How to Block Robocalls and Spam Calls (2023)

Are you sick and tired of all the spam calls you get? The FCC has tried to crack down on such calls, while lawmakers on the federal and state levels have passed legislation to address the problem. But there are certain actions you can take on your own. Android devices and iPhones come with built-in features for blocking specific phone numbers, while mobile carriers offer their own blocking tools.

Several third-party apps—including Hiya, RoboKiller, Truecaller, and Call Control—also work to block telemarketing calls. And you can register your phone number with the FTC's Do Not Call Registry, though that won't stop scammers and disreputable telemarketers from calling you. Let's check out each option.

(If you’re also receiving unwanted robotexts, there are steps you can take to block them, too.)

Block Numbers on an iPhone

How to Block Robocalls and Spam Calls (1)

Robocallers cycle through thousands of phone numbers, and many include the same telephone prefixes as your own phone number. To block them as they come in on your iPhone, open the Phone app and tap Recents. Tap the Info icon next to the number you want to block and choose Block this Caller and then Block Contact.

The number is now blocked. However, spammers have a habit of jumping from one number to another, so this remedy helps only if the caller uses the same number more than once.

With iOS 13 or higher installed on your iPhone, you can take a more effective but drastic measure to clamp down on spam calls. Go to Settings > Phone > Silence Unknown Callers and turn on the switch for Silence Unknown Callers.

This feature automatically silences all calls from numbers that are not in your contacts list. Calls are sent to voicemail and appear on your Recents lists so you can return the call if it's legitimate.
