Is a call from 01204 a scam?
No area code is a scam code. 01204 is the code for homes and businesses in and around Bolton, and a call from an 01204 number is usually just that.

Judge the call by what the caller asks for: a real bank, courier or council will never mind you hanging up and ringing back on a number you found yourself.
