Carriers operating in 861

The carrier holding a prefix is who the number was issued through. It says nothing about who is calling, since caller ID is routinely spoofed.

What to do about calls from 861 numbers

Before you call back

  • Look up the full number above. A missed call from 861 with no voicemail is usually a robocall; anyone who needs you will leave a message.
  • Block repeat callers: iPhone, Android, or your carrier's free filter (Verizon, AT&T, T-Mobile).

Report it in Illinois

  • 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: Illinois Attorney General.
  • Illinois 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.
