Getting calls from a 01371 number?
01371 is a legitimate geographic code, so most calls from it are ordinary: local businesses, surgeries, schools, councils and households in the Great Dunmow 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 01371 number on your screen is not proof the call came from Great Dunmow. 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.

01371 area code questions
Where is the 01371 area code?

How much does it cost to call a 01371 number?

Why am I getting calls from a 01371 number?
Most calls from 01371 numbers are exactly what they look like: a business, GP surgery, school or household in the Great Dunmow area. But caller display can be faked, a practice called spoofing, so an unexpected call showing 01371 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 01371 number for my business?
Yes. You do not need an office in Great Dunmow or a phone line from the dominant local provider.
