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 (which corresponded to 0742 on a rotary dial), 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 (Leeds; 0113, Nottingham; 0115, Leicester; 0116 and Bristol; 0117), 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.
Before 1965, Sheffield had 5-digit telephone numbers, with the first digit indicating the exchange area of the telephone line. Sheffield's 6-digit numbers were implemented by prefixing the original 5-digit numbers with a duplicate of the first digit (seen below), other than the 2xxxx numbers which were prefixed by 7 (as seen by the last example). This grouped telephone numbers centrally in the 1 to 9 range with a larger "buffer" at the extremes.
Switching to 6-digit numbers produced 90,000 available numbers for each exchange group, providing another 450,000 available numbers after combining both phases, producing a potential 500,000 numbers in Sheffield.
Until the 1980s, Stocksbridge, Oughtibridge, and some other areas had 4-digit numbers. Within Stocksbridge and Oughtibridge people dialed only 4-digit numbers, while from Sheffield people dialed prefix 88 for Stocksbridge and prefix 86 for Oughtibridge. From Oughtibridge, people dialed 88xxxx for Stocksbridge and 9xxxxxx for Sheffield. This led to some confusion, leading people to often dial wrong numbers. During the 1980s these local areas were unified into 6-digit Sheffield numbers so that from anywhere in the Sheffield code area, 88xxxx dialed a Stocksbridge number, even from within Stocksbridge. Once the 8-prefix was merged into the full local number this released 8xxxxx numbers.
Transitioning to 7-digit numbers in 1995 involved prefixing each 6-digit number with a 2. Immediately after the 1995 change, the corresponding 22x-xxxx numbers became available for allocation, followed by the 20x-xxxx and 21x-xxxx ranges, since the corresponding 0742 0xxxxx and 1xxxxx wouldn't have been issued as local numbers weren't permitted to start with a 1 or a 0. The 0114 code allows for a potential maximum of 7,990,000 local numbers to be issued, assuming the use of the entire valid range from (0114) 200-0000 to (0114) 998-9999 country-wide.
