Busiest 770 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.

|---|---|---|---|---|
| (770) 847-xxxx | 18 | 18 | BellSouth (AT&T) | Atlanta Northeast |

Carriers operating in 770
NANPA has assigned 784 770 prefixes (NPA-NXX central-office codes) across 43 rate centers: 18% to wireless carriers, 82% to landline and VoIP operators; 43% are pooled blocks shared by several carriers. 4 prefixes were assigned in the last 12 months (newest 2026-05-19).

What to do about calls from 770 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 770 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 Georgia
- 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: Georgia Attorney General.
- Georgia 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.
