03 - Landlines, Non-geographical Numbers

Phone numbers that start with the “03” phone code are non-geographic numbers used for businesses and other organizations. They are not linked to any specific location, which makes them a more flexible alternative to area-specific landline codes like 01 or 02.

Businesses and organizations use non-geographic numbers instead of regular local landlines because they allow for some special features. Non-geographic numbers allow for flexible routing that lets calls be directed to any destination. This means that people can feel more at ease calling a local number, even though the call can be answered at a different location.

Using an 03 area code also makes it easier for organizations or businesses to advertise a single number, even if they cover multiple locations. Calls can then be forwarded to the office closest to the caller’s location, which allows them to have a more seamless customer service experience.

03 area codes are also invaluable when it comes to disaster recovery efforts. Standard, geographically based landline numbers can become unreachable in the event of a disaster that damages the telephone number in the linked area. If a number isn’t linked to a geographic location, incoming calls can be redirected to another location when needed.

Use of 03 area codes

While all 03 area code numbers function the same and cost the same, there are some sub-ranges that have restrictions on their use. 034 and 037 prefixes are reserved for migration from the equivalent 084 and 087 numbers, and 030 prefixes are only for use by public sector entities and NGOs like registered charities. There are currently twelve 03 number prefixes available.

History of 03 area codes

03 phone numbers were introduced in 2007 by telecom regulators, Ofcom. Before the introduction of 03 numbers, any company that wanted the call routing specialties listed above would have to use either a toll-free number or use a range of 08, non-geographic numbers. Not only was this expensive for the organization to run, but it was also expensive for people to call. 03 prefixes allowed companies to get the full range of calling features while not costing callers more than a normal phone call.

The convenience of this feature didn’t fully take off until 2014, when the EU's Consumer Rights Directive banned the use of expensive 084 and 087 numbers for customer service lines, with similar rules put in place for banks for the following year. This led to many companies switching over to 03 numbers during those two years.

Cost of calling 03 numbers

Any number in the UK starting with the 03 area code costs the same to call as any normal ‘01’ or ‘02’ landline number and is included in calling packages as such. It is actually a legal requirement that 03 numbers are charged at the same rates as normal landline numbers and that they cannot generate profit for the call recipient.

Typical rates for 03 numbers are about 16p per minute, with most providers charging a 23p connection charge (though this can vary). Call charges can depend on the time of day the call is placed and the call package the person has.
