Busiest 646 prefixes this month

What to do about calls from 646 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 646 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 New York
- 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: New York Attorney General.
- New York 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.
