Carriers operating in 821
NANPA has assigned 42 821 prefixes (NPA-NXX central-office codes) across 16 rate centers: 64% to wireless carriers, 36% to landline and VoIP operators; 100% are pooled blocks shared by several carriers. 20 prefixes were assigned in the last 12 months (newest 2026-08-06).

What to do about calls from 821 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 821 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 South Carolina
- Unwanted sales calls and robocalls: donotcall.gov (FTC). Scams and fraud: ReportFraud.ftc.gov.
