Busiest 304 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 304
NANPA has assigned 785 304 prefixes (NPA-NXX central-office codes) across 228 rate centers: 27% to wireless carriers, 70% to landline and VoIP operators; 65% are pooled blocks shared by several carriers. 1 prefix was assigned in the last 12 months (newest 2026-01-08). 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 304 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 304 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 West Virginia
- 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: West Virginia Attorney General.
- West Virginia does not run its own Do Not Call registry and has not formally adopted the federal list as a state list. The federal National Do Not Call Registry at donotcall.gov still applies to you — register there, free, and it never expires.
