Got a callfrom a South Dakota number?

A South Dakota 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.

Need to call your bank or an office back from abroad? GlobCall calls the official number from your browser for $0.02/min, instead of the $1 or more a minute many carriers charge.
