Finding UK Phone Numbers: Best Directories & Methods (2024)

Looking for a UK phone number? Here are the most effective current methods:

1. Online Directories (Best for Most Searches)

• BT Phonebook (bt.com/phonebook) – Official, comprehensive (landline + mobile opt-in)
• 192.com – People, businesses, addresses; advanced search (paid for full)
• Yell.com – Business-focused; reviews, maps
• The Phone Book (thephonebook.bt.com) – Legacy brand, same data as BT

2. Search Engines

• Google: "name + location + phone" or "business name + phone"
• Use quotes for exact phrases; add "site:linkedin.com" for professionals

3. Social Media & Professional Networks

• LinkedIn: Best for professionals (many list contact info)
• Facebook: "About" → Contact Info (if public)
• Twitter/X, Instagram: Bio sometimes includes phone

4. Mobile Operator Directories

• Each UK carrier (EE, O2, Vodafone, Three) has internal directory—usually opt-in only
• Not publicly searchable

5. Printed Directories (Declining)

• BT still prints The Phone Book for some areas—libraries, post offices, community centres
• Yellow Pages ceased print (2019)

6. Specialized

• Companies House: Director addresses (not phones)
• NHS / GP finder: For doctors
• Law Society / Bar Council: Solicitors/barristers

Tips

• Many people don't list landlines anymore—mobile only
• GDPR: Individuals can opt out of directories
• For businesses: Google Maps / Yell / Companies House most reliable
• If urgent: Try multiple methods; no single source is complete

Start with BT Phonebook + Google—covers 80% of needs.
