How Do I Block a Number on My iPhone?

Getting unwanted phone calls? Learn how to block them on your iPhone.

Our phones and devices are as important to our lives as clothes and meals. (You try to get through an afternoon without posting to Facebook or snapping a photo of what you had for lunch!) That makes it all the more important to prevent people you’d rather avoid—be they telemarketers or frenemies—from calling or texting and ruining your day.

Fortunately, iOS makes it simple enough to block numbers you don’t know and those you do (but wish you didn’t).

How to Block a Contact

For contacts you’d rather avoid, open your Contacts, tap a name, then scroll to the bottom of the screen and tap Block this Caller. You’ll get a warning prompt in case you’re having second thoughts. If you aren’t, tap Block Contact and — poof! — no more calls, messages, or FaceTime with that person.

While we’re on the topic of contacts: If you’re at the point that you want to block a contact, you might consider erasing that person’s info from your phone. You know, just to make sure you never hear from that person again.

But if you think you might settle your differences (here’s hoping!), then by all means keep the contact’s info. You can always unblock the number by going back to the contact, scrolling to the bottom of the screen, and tapping Unblock this Caller.

How to Block Someone Who Isn’t a Contact

Despite our best efforts to stay of robocall lists, we can still get inundated with spammy disruptions. If you see a number calling over and over again and you want to shut that down:

  1. Tap the number on your call history.
  2. Scroll to the bottom of the screen.
  3. Tap Block Contact. That number can’t bother you any longer.

(If you ever want or need to unlock the number, go back to the contact, scroll to the bottom of the screen, and tap Unblock this Caller.)

How to Block Calls From Unknown Numbers

The third type of call we all get is one that comes up No Caller ID, Restricted, or Unknown. Not only are they a nuisance, but if they’re a telemarketer chances are they won’t leave a message and you’ll never know who it is.

As much as we’d love to banish these calls from our phones, Apple unfortunately doesn’t currently have an option to block them from reaching you. (Because there’s no number being detected by the phone, there’s nothing for the phone to block.)

That said, you can opt-in to the Federal Trade Commission’s National Do Not Call Registry. This won’t take care of all those unknown calls, but it will but a stop to many of them. Learn more about the program and how to add your number on the FTC’s website.
