However, this could prevent new friends or colleagues from getting in touch. Contacting your carrier by phone or email to discuss your options. Put your number on the federal Do Not Call list.

However, with many scam artists out there, it's important to proceed with caution.

One scam going around right now is spoofing, in which a hacker takes someone's phone number and uses it to call others. Usually, this won't come up as unknown because the scammers enter phone numbers of people they are pretending to be, but be cautious because you never know what the newest scam is from day to day.

Another phishing scam occurs when an unknown caller fills up your missed-call screen, but the number shows up under an unknown name. They want you to call back so they can charge you for the call and for each minute you remain on the call. They usually let the phone ring once so it's enough to show up in your call log but not long enough for you to answer.
