What kind of number is 020 3930 8164?
(020) 3930 XXXX is a number block in London, an area with a population of approximately 9,540,000. Standard landlines in this area use the format 020 3930 1234, with the first part being the dialling code and the rest being the local number.

Magrathea Telecommunications Limited either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single (020) 3930 XXXX prefix can be used by many different organisations.

Is it safe to answer or call back 020 3930 8164?
One important caveat applies to every UK number, including this one: caller-ID spoofing means the number you see is not guaranteed to be the line actually calling. If a call from 020 3930 8164 claims to be your bank, HMRC or a delivery company and asks you to act urgently, hang up and contact the organisation directly using a number you've verified yourself — for banks you can simply dial 159.
What to do if 020 3930 8164 called you
- Don't act on the call alone. If the caller claimed to be your bank, HMRC, a courier or a utility, hang up and contact the organisation on a number you find yourself — never one the caller gives you. For banks, dial 159.
- Never share security details. Full passwords, PINs and one-time passcodes are never requested by legitimate UK organisations on an outbound call.
- Don't return a missed call you don't recognise. One-ring 'wangiri' scams rely on call-backs, sometimes routed to premium-rate lines.
- Report what happened. Use the report form above to warn other UK users, and report fraud attempts to Action Fraud (or 101 in Scotland).
- If money or details were given, contact your bank immediately on 159 and report to Action Fraud.

About (020) numbers
Numbers in blocks like (020) 3930 XXXX are sometimes spoofed by overseas call-centres using VoIP. Spoofing makes a foreign call appear to come from a UK landline — including the area code where you live. If you don't recognise the number and the caller asks for any personal data, hang up and call the organisation back on a number you know is genuine.
