Got a callfrom a New Hampshire number?
A New Hampshire area code shows where the number was first assigned, not where the caller is now. People keep their numbers when they move, and scammers often fake local-looking numbers.
- Don’t know the number? Let it go to voicemail.
- Says it’s your bank or a government office? Hang up and call the number on their website or your card.
- Never share codes, passwords or card details with a caller.
- Report scam calls to the FTC.
