Geographic numbers are nine digits long, including the area code, but not including the leading zero. Consequently, densely populated areas have shorter area codes, while less populated areas have longer area codes. For example:

  • 6 xxxx xxxx (Osaka)
  • 75 xxx xxxx (Kyoto)
  • 742 xx xxxx (Nara)
  • 4992 x xxxx (Niijima island, Tokyo pref.)
  • 82486 xxxx (Takano, Hiroshima pref.)

Area codes increase from north to south; Sapporo in Hokkaidō (the northernmost prefecture) has 11, and Setouchi's 99-73 is far to the south in Kagoshima. When the telephone system was devised, Okinawa was still under U.S. occupation, so when it was returned to Japan in 1972, its telephone numbers were squeezed between Miyazaki (98x) and Kagoshima (99x) and begin with 988, 989, and 980.

During the 1990s, when plans were being drawn up to amalgamate mid-sized cities and towns into larger municipalities, telephone numbering systems were merged in advance. For example,

  • 7442 x xxxx Kashihara (Nara prefecture)
  • 7444 x xxxx Sakurai
  • 74452 xxxx Takatori
  • 74454 xxxx Asuka etc.

became:

  • 744 2x xxxx Kashihara
  • 744 4x xxxx Sakurai
  • 744 52 xxxx Takatori
  • 744 54 xxxx Asuka etc.

Many of these towns have in fact refused to merge, leaving callers with more digits to dial when making local calls. This is partially balanced by not having to dial an area code for the neighboring city.

A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls instead of incurring charges to the originating telephone subscriber. For the calling party, a call to a toll-free number from a landline is free of charge.

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 administrative regions of the public switched telephone network (PSTN) and they are also present in private telephone networks. For public number systems, geographic location plays a role in the sequence of numbers assigned to each telephone subscriber.

Telephone numbers in Singapore, also known as the National Numbering Plan, are regulated by the Info-communications Media Development Authority (IMDA). Due to the small geographical size of Singapore, there are no area or trunk codes; all numbers belong to one numbering area, and thus come in the same 8-digit format. Numbers are categorised based on the first digit, thus providing ten possible categories, of which six are currently in use and the remaining four reserved for future usage.

PhONEday

PhONEday was a change to the telephone dialing plan in the United Kingdom on 16 April 1995. It changed geographic area codes and some telephone numbers. In most areas a "1" was added to the dialling code. In Bristol, Leeds, Leicester, Nottingham and Sheffield the area codes were replaced with new codes and the subscriber numbers gained an extra digit. The PhONEday changes also made provision for new ranges of subscriber numbers in those five cities. A £16m advertising campaign, and an eight-month period of parallel running during which old and new codes were active, preceded the change. PhONEday followed a change made in May 1990 when the old London area code 01 had been released from use, permitting all United Kingdom geographic numbers to begin with this prefix. Originally planned in 1991 to take place in 1994, in 1992 the change was postponed until 1995.
