The fastest way to block a number on iPhone

Open the Phone app, find the number you want to block in your recent calls list, tap the i icon next to it, scroll down, and tap Block this Caller. That's it — the number is blocked when ready. If you don't see the number in recents, go to Contacts, find the person, tap the i icon, scroll to the bottom, and tap Block this Caller.

Blocked callers can still leave voicemails, but you won't see missed call notifications from them. Their calls go straight to voicemail, and their texts won't show up in your message threads — they'll land in a separate folder you have to look for.

You can also block someone from a text message: open the conversation, tap the contact name at the top, tap info, scroll down, and choose Block this Caller. The steps are the same whether the person is in your contacts or not.

Key Takeaways

  • Blocked callers go straight to voicemail and you won't get notifications when they call, but they can still leave messages you can retrieve later.
  • You can block a number from your recent calls, your contacts list, or directly from a text message in three taps or fewer.
  • Blocking is not the same as silencing — a silenced contact can still call through if they call repeatedly in a short time.
  • Your blocked list lives in Settings under Phone, and you can unblock anyone at any time.

Where to find your blocked list and unblock someone

Go to Settings, tap Phone, then tap Blocked Contacts. You'll see everyone you've blocked. To unblock someone, swipe left on their name and tap Unblock, or tap Edit in the top left and tap the red minus sign next to their name.

Unblocking someone when ready restores their ability to call and text you normally. They won't know they were blocked, and unblocking them doesn't send any notification.

The difference between blocking and silencing a contact

Blocking stops calls and texts from reaching you at all (except voicemail). Silencing a contact is different — their calls and texts still come through, but they don't make your phone ring or light up. You'll see them in your message threads and call history, just without the interruption.

To silence a contact, open the Phone app, find their name in Favorites or Recents, tap the i icon, and toggle Silence Notifications on. For texts, open the conversation, tap the contact name at the top, tap info, and toggle Hide Alerts.

There's one exception: if a silenced contact calls you repeatedly within three minutes, their call will ring through anyway. This is a safety feature so people can reach you in emergencies even if you've silenced them.

Blocking unknown numbers and spam calls

If a call comes from a number not in your contacts, you can block it the same way — tap the i icon next to it in recents and choose Block this Caller. But for spam and robocalls, your iPhone has built-in filters you should turn on first.

Go to Settings, tap Phone, then tap Call Filtering. Turn on Filter Unknown Callers to send calls from numbers not in your contacts to voicemail automatically. This catches most spam, though some legitimate callers (banks, doctors' offices) may also be filtered.

If you want more aggressive filtering, some carriers offer their own spam-blocking tools. AT&T has Call Protect, Verizon has Call Filter, and T-Mobile has Scam Shield — check your carrier's website to see what's available and whether it costs extra.

What happens when you block someone on iMessage

Blocking someone through the Phone app blocks both calls and texts. But if you only want to block their iMessages (the blue text bubbles), you can do that separately. Open the conversation, tap the contact name at the top, tap info, and toggle Block this Caller.

When you block someone on iMessage, they can still send you regular SMS texts (green bubbles), but their iMessages won't come through. If you block them in the Phone app instead, both iMessages and SMS texts are blocked.

Blocking contacts on FaceTime

To block someone from calling you on FaceTime, open the FaceTime app, find their name in your recent calls, swipe left, and tap the trash icon. Then tap Block this Caller. You can also block them from the Phone app — blocking there blocks FaceTime calls too.

If someone tries to FaceTime you after you've blocked them, they'll see a message saying the call failed, but they won't know you blocked them specifically.

Frequently Asked Questions

Will someone know I blocked them?

No. Blocked callers won't get a notification or message saying they're blocked. Their calls go to voicemail and their texts disappear from your threads, but they have no way to know for certain unless they try calling from a different number or ask someone else.

Can I block someone and still see their voicemails?

Yes. Blocked callers can still leave voicemails, and you can listen to them whenever you want. Go to the Phone app, tap Voicemail, and you'll see their messages. You just won't get a notification when they call.

What if I block someone by accident?

Go to Settings, tap Phone, tap Blocked Contacts, find their name, swipe left, and tap Unblock. They can call and text you normally again right away.

Does blocking work across all my Apple devices?

Blocking syncs across your iPhone, iPad, and Mac if you use the same Apple ID and have iCloud Contacts turned on. But blocking on one device doesn't automatically block on others — you may need to block the same number on each device separately depending on your settings.

Can I block calls from a specific area code or number pattern?

Not natively on iPhone. You can only block individual numbers or contacts. If you're getting many calls from the same area code, turning on Filter Unknown Callers in Settings > Phone > Call Filtering will send most of them to voicemail.
