What to do about calls from 248 numbers
Before you call back
- Medical & prescriptions is the top named complaint here. Don't confirm your Medicare or insurance number to a caller. Medicare won't cold-call you to sell braces, test kits or plans. Read about Medicare scam calls.
- Look up the full number above. A missed call from 248 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 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.
