Getting calls from a 01433 number?
01433 is a legitimate geographic code, so most calls from it are ordinary: local businesses, surgeries, schools, councils and households in the Hathersage area. Two things are worth knowing before you call back.
First, caller display can be faked. Scammers spoof real UK area codes to look local, so a 01433 number on your screen is not proof the call came from Hathersage. Second, the safe habit is simple: if a caller you were not expecting asks for personal or payment details, hang up and ring the organisation back on a number you found independently.

01433 area code questions
Where is the 01433 area code?
01433 is the dialling code for Hathersage. The code and the areas it serves are set by Ofcom, the UK communications regulator.
How much does it cost to call a 01433 number?

Why am I getting calls from a 01433 number?
Most calls from 01433 numbers are exactly what they look like: a business, GP surgery, school or household in the Hathersage area. But caller display can be faked, a practice called spoofing, so an unexpected call showing 01433 is not proof the caller is really local. If a caller asks for personal or payment details, hang up and call the organisation back on a number you found yourself, for example from its website or a bill.
Can I get a 01433 number for my business?
Yes. You do not need an office in Hathersage or a phone line from the dominant local provider.

Existing 01433 numbers can be ported in: porting is included on Landline SIM plans, or a one-off £20 + VAT on Virtual Landline.
