How to Trace a Phone Number in the UK

1. Write down the entire phone number that you want to trace. You must know the land code for the number. The country code for the United Kingdom is +44.
2. Visit a free online mobile phone directory. MobilePhoneNumber.com is an online directory that has a special section specifically for phone numbers that originate from the United Kingdom. Simply enter a phone number, and the directory will show you information from its database.
3. Register with a mobile phone tracing company. A few companies work specifically with mobile phones. For example, TraceAMobile.com allows you to trace mobile phone numbers in the United Kingdom. You will have to pay a monthly fee to use the service.
4. Use a landline phone-tracing company if the phone number doesn't originate from a mobile phone. Investigative Resources can trace landlines from many countries, including the United Kingdom. The company guarantees confidentiality and sets up all payments through PayPal.
