What 020 tells you about the caller
020 is the area code for London landlines. It shows where the number was first issued, which isn't necessarily where the caller is now: internet phone services and call diverts let people use a local number from anywhere.
Calling back: Calling an 01 or 02 number costs the same as any UK landline call, and it normally comes out of the inclusive minutes on your landline or mobile plan.
If a call starts with 020, the line was issued in London. It is one of only five three-digit UK area codes (the others being 023, 024, 028 and 029), so the local number after it has eight digits. It is part of England. Who Called Me Check holds 4718 020 numbers that people have looked up. Callers can make 020 appear on your screen even if they are nowhere near the area, a trick known as neighbour spoofing. Whatever the code, hang up on any caller who asks for card details, passwords or a one-time code, and ring the organisation back on a number you've found yourself. All 020 numbers
Bear in mind that the number on your screen can be faked. Scammers can make a call look as though it comes from a local landline or even a real company's number, a trick known as spoofing. The caller's script tells you more than the digits do.
How the rating is worked out
The score at the top of this page uses only what you can see here:
- Spam, Scam and Neutral ratings from people who got a call from it
- Written reports describing those calls
- The Ofcom numbering plan entry for this range
- Any scam type the number has been tied to
There are no ratings yet, so the score is blank. That's not a sign the caller is trustworthy, just that nobody has reported it.
