stations.
International direct dialing (IDD) or international subscriber dialling (ISD) is placing an international telephone call, dialed directly by a telephone subscriber, rather than by a telephone operator. Subscriber dialing of international calls typically requires an international call prefix to be dialed before the country code.
In Argentina, area codes are two, three, or four digits long. Local customer numbers are six to eight digits long. The total number of digits is ten, for example, phone number (11) 1234-5678 for Buenos Aires is made up of a 2-digit area code number and an 8-digit subscriber's number, while (383) 123-4567 would be an example of a Catamarca number.
Numbers on the Irish telephone numbering plan are regulated and assigned to operators by ComReg.
A trunk prefix is a digit sequence to be dialled before a telephone number to initiate a telephone call for the purpose of selecting an appropriate telecommunications circuit by which the call is to be routed.
Widespread UK telephone code misconceptions, in particular brought on by the Big Number Change in 2000, have been reported by regulator Ofcom since publication of a report it commissioned in 2004.
The dialling plan for mobile networks and new landline operators is closed; all subscriber numbers must be dialled in full. For landline numbers starting with 02, the dialling plan used to be open; the trunk digit and area code could be omitted if the caller was in the same area code as the callee. However, starting May 3, 2008, all landline numbers must be dialled in full.
The Brazilian telephone numbering plan uses a two-digit area code plus eight-digit local phone numbers for landlines and nine digits for mobile lines. Public utility services use short phone numbers, always starting with 1.
International telephone calls are those made between different countries. These telephone calls are processed by international gateway exchanges (switches). Charges for these calls were high initially but declined greatly during the 20th century due to advances in technology liberalization. Originally they were placed via long-distance operators. The calls were transmitted by cable, communications satellite, radio, and more recently, fiber optics and Voice over Internet Protocol (VoIP). International direct dialling was introduced in the 1970s, so calls can be dialed by country code without an operator.
Telephone numbers in Italy are managed by the Autorità per le Garanzie nelle Comunicazioni (AGCOM), a national regulatory authority for the communication industry located in Rome.
Telephone numbers in Pakistan are ten digits long. Landline numbers and mobile numbers have different structures. Geographically fixed landline are prefixed by an area code which varies in length depending on the significance of the place. Mobile numbers are prefixed (03) followed by a two-digit code indicating the telephone operator. The international country code for Pakistan is +92.

A telephone number in Belgium is a sequence of nine or ten digits dialed on a telephone to make a call on the Belgian telephone network. Belgium is under a full number dialing plan, meaning that the full national number must be dialed for all calls, while it retains the trunk code, '0', for all national dialling.
National conventions for writing telephone numbers vary by country. The International Telecommunication Union (ITU) publishes a recommendation entitled Notation for national and international telephone numbers, e-mail addresses and Web addresses. Recommendation E.123 specifies the format of telephone numbers assigned to telephones and similar communication endpoints in national telephone numbering plans.
North Macedonia's telephone numbering plan is the system used for assigning telephone numbers in North Macedonia. It is regulated by the Agency for Electronic Communications (AEK), which holds responsibility for telecommunications.
