Common scam calls from 605 numbers

Scam callers rotate through local-looking numbers because people answer them more often. These are the patterns reported most often across North America and seen with 605 caller IDs.

  • "the IRS or Social Security" threats. A recorded voice claims a warrant or unpaid tax bill and demands payment by gift card or wire. Government agencies do not call from 605 numbers to demand instant payment.
  • Bank fraud alerts. A caller pretends to be the fraud desk of a bank with branches in Sioux Falls and asks you to "verify" a card number or one-time code. Hang up and call the number on the back of your card.
  • Local-looking spoofed numbers. Scammers spoof 605 numbers so the call looks local. A lookup that shows a VoIP line, or a carrier that does not serve South Dakota, is the giveaway.
  • Delivery and utility texts. Texts about a missed package or an overdue Sioux Falls utility bill link to a fake payment page. Trace the sending number before tapping anything.

How to check a 605 number

  1. Enter the full ten-digit number in the panel above. The area code is already filled in.
  2. Read the line type and carrier. A mobile or landline from a carrier that serves South Dakota is usually genuine; a VoIP line spun up yesterday is not.
  3. Check the risk level and community reports. If others have flagged the number, do not call back.
  4. Still unsure? Unlock risk details or the owner report for the number.
