The BT Phonebook was a free online UK phone directory search by British Telecommunications. BT also provided a free paper copy of the phone book for the region to customers.

Although BT has discontinued the printed versions of their phonebooks, they continue to offer free access to digital versions in PDF format, making it easy and environmentally friendly to search for people.

To find someone using this service, you can download the relevant A-Z Directory PDF for your area or the area where the person you are trying to find resides. These directories include both residential and business listings organized alphabetically, providing names, addresses, and phone numbers where available. BT divides its directories by local regions, including cities and counties such as Aberdeen and Shetland, Birmingham, Brighton, Cambridge, Edinburgh, London, Manchester, and many more, covering a broad geographic range throughout the UK.

Once you download the appropriate directory, you can search through it by name to find the contact information of individuals living or businesses operating within that locality. This is particularly useful if you want to reconnect with an old friend, verify a contact, or find a local service provider.

Furthermore, the directories are updated digitally, so you are accessing relatively current information. The free PDF directories remain available for download from BT’s official website indefinitely even though printed copies will only be sold until 2025, reinforcing the shift towards digital.
