<P> Currently, these numbers are mostly used as the termination points for non-geographic numbers, and by some automated systems such as alarms . As such they are not usually meant to be directly dialled . These numbers have been problematic as some mobile phone operators in the UK do not allow access to these ranges, and there may also be difficulty accessing these numbers from outside the UK . Regulator Ofcom proposes that in future these numbers be released for wider, general - purpose use in up to 70 area codes facing number shortage . In order to avoid confusion with codes beginning with these digits, the area code must always be dialled, even from within the same geographic exchange . Accordingly, if these numbers are eventually released for general use, Ofcom proposes completely removing the ability to dial locally without the area code in areas affected . This occurred on 1 November 2012 for the 01202 area code, which covers Bournemouth . </P> <P> Recently, the carrier TalkTalk have inadvertently released parts of the 020 0011 range to the general public, with these numbers currently being in use . For example, the charity Give a Car used the number 020 0011 1664 for a while, but recently switched to a proper London number . </P> <Ul> <Li> 07xxx xxxxxx--mobile phones and WiFi numbers . </Li> </Ul> <Li> 07xxx xxxxxx--mobile phones and WiFi numbers . </Li>
