Non-geographic telephone numbers in the United Kingdom

UK phone number not linked to a location

A non-geographic number is a type of telephone number that is not linked to any specific locality. Such numbers are an alternative to the traditional 'landline' numbers that are assigned geographically using a system of location-specific area codes. Non-geographic numbers are used for various reasons, from providing flexible routing of incoming phone calls to generating revenue for paid-for services.

01Functionality

Non-geographic numbers were introduced to offer services that were historically unavailable on standard landline phone numbers, particularly in terms of call routing and special charging arrangements. Advertised benefits of non-geographic numbers include:

  • Call routing. Calls can be flexibly redirected to virtually any destination. For example, calls could be answered in different call centres depending on where the caller is located or the time of day.
  • Ease of communication. Organisations covering multiple locations can advertise a single national phone number rather than having to publicise different numbers for different areas.
  • Location neutrality. Standard geographic numbers are firmly linked with specific localities. Using non-geographic numbers can help an organisation avoid appearing to be limited in scope to a specific geographic area, and also removes any need to change telephone numbers in the event of relocation or expansion into a different area.
  • Resilience and disaster recovery. Standard geographically routed landline numbers may become unreachable in the event of a fault or damage to the telephone network in the area they are linked to. Non-geographic numbers allow for incoming calls to be easily redirected to alternative locations when necessary.
  • Special charging arrangements. The use of number prefixes that are distinct from standard landline numbers allows for a variety of different charging arrangements, from freephone numbers that cost the caller nothing to dial to premium rate numbers that generate revenue for the called party.

Call handling

Calls to non-geographic numbers are handled in various different ways by the telephone network. In the simplest case, calls are simply forwarded to a regular geographic number and routed by the telephone exchange in the normal way. In other cases, such numbers may channel calls directly to a company's private telephone system or VOIP service.

Developments in telecoms technology mean that advanced call routing facilities are no longer unique to non-geographic numbers with many suppliers offering the same functionality through 'virtual' geographic numbers.

Calling non-geographic numbers from abroad

Calling certain non-geographic number ranges might not be possible when calling from abroad of the United Kingdom. This is mostly the case with the 070 personal numbering range, the 080 freephone range and service numbers starting 084, 087, and 09.

02Non-geographic number ranges

All non-geographic numbers offer similar functionality, with the main difference being the charge levied on the caller. The major non-geographic prefixes now in use are:

080 (freephone)

0800 and 0808 numbers are free-to-caller from landlines, mobile phones, and payphones alike. The organisation receiving the call pays the cost of the call.

03 numbers

Billing and costs

Numbers starting with '03' are non-geographic numbers charged at standard geographic rates. Calls to these numbers cost exactly the same as calls to regular local or national landlines (those starting with 01 or 02). Regulation ensures that if a tariff offers inclusive minutes or free calls to numbers starting with 01 or 02, calls to 03 numbers must be included on exactly the same terms.

Since their reintroduction in 2007, these 03 numbers have been the only variety of non-geographic number whose charge is officially linked to that of geographic numbers. No provision has been made for replicating the old 'local rate' or 'national rate' prefixes, as almost all UK telephone operators now charge all landline calls at the same rate, regardless of location.

Usage

As of 2016, active 03 number prefixes are: 0300, 0303, 0330, 0333, 0343, 0344, 0345, 0370, 0371, and 0372.

While all 03 numbers operate the same way, some sub-ranges have restrictions on their use.

030
Reserved for allocation to public sector bodies and not-for-profit bodies such as registered charities
034 / 037
Reserved for migration from equivalent 084 and 087 numbers.

Service numbers

These are the non-geographic numbers starting 084, 087, and 09. They are also known as premium rate numbers. Until 2015, 084 and 087 numbers were called special rate or business rate numbers.

Since 2015, these numbers have a two-part charging structure. Call charges consist of a per-minute access charge levied by the caller's phone service provider, plus a service charge or 'premium' paid to the joint benefit of the organisation being called and their telecoms provider.

The access charge varies considerably by phone operator, with calls from landlines charged at 2p to 27p per minute and calls from mobile phones charged at 4p to 89p per minute.

The service charge is charged at the same rate regardless of which telephone company the caller uses to make the call. The rate that applies must be detailed wherever the number is publicised and falls into the following bands:

  • 084 numbers: up to 7p per call and/or 7p per minute
  • 087 numbers: up to 13p per call and/or 13p per minute
  • 09 numbers: up to £6.00 per call and/or £3.60 per minute.

There is no official central repository for Service Charge information, but the Federation of Communications Services (FCS) has provided an interactive online facility to look up the Service Charge for any 084, 087, 09, or 118 number.

Service charge price points

Upon introduction of the "unbundled tariff" for calls to 084, 087, 09, and 118 numbers on 1 July 2015 there were 80 price points for the Service Charge element of the call cost. These were designated SC001 to SC080. A further 20 price points, designated SC081 to SC100, were added on 1 July 2016. There were 100 price points until 1 April 2019. The same charges apply to calls made from all landline and mobile providers.

Zen Internet charged six of the price points at the wrong rate, three from 1 July 2015 until their withdrawal on 1 April 2019 and three more from 1 July 2016 to January 2019. From 1 July 2016 to 26 December 2016, Sky Talk charged three of the Service Charge price points at the wrong rate. From 30 November 2016 to 14 March 2017, Sky Mobile charged three of the price points at the wrong rate. Virgin Media did not list price points SC081 to SC100. Andrews & Arnold did not list price points SC068 to SC072, SC080 or SC081 to SC100. Origin Broadband did not list price points SC081 to SC100.

On 1 April 2019, Ofcom introduced a price cap (on the Service Charge element of the call cost) of £3.65 per 90 seconds of a call on calls to numbers starting 118. From this date, 26 of the existing 100 Service Charge price points were no longer available for use by services on telephone numbers starting 118. Of those 26 price points, some 15 price points were available only for use by services on numbers starting 09, and eleven price points were withdrawn from use. From 1 May 2019, new price points started to be introduced. These re-used some of the previously withdrawn SC code numbers, all as noted in the table below.

Notes

Personal numbers

Numbers starting 070 are "personal numbers" , virtual telephone numbers intended to offer non-geographic number functionality to individuals, such as by allowing people to have a single number that directs calls to their home, work or mobile phone as they choose. They are controversial as they are charged at premium rates and can be confused for mobile numbers, and therefore the cost of calls to them may not be apparent to callers until they receive their bills.

From 1 October 2019, Ofcom capped the termination rate for these calls at the same rate as for calls to UK mobile numbers, thereby allowing phone providers to include these calls within monthly allowances or otherwise charge them at the same rate as a call to a mobile number.

Controlled Premium Rate Services

A subset of non-geographic numbers, designated Controlled Premium Rate Services (CPRS), is subject to additional regulation by the Phone-paid Services Authority (PSA), formerly PhonepayPlus.

Ofcom's "PRS Condition" defines Controlled Premium Rate Services as those:

  • using "unbundled tariff numbers" starting 087, 090, 091, 098 or 118 with a Service Charge of more than 7p per call or per minute inclusive of VAT,
  • using other numbers where the termination fee or rate is more than 10p per call or per minute inclusive of VAT (covers numbers starting 070 and 076 and various mobile shortcodes),
  • providing a chatline service, irrespective of call cost or prefix used,
  • providing an adult-entertainment service, irrespective of call cost or prefix used,
  • is an internet dialler-operated service, irrespective of call cost or prefix used.

From 16 January 2019, all Information, Connection and/or Sign-posting Services (ICSS), irrespective of call cost or prefix used, were added to this definition.

Services identified as CPRS must comply with the PSA Code of Practice.

03History

Most non-geographic numbers use prefixes recovered from former use as geographic area codes. For previous uses of prefixes such as 0345, 0800 and 0990, see: List of dialling codes in the United Kingdom.

Freephone, including 0800 and 0808

During the 1980s, free-to-caller numbers were introduced using a range of prefixes that had previously been used as geographic area codes. By the 1990s, the prefixes 0321, 0500 and 0800 were all in use and allocated to Vodafone, Mercury Communications and BT respectively. Typically, the relevant prefix was followed by a six-digit number, giving a total number length of ten digits including the initial '0'.

Increased competition and a shortage of the popular 0800 numbers in the early 1990s saw various strategies employed to increase freephone capacity. Newly issued 0800 numbers were lengthened to include seven digits after the 0800 prefix, and the additional 0808 prefix was introduced during 1997. Also during the 1990s, deregulation allowed companies other than BT to acquire 0800 numbers and issue them to their customers, as well as allowing customers with existing freephone numbers to retain them when changing telecoms supplier.

With the 0800 and 0808 ranges established as the primary freephone ranges, the 0321 number range was withdrawn during 2001. The 0500 number range will be withdrawn during 2017, with users migrated to 0808 5 numbers.

Major mobile phone operators went through a period of charging callers to dial most freephone numbers from around 2005 onwards, but this practice largely ceased on 1 July 2015 as 0800 and 0808 numbers became universally free to call from mobiles and landlines due to changes in Ofcom legislation.

As a freephone call results in no charge to the caller, the organisation receiving the call pays the call cost.

03 Numbers

The original range of telephone numbers starting '03' was progressively cleared between 1995 and 2001: former geographic area codes starting 03 were renumbered to start 013 during the national PhONEday renumbering, while premium rate, local rate and mobile phone prefixes such as 0331, 0345, and 0378 were transferred to a simplified structure of 09, 08 and 07 numbers. The 03 numbering range was then designated as available for any new geographic area codes that might be created during further renumbering.

With no further geographic renumbering undertaken, the 03 numbering range was no longer required for its original purpose and was instead redesignated for "non-geographic numbers charged at geographic rate" service in 2006. Telecoms regulator Ofcom introduced the range as it believed that some organisations would benefit from a type of non-geographic number that did not impose any additional charges on callers, and that some consumers were confused about charges for existing special-rate numbers starting 084 and 087.

The decision to introduce the new 03 range followed a period in which increased competition in the telecoms market had brought considerable change to the way in which calls were charged for. When first introduced in the 1980s, special 'local rate' and 'national rate' non-geographic prefixes (such as 0345, 0645 and 0990) had been charged at exactly the same rate as normal local and national geographic calls. Telecoms deregulation saw several more landline providers enter the market and call packages with "inclusive" minutes to 01 and 02 numbers started to become the standard offering after 1999. While BT's charges for calls to non-geographic numbers were capped, most call packages did not include calls to non-geographic numbers, and other landline providers and mobile operators were free to charge whatever they liked for these calls. In time, a situation developed where supposedly 'local' and 'national' rate prefixes (which by 2001 had been renumbered to begin 0845 or 0870) frequently cost more to call than a genuine local or national landline. By 2004, the situation had become even more complicated as most telephone companies abandoned any distinction between local and national rate calls and began charging geographic landline numbers at a single rate. The new 03 number range had none of these ambiguities or complications and allowed organisations to once again advertise non-geographic numbers that were consistently priced and did not result in callers paying a premium.

Service Numbers starting 084

After the national PhONEday renumbering in 1995, the first new use of numbers starting 084 was in 1996 when 0845 numbers were introduced for non-geographic services charged at a local rate. These 0845 numbers joined, and eventually replaced, existing local rate prefixes 0345 and 0645 which had been introduced in the 1980s. Telephone companies originally charged these calls at the same rate as local geographic calls.

In 1999, landline providers started to offer "inclusive" call packages where calls to all 01 and 02 numbers are free. However, outside the plan there was no price distinction between local or national calls. In 2004, telecoms companies scrapped the remaining tariffs that had provided a discount for local geographic calls. With this change, "local rate" ceased to exist for all customers. Prices for calling 0845 numbers remained roughly the same as before, but since 2004 the UK Advertising Standards Authority has ruled against every company describing them as "local rate" or "lo-call" numbers. Some operators began to include 0845 numbers in their calling plans, but others, including mobile operators, did not.

In 2000, the 0844 prefix was introduced for use with dial-up internet services (in the range 0844 0xx xxxx) and for general uses charged at a rate of up to 5p per minute (all other 0844 numbers). The 0843 prefix was added to provide additional capacity in 2007. These numbers were never linked to geographic call rate and were never included in call plans; the Advertising Standards Authority has taken action against companies that falsely claim 084 numbers are "local rate" or "lo-call" rate calls.

Prices from BT lines were regulated such that calls to 0843 and 0844 numbers typically cost no more than 5p per minute. However, such calls were not included in calling packages and other landline companies and mobile operators charged a far wider range of prices, typically up to 40p per minute. This charging structure allowed organisations to benefit financially from calls to such numbers, by receiving a percentage of the charge made to the caller.

On 1 July 2015, a simplified universal charging system was introduced for 084 numbers and all other 'service numbers'. Calls to all 084 numbers now consist of a 'service charge' of up to 7p per minute and/or 7p per call, plus a standard 'access charge' set by the caller's own phone company which typically ranges from 7p to 45p per minute. The total call cost therefore typically ranges from 7p to 52p per minute.

The service charge is the portion of the call cost that is received by the organisation being called and/or their number supplier; a variety of different per-minute and per-call rates are available. Organisations are obliged to detail the applicable service charge wherever they publicise their 084 number.

Service Numbers starting 087

The first new 087 numbering range introduced after the PhONEday renumbering of 1995 was the 0870 prefix. Introduced in 1996, this was for non-geographic calls charged at the same rate as national (or 'long distance') calls. It initially existed alongside the older 0541 and 0990 prefixes, before finally replacing them entirely in 2001.

In 2000, a further batch of numbers using the prefix 0871 was introduced for use with dial-up internet services (in the range 0871 0xx xxxx) and for general uses charged at a rate of up to 10p per minute (all other 0871 numbers). In 2007, the 0872 and 0873 prefixes were added to provide additional capacity. In contrast to the 0870 range, neither prefix was linked to geographic rates or included in call packages, with both 0871 and 0872 numbers instead intended to be charged at a typical rate of no more than 10p per minute. In practice, such charging rates applied only from BT lines and calls typically cost 16p per minute from non-BT landlines and up to 45p per minute from mobile telephones.

In 1999, landline providers started to offer "inclusive" call packages where calls to 01 and 02 numbers were free. Within a few years most customers were on this type of plan. The price for calling 0870 numbers continued at roughly the same levels as before, and as they were not usually included in calling packages or free minutes, they effectively became more expensive to call than regular geographic numbers in most cases. Mobile operators also began to charge a higher rate for 0870 calls than for geographic numbers. As a result, the term "national rate" was no longer an accurate description of the price for calling 0870 numbers. The Advertising Standards Authority made several rulings against companies claiming that their 0870 numbers were charged at national rates over the following years.

As with 084 numbers, the charging structure allowed organisations to benefit financially from calls to such numbers, by receiving a percentage of the charge made to the caller.

As 0870 numbers had been adopted on a large scale by public services, healthcare providers, banks, utilities and other companies, the relatively high cost of calling such numbers became a matter of public concern. By 2004, the website saynoto0870.com had been established to help callers find alternative contact numbers for companies, and in 2005 BT suggested scrapping 0845 and 0870 numbers entirely. BT believed the public were being misled about their call prices from other operators and Ofcom proposed removing revenue share from 0870 numbers and capping prices at less than "national rate", but such changes were delayed by several years.

In response to concerns about the continuing abuse of 0870 numbers, Ofcom announced in 2008 that higher charges for 0870 numbers could remain provided that there was an announcement before the call. However, since that announcement Ofcom changed its decision, citing technical difficulties relating to alarm systems, some of which are life critical and due to strong lobbying and pressure from the telecoms industry. From 2009, the ability of organisations using 0870 numbers to receive a proportion of the call cost was removed. However, the cost of calling such numbers continued to vary considerably; some landline tariffs now included 0870 numbers in inclusive allowances, while mobile operators charged a premium for calling such numbers. Many organisations changed to using other 084 and 087 numbers through which they could continue to receive an income from call costs.

From 2008, the higher-rate 0871 and 0872 numbers began being regulated by the premium-rate telecoms regulator, PhonepayPlus.

On 1 July 2015, a simplified universal charging system was introduced for 087 numbers and all other 'service numbers'. Calls to all 087 numbers now consist of a 'service charge' of up to 13p per minute and/or 13p per call, plus a standard 'access charge' set by the caller's own phone company which typically ranges from 7p to 45p per minute. The total call cost therefore typically ranges from 7p to 58p per minute.

The service charge is the portion of the call cost that is received by the organisation being called and/or their number supplier; a variety of different per-minute and per-call rates are available. Organisations are obliged to detail the applicable service charge wherever they publicise their 087 number.

Service Numbers starting 09

During the 1980s and early 1990s, a range of premium rate prefixes were brought into use for a variety of purposes including competitions, recorded information, chat lines and television voting. The BT prefixes 0891 and 0898 became well-known, but a wide variety of other prefixes were also used including 0338, 0660, 0890 and 0991.

From July 1998, numbers starting with 090 were progressively made available for all new premium-rate services. Initially, these were further subdivided by type: 0909 was for adult services, while 0907 was intended to be used as a pay-for-product range.

A year later, on 1 July 1999, the promotion of services using older premium rate prefixes not starting with 090 was prohibited. Finally, in April 2001, all such numbers were permanently withdrawn.

Various new premium rate prefixes starting 090 and 091 have come into use in the years since and Ofcom has now set aside the whole of the 09 number range for use by premium-rate services. The block of numbers starting 098 is reserved for adult services with sexual content (alongside older 0908 and 0909 prefixes).

As with 084 and 087 numbers, a simplified two-part charging scheme was adopted for 09 numbers on 1 July 2015.

04Revenue Sharing and Call Price Indications

The cost of calling non-geographic numbers starting with 084, 087 and 09 usually includes a 'service charge' which allows for the possibility of what is known as revenue sharing.

For any telephone call to a non-geographic number, there are four parties involved: the caller, the originating telecommunications company (or 'telco'), the terminating telco and the called party. The caller pays their telephone bill to the originating telco.

The called party is supplied their non-geographic telephone number by the terminating telco, which will have issued with specific blocks of non-geographic numbers by Ofcom. Each block will have a specific service charge associated with it, for example, numbers starting 0845 748 are BT numbers with a 5p per minute service charge, while those beginning 0871 484 are numbers operated by TTNC Ltd. with a service charge of 10p per call. The called party has complete control over this choice when they pick a telephone number for their business from the available supply.

After covering the cost of routing the call to its final destination, the terminating telco may share some of the remaining "premium" directly with the called party in a revenue share arrangement, or may use those monies to offset the cost of providing other services for the called party.

Revenue sharing is not possible on 0800 and 0808 number ranges due to their free-to-caller nature, and is specifically prohibited for 03 numbers.

Call price indications

The total charges for calls to 084, 087 and 09 numbers consists of two distinct parts, which are intended to be communicated to callers separately:

  • The called party is responsible for informing callers of the 'service charge' they and/or the terminating telco will receive;
  • The originating telco is responsible for informing its customers of the standard per-minute 'access charge' they levy on calls to 084, 087 and 09 numbers.

Previously, the called party was obligated to quote only the call price from BT landlines. For example, for 0844 numbers they would typically state: "calls cost 5 pence per minute from a BT landline, other providers and mobile operators may charge more." As other landline providers and mobile operators often charged significantly more than the tightly regulated BT amount, there was considerable potential for bill shock and confusion.

The called party would now be expected to include a statement such as: "calls cost 7p/min, plus your telephone company's access charge". This removes the ambiguity of the phrase "may charge more" and makes it clear where organisations are choosing to impose a service charge on callers, but does rely on callers being aware of their call provider's access charge to calculate the total price.
