How to Silence Unknown Callers on an iPhone 13

Even if you are careful about keeping your personal information private, putting your number on the “Do Not Call” list, and generally trying to avoid spam calls, they can still happen.

Unfortunately, there isn’t a perfect way to block calls from spam numbers, telemarketers, or robocalls, but there are steps you can take on your iPhone to make these calls less annoying.

One of these settings will automatically silence calls from unknown numbers.

You can enable the option to silence unknown numbers on your iPhone by going to Settings > Phone > Silence Unknown Callers > then enable Silence Unknown Callers.

Now any number that calls you won’t ring unless you have them saved as a contact, or you have recently made an outgoing call to that number.

Our tutorial below discusses this setting more, as well as some other options for dealing with the unwanted calls that you are receiving on your Apple mobile device.

More Information on Silencing Calls on the iPhone 13

When the “Silence Unknown Callers” setting is turned on, it will do the following:

  • calls from unknown numbers will be silenced, sent to voicemail, and displayed on the Recents list.
  • Incoming calls will continue to ring from people in your contacts, recent outgoing calls, and Siri Suggestions.

The steps above will change a setting for your Phone app so that your phone won’t ring or vibrate if you get a call from a number that’s not in your contacts.

While this doesn’t technically “block” spam or robocalls, it does make them a lot less annoying.

One downfall of this method, however, is if you are expecting a call from someone and they aren’t a contact, as that call won’t ring either.

If you are expecting a call from an unknown number then you may want to go back to Settings > Phone and turn this option off for a bit, or you might want to make a new contact for that number so that it rings.

When silencing unknown callers isn’t enough, then you can also elect to have Do Not Disturb on all the time and only allow notifications from contacts, or another group of people on your phone. you can configure this by going to Settings > Focus > Do Not Disturb.

Alternatively, you could download a third-party app like Robokiller and let it take care of blocking calls for you.
