Subscriber trunk dialling (STD), also known as subscriber toll dialing, is a telephone numbering plan feature and telecommunications technology in the United Kingdom and various Commonwealth countries for the dialling of trunk calls by telephone subscribers without the assistance of switchboard operators.
North Ockendon is the easternmost settlement of Greater London, England, and part of the London Borough of Havering. It is 18 miles (29 km) east-northeast of Central London and consists of a dispersed settlement within the Metropolitan Green Belt. It was historically an ancient parish in the county of Essex, which was abolished for civil purposes in 1936. North Ockendon is the only inhabited area in Greater London outside the M25 London Orbital Motorway. North Ockendon is north of South Ockendon, in Thurrock, Essex.
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.
All-figure dialling was a telephone numbering plan introduced in the United Kingdom starting in 1966 that replaced the traditional system of using initial letters of telephone exchange names as the first part of a telephone number. The change affected subscriber numbers in the cities of Birmingham, Edinburgh, Glasgow, Liverpool, London and Manchester which used the Director telephone system.
The RM postcode area, also known as the Romford postcode area, is a group of twenty postcode districts in south-east England, within nine post towns. These cover parts of eastern Greater London and south-west Essex. Inward mail for the area is sorted, along with mail for the E and IG postcode areas, at the Romford Mail Centre.
The Big Number Change addressed various issues with the telephone dialling plan in the United Kingdom, during the late 1990s and early 2000s, when the country was running short of new telephone numbers.
A telephone exchange name or central office name was a distinguishing and memorable name assigned to a central office. It identified the switching system to which a telephone was connected, and facilitated the connection of telephone calls between switching systems in different localities.
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.
020 is the national dialling code for London in the United Kingdom. All subscriber numbers within the area code consist of eight digits and it has capacity for approaching 100 million telephone numbers. The code is used at 170 telephone exchanges in and around Greater London as part of the largest linked numbering scheme in the United Kingdom. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling London from abroad.
The New Zealand telephone numbering plan describes the allocation of telephone numbers in New Zealand and the Pitcairn Islands.
The London Telephone Region was an administrative unit of Post Office Telephones in Britain formed in 1936. It comprised all of the London Telephone Area plus the charging groups adjacent, for example: the Romford Charge Group, comprising Hornchurch, Ingrebourne, Purfleet, Rainham, Romford, South Ockendon, Stapleford and Upminster telephone exchange areas.
0191 is the UK telephone dialling code used by Newcastle upon Tyne, Durham, Sunderland and other nearby areas in the north east of England.
PhONEday was a change to telephone numbering in the United Kingdom on Sunday 16 April 1995. A shortage of unique telephone numbers in the old dialling system meant that it was becoming increasingly difficult in certain areas of the country to assign unique numbers to new subscribers. To counteract this, dialling codes starting with 0 were changed to start with 01. In Bristol, Leeds, Leicester, Nottingham and Sheffield, the existing area codes, which were 5 digits in length, were instead entirely replaced with new codes comprising 4 digits, to increase the amount of possible numbers by a factor of ten. The changes made possible the ability to provision new numbers in each of these five cities. It also had the effect of assigning all geographic landline telephone numbers into one range of numbers starting with 01, allowing for further changes to be made at the Big Number Change in 2000. A £16m advertising campaign, and an eight-month parallel period during which both old and new codes were active, preceded the change. PhONEday followed a change made in May 1990, when the old London area code 01 was 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 the Easter Sunday bank holiday in 1995.
0114 is the national dialling code for Sheffield in the United Kingdom. The area it serves includes almost all of the City of Sheffield and some adjacent areas. When STD codes were first introduced, Sheffield was assigned the mnemonic 0SH2, later changing to the corresponding numbers upon the introduction of All-Figure Dialling in the area. Instead of the expected 01742 code, Sheffield's area code changed to the current 0114 code on 16 April 1995, along with 4 other cities in England, as part of PhONEday. All subscriber numbers within the area code consist of seven digits. The code is used at several telephone exchanges as part of a linked numbering scheme. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling Sheffield from abroad.
The 01633 telephone area code covers the city of Newport and surrounding areas in the United Kingdom. Before PhONEday the area code was 0633, which was originally dialled as "0NE3" where the "NE" were formed from the first two letters of NEwport on the telephone dial. In common with all other British area codes the initial '0' is a trunk prefix that is dropped when dialling from abroad.
Telephone numbers in the United Kingdom have a flexible structure that reflects their historical demands, starting from many independent companies through a nationalised near-monopoly, to a system that supports many different services, including cellular phones, which were not envisaged when the system was first built. Numbers evolved in a piecemeal fashion, with numbers initially allocated on an exchange-by-exchange basis for calls connected by manual operators. Subscriber numbers reflected demand in each area, with single digit telephone numbers in very rural areas and longer numbers in cities.
01527 is the national dialling code for Redditch in the United Kingdom. Before PhONEday the area code was 0527. The mnemonic for 0527 corresponds with LA 7 where LA could have been taken from the letters L and A in Lapworth, a small village in Warwickshire close to Redditch but not served by the 0527 dialling code. The original dialling code for Redditch was 0739, with the mnemonic RE 9 where RE are taken from the letters R and E in Redditch.
01932 is the national dialling code for Weybridge in the United Kingdom. Before PhONEday, the area code was 0932. The mnemonic for 0932 corresponds with WE 2, where "WE" is taken from the letters W and E in Weybridge.
