Stay alert when unknown numbers ring—don't share personal details until you verify the source. If the call seems vague or pushes you toward a quick decision, hang up and research the number online or through a trusted directory. Use call‑blocking apps to filter suspicious inbound calls, and consider registering your line with the national Do Not Call list. Trust your instincts; a legitimate organization will usually provide a callback number or email you can confirm. Document any odd requests and report persistent harassment to your carrier or consumer protection agency for further action.
It's worth noting that the listed information may not be comprehensive, as there could be additional places not included in the list.
