The fastest way to block a number on iPhone

Open the Phone app, go to Recents, find the number or contact you want to block, tap the circle with an i next to it, scroll down, and tap Block this Caller. That's it — the number is blocked when ready. You won't receive calls, texts, or FaceTime requests from that number, and they won't know they're blocked.

If you're already in a call with someone you want to block, tap the red end-call button, then go to Recents and follow the same steps. If the number isn't in your Recents yet — for example, you saw it in a text message — you can block it from there instead: open Messages, find the conversation, tap the contact name at the top, scroll down, and tap Block this Caller.

Key Takeaways

  • You can block a number from the Phone app's Recents list, from a text message conversation, or from a contact card in three taps.
  • Blocked callers cannot reach you by phone, text, or FaceTime, and they receive no notification that they are blocked.
  • Blocked numbers still leave voicemails, which go to a separate folder you can delete without listening.
  • You can unblock a number at any time by going to Settings > Phone > Blocked Contacts and swiping left on the name.
  • Blocking works only on your device — the person can still call or text you from a different number.

Blocking from the Phone app

The Phone app is the most direct route if you've already received a call from the number. Open Phone, tap the Recents tab at the bottom, and scroll to find the number or contact name. Tap the circle with an i next to it — this opens the caller's details. Scroll all the way down and tap Block this Caller in red text.

Your iPhone will ask you to confirm. Tap Block Contact and the number is blocked. Any future calls, texts, or FaceTime requests from that number will be silently rejected. The caller will not hear a message saying they're blocked — their call will straightforward ring once and go to voicemail, or their text will appear to send normally on their end.

Blocking from Messages or FaceTime

If you want to block someone based on a text message or FaceTime call instead, you can do it from those apps. In Messages, find the conversation, tap the person's name or number at the top of the thread, and scroll down to find Block this Caller. In FaceTime, swipe left on the recent call and tap the trash icon, then tap Block this Caller from the confirmation menu.

You can also block someone from their contact card. Open Contacts, find the person, tap Edit in the top right, scroll to the bottom, and tap Block this Caller. This method is useful if you want to block someone you know but no longer want to hear from.

Managing your blocked list

To see everyone you've blocked, go to Settings, tap Phone (or Messages or FaceTime, depending on where you blocked them), and scroll down to Blocked Contacts. This list shows all the numbers and contacts you've blocked across all three apps.

To unblock someone, open that same list, find their name, and swipe left on it. A red Unblock button will appear — tap it. The person can then call, text, or FaceTime you again. You can also tap Edit in the top left of the Blocked Contacts list and tap the red minus sign next to any name to unblock them.

What happens to calls and texts from blocked numbers

When you block a number, calls from that number go straight to voicemail without your phone ringing. The caller hears a normal ringing sound on their end, so they may not realize they're blocked — they'll just think you didn't answer. Text messages from blocked numbers still arrive on your device, but they go into a separate conversation thread that you have to manually open to see.

Voicemails from blocked callers go to a separate Blocked Messages folder in the Phone app. You can delete these voicemails without listening to them. To access this folder, open Phone, tap Voicemail, and look for a Blocked Messages tab or section at the bottom. Swipe left on any voicemail and tap Delete to remove it.

Important limits of blocking

Blocking a number works only on your iPhone — it does not block the person from calling or texting you from a different phone number. If someone is harassing you, they can straightforward use another number to reach you. Blocking is effective for stopping unwanted calls from telemarketers, wrong numbers, or people you know, but it's not a complete barrier against determined harassment.

Blocked numbers can still leave voicemails, and those voicemails still count against your voicemail storage. If you're receiving many blocked voicemails, you may want to delete them regularly to free up space. If you're being harassed from multiple numbers, consider reporting the behavior to your carrier or local law enforcement rather than blocking each number individually.

Frequently Asked Questions

Can the person I blocked tell that I blocked them?

No. When a blocked caller tries to reach you, their call goes to voicemail and they hear a normal ringing sound. They have no way to know whether you blocked them, didn't answer, or have your phone turned off. Text messages appear to send normally on their end as well.

What if I block someone by accident?

Go to Settings > Phone > Blocked Contacts, find the name, and swipe left on it. Tap Unblock and they can call or text you again. You can unblock someone at any time — there's no waiting period or confirmation required.

Do blocked voicemails take up storage space?

Yes. Voicemails from blocked numbers still count toward your voicemail storage limit. If you're receiving many blocked voicemails, delete them regularly by opening Phone, tapping Voicemail, finding the Blocked Messages folder, and swiping left to delete each one.

Can I block a number that hasn't called me yet?

Yes. Open Contacts, create a new contact with the number you want to block, save it, then tap Edit and scroll down to Block this Caller. Alternatively, if you have the number in a text message or email, you can copy it, paste it into a contact, and block it that way.

If I block someone, will they see my calls or texts if they try to reach me later?

No. Once blocked, that number cannot reach you by any method on your iPhone. Their calls go to voicemail, their texts go to a separate folder, and their FaceTime requests are rejected. The only way around this is for them to call or text from a different number.
