Frequently asked questions

What is a phone number lookup?

A phone number lookup tool combines public and private sources to identify phone number meta data, carrier details and associated services the phone number may have been used for in order to find the identity of the caller and provide a safety assessment.

Why should I check unknown phone numbers in the UK?

According to the BBC, 48% of landline users in the United Kingdom reported receiving a suspicious call in the previous three months. These calls can be anything from spam calls to calls with the intention to scam or defraud people. If you have received a phone call from an unknown number, it is a good idea to find out who is behind the call and to report the number.

If the caller knows information about me, does that mean that they are legitimate?

No! Scammers have various methods to obtain personal information of their victims in order to convince them that they represent legitimate companies. Do not fall for this. If you are in doubt it is always best to just hang up the call and call the company that the unknown caller was claiming to be from via its official number. You can also use our phone number lookup to double check the phone number.

How do I know if a phone call is a potential scam?

Scam callers often use disposable phone numbers via Voice over internet protocol (VOIP) services. Our phone number checker detects when phone numbers are VOIP calls which is a strong indication that the caller could be calling with malicious intent. Furthermore, we also check fraud and spam databases to see if the number has previously been reported.
