Expert Opinion

Watch out—calls from +1 608‑371‑6666 are a red flag. This number is repeatedly used as a spoofed gateway for various telemarketing and scam scripts that slip past call‑blocking services like Nomorobo. Callers often hide their identity, use heavy accents, and shift quickly to a different script after one ring, making it hard to verify who’s on the line. The safest move is to let the call go to voicemail, never share personal or financial details, and report the number to your carrier or the FTC. Keep your blocker active and consider adding the line to any personal do‑not‑call list.
