    I've seen a telephone number that I don't recognise

    • Answer

    • There is a National Numbering Plan in the UK that is designed to be easy to understand and consistent across the country. The plan shows what numbers are used by different types of service. Depending on what TalkTalk package you have bought, the prices will vary and we recommend that you look to www.talktalk.co.uk/pricing for more detailed information about the price of calling from a TalkTalk line.

      If you still have questions about a number on your bill, you can get further detail on our Common Number page talktalk.co.uk/commonnumbers. Just type in the number at the top of the page and it will explain a non-geographic number (e.g. business, government, discounted numbers etc). The table below shows the major categories of numbers.
