Is it getting worse?
276 FTC complaints about 586 numbers in the last four weeks; leaving out the concentrated source below, complaints are up 1% on the four weeks before. FCC complaints about 586 numbers peaked in 2018 (248); 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' 586 complaints (12%) came from one place, New Haven, MI (callers' own phones in area code 586), about 7× the state's per-resident rate. That pattern usually means one or a few very active filers, so trend figures here leave it out.

What to do about calls from 586 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 586 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 Michigan
- 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: Michigan Attorney General.
- Michigan 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.
