    Let unknown numbers go to voicemail

    ~35s
    If your phone rings and you do not recognize the number, do not pick up. Let it ring through to voicemail. Legitimate callers — doctors, pharmacies, family members calling from a new number — will leave a message. Scammers almost never leave a genuine voicemail. After the call ends, check whether a message was left before deciding to call back.

    Quick Tip

    If someone leaves a voicemail that sounds urgent (like a warning about your Social Security number or a problem with your bank account), do not call the number in the voicemail. Hang up and call the organization directly using a number from their official website or your bank card.

    Never press any buttons during a robocall

    ~30s
    If you accidentally answer a robocall and hear a recorded message, hang up right away. Do not press 1, do not press 2, do not say "yes" or "no." Pressing any button or speaking confirms to the automated system that your number is active. Your number may then be sold to other scammers, resulting in even more calls.

    Warning

    Scammers sometimes use "yes" or "no" recordings from calls to impersonate you in voice-authorization fraud. If a call asks you to confirm your name or say "yes" to agree to something, hang up.

    Turn on Silence Unknown Callers (iPhone) or Call Screen (Android)

    ~37s
    On an iPhone: go to Settings, scroll down and tap Phone, then tap Silence Unknown Callers and switch it on. Calls from numbers not in your contacts will go straight to voicemail without ringing your phone. On a Google Pixel phone: open the Phone app, tap the three-dot menu in the upper right corner, tap Settings, then tap Call Screen and turn on automatic screening. On a Samsung Galaxy phone: open the Phone app, tap the three-dot menu, tap Settings, then tap Caller ID and Spam Protection and turn it on.

    Quick Tip

    These features do not block calls from your saved contacts, so people you know can still reach you normally.

    4

    Download a free call-blocking app

    ~36s
    Open the App Store (iPhone) or Google Play Store (Android), search for "Hiya" or "YouMail," and install the free version. During setup, each app will ask permission to screen incoming calls — grant the permission so the app can work. Hiya shows a warning banner on your screen when a likely spam or scam call comes in, even before you answer. YouMail can play a "number not in service" message to robodialers, which may cause them to remove your number from their calling list.

    Quick Tip

    Check whether your carrier already provides call-blocking. AT&T Call Protect, T-Mobile Scam Shield, and Verizon Call Filter are free and can be found in your carrier's app or website.

    5

    Register your number with the Do Not Call Registry

    ~36s
    Go to donotcall.gov on your phone or computer. Tap "Register Your Phone" and enter your phone number and email address. The FTC will send you a confirmation email — click the link in that email to complete registration. Your number will be on the registry within 31 days. Registration does not expire, so you only need to do this once per phone number. You can also register by calling 1-888-382-1222 from the phone number you want to register.

    Quick Tip

    The Do Not Call Registry stops legal telemarketing calls. It does not stop scammers, who ignore the law. Use it alongside the call-blocking steps above for the best protection.

    6

    Report scam calls to the FTC

    ~30s
    If you receive a call you believe is a scam, go to ReportFraud.ftc.gov or donotcall.gov/report on your phone or computer. Select "Unwanted Calls" and fill in the phone number that called you, the date and time, and a brief description of what they said. You do not need to give your name. The FTC uses these reports to track illegal calling campaigns and take action against the companies responsible.

    Quick Tip

    Screenshot any texts that accompany suspicious calls and include them in your report. The FTC accepts text message complaints at the same address.

    Robocalls are automated phone calls made by a computer rather than a real person. They can deliver a recorded message, connect you to a live scammer, or play a tone designed to confirm your number is active so you will get called again. The Federal Trade Commission (FTC) estimates that Americans receive billions of robocalls every year.

    Many robocalls are outright scams — fake IRS warnings, Social Security fraud alerts, fake tech support calls, Medicare schemes, and more. But even non-scam robocalls are illegal in most cases. The FTC has rules that prohibit most unsolicited automated calls.

    The key to protecting yourself is knowing what to do (and what not to do) when an unknown number calls.

    The golden rule: let it go to voicemail

    If you do not recognize the number, let the call go to voicemail. A legitimate caller — a doctor's office, a family member calling from a new number, a real business — will leave a message. Scammers almost never leave a real message, and if they do, the message itself will contain red flags.

    Never press any button during a robocall

    If you pick up and hear a recorded message telling you to "Press 1 to speak to a representative" or "Press 2 to be removed from our list," do not press anything. Pressing a button does not remove you. It confirms to the scammer that your phone number is active and belongs to a real person, which means your number will be sold to other scammers and you will receive more calls.

    The built-in screening tools on your phone

    Every current iPhone has a feature called Silence Unknown Callers. When it is turned on, calls from numbers not in your contacts, recent calls, or Siri suggestions go directly to voicemail without ringing. You can turn it on under Settings > Phone > Silence Unknown Callers. This will not block known contacts. And you will still get the voicemail if someone leaves one.

    If you have a Google Pixel phone, the built-in Phone app includes a Call Screen feature. When an unknown number calls, Google Assistant answers for you and asks the caller to state their name and reason for calling. You see the transcript on your screen in real time and decide whether to pick up, hang up, or mark as spam.

    Current Samsung Galaxy phones include a call protect feature built into the Samsung Phone app. You can turn it on under Phone app > Settings > Call Protect.

    Free third-party apps

    Several free apps work alongside your phone's built-in features to block more spam calls:

    • **Hiya** (iOS and Android) — identifies spam and scam callers and blocks them. Free version available. Download from the App Store or Google Play.
    • **Nomorobo** (iOS and Android) — blocks robocalls in real time. Free for landlines through VoIP providers. A small fee for mobile phones.
    • **YouMail** (iOS and Android) — replaces your voicemail, blocks spam, and plays a "number disconnected" message to robocallers so they remove your number from their list. Free basic version available.

    Your carrier's built-in spam tools

    Most major US carriers offer their own spam-call protection at no cost:

    • **AT&T** — AT&T Call Protect (free, available in the App Store and Google Play)
    • **T-Mobile** — Scam Shield (free, available in the App Store and Google Play)
    • **Verizon** — Call Filter (free basic version, available in the App Store and Google Play)

    Call your carrier or check their website to activate the free version if it is not already enabled on your account.

    Sign up for the Do Not Call Registry

    The National Do Not Call Registry (donotcall.gov) is run by the FTC. When you register your number, it is illegal for most telemarketers to call you. It will not stop all robocalls — scammers ignore the list — but it cuts down on legal telemarketing calls a lot. Registration is free and only takes a minute. Go to donotcall.gov or call 1-888-382-1222 from the number you want to register.

    Report unwanted calls to the FTC

    If you receive a suspected scam call, report it to the FTC at ReportFraud.ftc.gov or donotcall.gov/report. Your report helps the FTC identify patterns and build cases against the companies making illegal calls. It takes about two minutes and you do not need to provide your name.
