Is it getting worse?
251 FTC complaints about 563 numbers in the last four weeks; leaving out the concentrated source below, complaints are up 5% on the four weeks before. FCC complaints about 563 numbers peaked in 2016 (161); the FTC's daily Do Not Call data has carried most of the volume since mid-2026.
Data note: 34 of the last four weeks' 563 complaints (14%) came from one place, Cresco, IA (callers' own phones in area code 563), about 14× the state's per-resident rate. That pattern usually means one or a few very active filers, so trend figures here leave it out.

Carriers operating in 563
NANPA has assigned 388 563 prefixes (NPA-NXX central-office codes) across 109 rate centers: 25% to wireless carriers, 70% to landline and VoIP operators; 71% are pooled blocks shared by several carriers. 2 prefixes were assigned in the last 12 months (newest 2026-06-03). 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 563 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 563 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 Iowa
- 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: Iowa Attorney General.
- Iowa 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.
