Typical figures. Your provider's rates may differ. Access charges are set by your provider and added on top of service charges.

01 and 02 numbers — geographic

Geographic numbers

Numbers starting with 01 or 02 are geographic landline numbers tied to a specific area of the UK. 020 numbers are in London, 0161 in Manchester, 0121 in Birmingham, and so on. They are included in almost all UK call bundles and are typically free to call.

Businesses, households and public services all use geographic numbers. Note that scammers can spoof geographic numbers to appear local — a familiar-looking area code does not guarantee the call is genuine.

Major area codes

03 numbers — national rate

03 numbers

03 numbers are national rate numbers used by organisations that want a non-geographic number without charging callers extra. They cost the same as calling a 01 or 02 number — included in most call bundles and typically free from mobiles and landlines.

Government departments, NHS services, charities and local councils commonly use 03 numbers. Examples include HMRC (0300 200 3300) and NHS England (0300 311 2233).

Cost: Same as 01/02. Included in most bundles. Free from most UK mobiles.

07 numbers — mobile

07 mobile numbers

Numbers starting with 07 are usually standard mobile numbers. Ranges 07400–07999 are allocated to UK mobile networks. Calling these is included in most mobile plans and many landline bundles.

070 numbers: personal numbers

070 numbers are personal numbering service numbers, not standard mobiles. They can cost up to 65p per minute to call and are frequently used in scams — a caller may leave a missed call from an 070 number hoping you call back at a premium rate. Always check before returning a call to any 070 number.

076 numbers: pager numbers

076 numbers are allocated to paging services. Calls to these numbers may cost significantly more than a standard mobile call.

08 numbers — service numbers

08 numbers

0800 and 0808: Freephone

Free to call from all UK mobiles and landlines. No access charge applies. Many government helplines, banks and charities use 0800 numbers.

0844 and 0845: Service numbers

Cost up to 7p per minute plus your provider's access charge (typically 15–65p/min). Not included in call bundles. Many organisations have moved away from these numbers following widespread criticism of their cost.

0870, 0871, 0872, 0873: Premium service numbers

Cost up to 13p per minute plus your provider's access charge. Not included in any call bundle. Always look for an alternative 01/02/03 number before calling these.

09 numbers — premium rate

09 numbers — premium rate

Warning: very high call cost

09 numbers can cost up to £3.60 per minute from a mobile or landline. They are used for competition lines, chat services and some information services. Never call back an 09 number unless you know exactly what it costs. Scammers sometimes leave missed calls from 09 numbers to trick people into calling back.

09 numbers are regulated by the Phone-paid Services Authority (PSA). If you have been charged unexpectedly, contact your network provider or visit psauthority.org.uk.

116 numbers — free helplines

116 numbers

116 numbers are European harmonised numbers reserved for services of social value. They are always free from any UK phone, including mobiles, and do not count against call bundles.
