Izinombolo zocingo zase-UK zisebenza kanjani?
Uhlelo lwezinombolo zocingo lwase-UK lunendlela exakile futhi eyinkimbinkimbi eyazalwa ngenxa yezinguquko eziningi ezingokomlando nokungajwayelekile. Ngokuyisisekelo cishe zonke izinombolo ziqala ngo-0 lapho zishaywa e-UK. I-0 yokuqala iyashiywa uma ubiza usuka phesheya bese kufakwa isiqalo esithi "+44" esikhundleni sayo. Inombolo yesibili ibonisa uhlobo lwenombolo. Izinombolo ezibizwa ngokuthi ezendawo (ezihlotshaniswa nekhodi yendawo) ziqala ngo-01 noma ngo-02. Izinombolo eziqala ngo-03 azihlotshaniswa nanoma iyiphi ikhodi yendawo kodwa zikhokhiswa ngamanani afanayo nezinombolo eziqala ngo-01 noma ngo-02. Izinombolo zomakhalekhukhwini zihlala ziqala ngo-07. Izinombolo eziqala ngo-09 ziyizinombolo ezinenani eliphakeme ezibiza imali eningi ngokuhlinzeka ngezinsizakalo ezengeziwe. Izinombolo eziqala ngo-080 azikhokhelwa. Amanye amanani aqala ngo-08 akhokhiswa ngamanani akhethekile kodwa hhayi amanani aphezulu kakhulu ezinombolo zika-09.  Izinombolo ezikhethekile ezingaqali ngo-0 zihlanganisa u-999 no-112 ezimweni eziphuthumayo, u-101 ezindabeni ezingewona ezokuphepha eziphuthumayo, u-111 wokuxhumana ne-National Health Service ezimweni ezingewona eziphuthumayo kanye nezinsizakalo zokubuza izinkomba eziqala ngo-118.  Umlando wamakhodi we-UK (ukuqala ngo-01 no-02) uqala ngezikhathi lapho izikhungo zocingo ngazinye zazinekhodi yazo eyodwa, ezimbili noma ezintathu ze-Subscriber Trunk Dialing (STD) (isb. B yeBirmingham noma i-AY6 ye-Aylesbury). ngo-1966 amakhodi e-STD aguqulwa aba izinombolo kusetshenziswa amaphethini ezinombolo ekudayeleni kwezingcingo (lapho i-2 = ABC, i-3 = DEF njll) ngakho iBirmingham yaba yi-021, i-Aylesbury yaba yi-0296. I-01 kwakuyikhodi eyabelwe iLondon. Amakhodi endawo ayenezinhlamvu eziphakathi kuka-2 no-5 kuhlanganise no-zero wokuqala. Ukulandela ikhodi yendawo, kwanezelwa inombolo yendawo enezinombolo eziphakathi kuka-3 no-7 emgqeni ngamunye ukuze inombolo ephelele ibe nezinombolo ezingu-9 noma ezingu-10 ubude. Abashayela ngaphakathi kwekhodi yendawo efanayo babengashayela eminye imigqa enekhodi efanayo ngokumane bashayele inombolo yendawo ngaphandle kwekhodi yendawo. Ngo-1968 amakhodi ezindawo aqala ngo-00 asuswa ukuze kukhululwe u-00 ukuze asetshenziswe kwezinye izinto.  Ngawo-1980, izici eziningana zabangela ukuba izindawo ezithile, ikakhulukazi iLondon, ziphelelwe amakhodi. Kwaqalwa izinyathelo ezihlukahlukene kuhlanganise, ngo-1990, ukuhlukaniswa kweLondon ku-071 (e-London yangaphakathi) no-081 (e-London engaphandle).  Ama-80 nama-90s nawo abona ukwethulwa kancane kancane kwezinombolo "ezingezona ezomhlaba" ngokwesibonelo izinombolo zamahhala ezingama-0800 kanye namaphethini amaningi wezinsizakalo zeselula ezivelayo. Izinsizakalo ze-premium rate nazo zaqaliswa ngokusebenzisa i-0898.  Ngo-1995 kulokho okubizwa ngokuthi "phONEday" kwanezelwa u-1 oholayo ngemva kuka-zero. Izinombolo zaseLondon zaba u-0171 noma u-0181, iBirmingham 0121, i-Aylesbury 01296 njll.  Lokhu kwasungula iphethini esiyibona namuhla evumela amanye amakhodi ezindawo ukuba athuthele kumakhodi "02" eminyakeni embalwa ezayo. Ngaphezu kwalokho, amadolobha amakhulu anikezwa amakhodi amasha aqala ngo-011, isibonelo, u-0113 eLeeds, u-0117 eBristol.  Ngo-2000 "ushintsho olukhulu lwezinombolo" lwabona amakhodi aseLondon eshintsha futhi = 0171 waba ngu-020 7 no-0181 waba ngu-020 8 okuvumela ukuthi kukhishwe izinombolo ezintsha zaseLondon eziqala ngo-020 3 no-020 4. Amanye amadolobha athola amakhodi wesitayela "02" yiSouthampton / Portsmouth 023, Coventry 024 neCardiff 029. Kwafakwa ikhodi ehlanganisiwe engu-028 eNyakatho Ireland.
