What to do about calls from 813 numbers

Before you call back

  • Impostor (government, business, family) is the top named complaint here. Hang up and call the agency, bank or relative back on a number you already know. Government agencies don't demand payment by gift card, wire transfer or crypto. Read about Social Security impostor calls and fake bank fraud calls.
  • Look up the full number above. A missed call from 813 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 Florida

  • 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: Florida Attorney General.
  • Florida is one of the states that maintains its own Do Not Call registry alongside the federal National Do Not Call Registry, so telemarketers calling Florida numbers are expected to check both lists. Registering on the federal list at donotcall.gov is free and never expires; the state list is administered separately and may have its own registration process and renewal period.
