• Q. Why can't I find my phone number?

    About 70% of residential telephone numbers are ex-directory or unlisted.

    Other reasons include:

    • Spelling errors in your listing.
    • You made a spelling error in your search.
    • Your phone number is listed in your partner/spouse/house-mate's name.
  • Q. What data is included in your phone book?

    We receive a daily update from every UK telecom licensed operator that contains all listed white pages telephone numbers. Very few mobile phone numbers are listed anywhere.

  • Q. Are you General Data Protection Regulation (GDPR) compliant?

    Yes, you can view our GDPR statement here.

  • Q. What other searches can you do on ukphonebook?

    Our service was originally just a telephone directory – hence the name. But over the years, we have added many more sources of information.

    Phone Numbers
    BT is the major provider of telephone services in the UK, but not the only one. Our telephone directory is updated every day with information from ALL of the UK telephone operators like KCOM, Virgin, BskyB, Talk Talk Group etc.

    The UK, unlike the USA, does not have a formalised addressing system. This means that it can sometimes be difficult to identify the correct postal address for a given location.

    By 1974, every delivery address had been allocated a 'Postcode' and our service uses data from The Royal Mail (Postal Address Finder) and Ordnance Survey (AddressBase) to provide a means by which you can identify correct address and postcode information. It also provides geographic location information in the form of 'Northings' and 'Eastings' – a system in common use by businesses in the UK.

    Electoral Roll
    Every person of voting age in the UK is required to register with their local authority for the Voter's Roll or Electoral Roll as it is known. This information is used by public bodies and licensed credit reference agencies to provide information on persons over the age of 18.

    A 'sub-set' of the full Electoral Roll is the Edited Electoral Roll. This is derived from the full Electoral Roll, but individuals who prefer their information not to be made public can choose to have their record supressed. It is The Edited Electoral Roll (plus information from certain other consumer databases) that is available to our users.

    Area Codes
    The UK telephone system is divided up into a network of Exchanges. These exchanges are situated near to population centres and all landline telephones are connected to a local exchange. In order to route your telephone call effectively, each exchange will be linked to an area (or STD) code.

    You can use our service to identify the correct area code for a city, town or village OR identify the cities, towns and villages served by a particular area code.

    Company Search – Director Search – Credit Reports
    We obtain detailed company information from various sources including Companies House, CreditSafe, Intelligent Data Group and others to provide a comprehensive search and reporting service on businesses and company officers (Directors, Company Secretaries etc.).

    Use this service to identify the registered information on businesses throughout the UK, identify the individuals responsible for that firm's governance and produce (where available) a detailed credit report and credit-worthiness rating for the business.

    Internal Directory
    We offer the facility to our commercial users to have their company's Internal Telephone/Contact Directory incorporated into the ukphonebook service. Please contact us for more information on this service.

    ZoneSearch is a powerful marketing tool that allows a user to create marketing lists of people and/or businesses that they may wish to promote their business or service to. The information provided may include Name, Address, Telephone Number, Fax Number, Email Address, Business Contact Name and far more.

    It is open for anyone to use and completely free to register and generate lists. Payment for the data is by credit card or invoice (subject to credit check). Please contact us for further information or to apply for a credit account with us.

    The Telephone Preference Service (TPS) is the official central opt out register on which you can record your preference not to receive unsolicited sales or marketing calls. It is a legal requirement that all organisations (including charities, voluntary organisations and political parties) do not make such calls to numbers registered on the TPS unless they have your consent to do so.

    Use our service to check individual numbers or upload your entire tele-marketing file to bulk check your numbers and have the file downloaded to you. It is a legal requirement for tele-marketers to screen their customer file at least every 28 days.

    or 'bulk-processing' is an automated service we offer which can update and verify your customer database.

    Direct marketing can be very expensive so it makes sense to ensure that your customers are still 'live' and the information you have is current and correct. With our fully automated Teleappending service, you simply upload your file (in .csv format), match the headings correctly and click the 'Process' button. Please contact us for more information on this service.

    Google Maps with full-screen access to Street View is included free of charge – but with a difference.

    Every Name and/or address record includes a link to the maps with the ability to send those details and the map link to a friend or colleague via email or text message. Invaluable if you're involved in setting up meetings etc.

    Land Registry
    We have integrated information from the Land Registry with our own data sources so that you can find title deeds (including plans) as well as contact information for the owner(s) of a property.

  • Q. How current is the data?

    The data is updated daily and updates include such things as amendments to existing records, newly inserted records and the removal of no longer required records - If the phone number is listed, we have it.

  • Q. Do I need to use capital letters?

    You can enter text as uppercase or lowercase, searches are not case sensitive. It will also ignore any punctuation e.g. O'Neill will be treated as oneill, d'arcy will be treated as darcy.

  • Q. Can I perform wildcard searching?

    Yes. A wildcard is a character that forces the search to ignore part of the input. Suppose you were looking for someone called John Martinson. If you enter mart* in the surname box, the search will return the following names: Martin, Martindale, Martinez, Martini, Martins, Martinz, Martlew and Martyn.

  • Q. I cannot find somebody that I know is on the electoral roll.

    Unfortunately data protection regulations in the UK mean that we are not permitted to show the full electoral roll. We show the edited electoral roll, in which voters may choose to not be listed.

  • Q. Can my personal data be removed from this site?

    We acquire information from a number of 'opted-in' sources. If you would like us to remove information that relates to you, please complete the Record Removal Request Form.

    Please note that this will only remove your information from our sites. If your information appears on other websites, you would need to approach them separately.

  • Q. I haven't received my verification email. Where is it?

    Unfortunately, verification emails are sometimes blocked or filtered into your spam folder by some Internet Service Providers. An alternative way to verify your account is to send a blank email to moc.koobenohpku@sremotsuc from the email address you registered with. Your account will usually be verified within 5 minutes.

  • Q. Do you have any voucher codes?

    We do occasionally offer voucher codes, these are published on our Facebook and Twitter pages.

  • Q. Who are Simunix?

    We were the first non-telecom company to license the UK's national directory database and in 1999 became one of the first to set up a free online directory enquiries service - Besides directory enquiries we also provide marketing data and data cleansing services, visit our website at for more information.

  • Q. What is T2A?
