Busiest 820 prefixes this month
FTC complaints in the last 30 days, grouped by the first six digits. When one prefix collects complaints about many different numbers, a campaign is usually cycling through that block. The carrier is who NANPA assigned the prefix to, not who made the calls.

Carriers operating in 820
NANPA has assigned 98 820 prefixes (NPA-NXX central-office codes) across 31 rate centers: 35% to wireless carriers, 63% to landline and VoIP operators; 99% are pooled blocks shared by several carriers. 13 prefixes were assigned in the last 12 months (newest 2026-09-25). 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 820 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 820 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 California
- 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: California Attorney General.
- California 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.
