Imagine receiving a call at 4:40 AM from an unfamiliar number, prompting you to press any key for a "code" before the line drops. This is a classic tactic used in automated scams that aim to verify active lines or harvest keypad inputs. Hang up immediately and avoid interacting with the prompt. Consider blocking the number through your carrier or phone settings, and report the incident to the appropriate consumer protection agency. Keep a log of such calls, especially if they become frequent, and educate household members about the risks of responding to unsolicited requests for digits.
