Is a call from 0121 a scam?
No area code is a scam code. 0121 is the code for homes and businesses in and around Birmingham, and a call from an 0121 number is usually just that. What the code cannot tell you is who is calling, and a scam call can show an 0121 number as easily as any other. 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.

Does 0121 tell me who called?
No. 0121 is assigned to Birmingham, but that doesn’t prove who is calling or where they are. Caller ID can be faked, a number keeps its code when it moves provider, and 176 phone companies hold ranges of 0121 numbers. Search the full number to see what people have reported about it and which phone company its range was given to.
Caller says they’re your bank, HMRC, the police or a courier? Hang up and call a number you trust, from your card, a letter or their website, or dial 159 for most UK banks.
Ofcom keeps 0121 496 0000 to 0121 496 0999 for TV and film. Those numbers can never connect, so if one called you, the caller ID was faked.
Why so many different callers show 0121
Many phone companies hold ranges of 0121 numbers (the count from Ofcom’s data is in the table above), a number keeps its code when it moves company, and internet phone services sell local numbers to businesses based anywhere. If the calls keep coming from different 0121 numbers, blocking one will not stop the next: how to stop spam calls covers the TPS, blocking and reporting, and numbers several people have reported lists the ones reported from more than one network.
