Getting calls from a 01476 number?
01476 is a legitimate geographic code, so most calls from it are ordinary: local businesses, surgeries, schools, councils and households in the Grantham 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 01476 number on your screen is not proof the call came from Grantham. 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.

01476 area code questions
Where is the 01476 area code?
01476 is the dialling code for Grantham. The code and the areas it serves are set by Ofcom, the UK communications regulator.
How much does it cost to call a 01476 number?

Why am I getting calls from a 01476 number?
Most calls from 01476 numbers are exactly what they look like: a business, GP surgery, school or household in the Grantham area. But caller display can be faked, a practice called spoofing, so an unexpected call showing 01476 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 01476 number for my business?
Yes. You do not need an office in Grantham or a phone line from the dominant local provider.

Existing 01476 numbers can be ported in: porting is included on Landline SIM plans, or a one-off £20 + VAT on Virtual Landline.
