What to do about calls from 937 numbers

Before you call back

  • Debt reduction is the top named complaint here. Don't pay upfront fees for debt relief; the FTC's Telemarketing Sales Rule bans them. Talk to your lender or a nonprofit credit counselor instead. Read about debt-relief robocalls.
  • Look up the full number above. A missed call from 937 with no voicemail is usually a robocall; anyone who needs you will leave a message.
  • If it looks like a neighbor's number, it may be spoofed. See calls from your own area code.
  • Block repeat callers: iPhone, Android, or your carrier's free filter (Verizon, AT&T, T-Mobile).

Report it in Ohio

  • Unwanted sales calls and robocalls: donotcall.gov (FTC). Scams and fraud: ReportFraud.ftc.gov.
  • Spoofing, texts and call-blocking problems: FCC consumer complaints.
  • State complaints: Ohio Attorney General.
  • Ohio formally adopted the FTC's National Do Not Call Registry as its own state list rather than running a separate one, so a single free registration at donotcall.gov covers you. State authorities can still enforce against telemarketers who ignore it, in addition to any federal penalty.
