What the site does

Who Dialled describes UK phone numbers using public data: the type of number set out in Ofcom’s National Telephone Numbering Plan, the phone company a block of numbers was allocated to according to Ofcom’s numbering data, the area of a geographic number according to Ofcom’s list of area codes, typical call costs from Ofcom’s guide, and links to the official services that deal with scam and nuisance calls. It is free to use and does not require an account.

Limits of the information

  • The site does not identify the person or business using a number. Ofcom allocates blocks of numbers to phone companies and does not hold information on individual numbers.
  • The phone company shown is the one Ofcom allocated the block to. A number can since have moved to another provider.
  • The number shown when someone calls you can be faked. A result about a number says nothing about who actually made a call.
  • Data is refreshed from Ofcom’s files, which Ofcom aims to update every Wednesday; there can be a delay before a change appears here. Call costs are typical ranges; your provider’s price list applies.
  • The site gives general information, not legal or financial advice. If you have lost money or shared details, contact your bank and the official services listed on each page.

Acceptable use

Do not use the site to harass anyone, or to collect information about people. Automated mass querying of the site is not permitted.

Data source and copyright

Number data comes from Ofcom’s “Download numbering data” files and “Telephone area codes” list, © Ofcom copyright, reproduced under Ofcom’s terms for re-use of its material. Who Dialled is not affiliated with or endorsed by Ofcom. The site’s own text and design belong to GO TO AGENCY.

Advertising

Information pages show advertising from Google AdSense. Ads are chosen by Google, not by us, and an ad is not a recommendation. Result pages for a checked number carry no ads.

Liability

We take care to reproduce official data accurately, but we cannot guarantee that it is complete or up to date, and we are not responsible for decisions made only on the basis of the site. Nothing in these terms limits liability that cannot be limited by law, or affects your statutory rights as a consumer.

Law

These terms are governed by French law. This does not take away the protection you have under the mandatory consumer laws of the country where you live, and you can bring a claim in the courts of that country.
