You can block a number directly from your Phone, Messages, or FaceTime apps

iPhone gives you three ways to block someone, depending on where you see their contact. The fastest route is usually to open the app where you last heard from them — Phone, Messages, or FaceTime — find their name or number, and tap the block option. The block takes effect when ready. That person cannot call you, text you, or reach you through FaceTime, and their calls and messages go to a separate folder you can ignore.

If you want to block someone before they contact you, or if you have their number saved in your Contacts app, you can block them from there too. Either way, the steps take less than a minute and do not require restarting your phone.

Key Takeaways

  • You can block a number from the Phone app by tapping the info icon next to their name, scrolling down, and selecting Block This Caller.
  • Messages and FaceTime have their own block options in the conversation details — swipe left on the conversation in Messages, or tap the info icon in FaceTime.
  • Blocked calls and texts still arrive on your phone but go into a hidden folder you can review later if needed.
  • You can unblock someone at any time through Settings > Phone > Blocked Contacts, or by using the same steps you used to block them.

Blocking a number from the Phone app

Open the Phone app and find the number or contact you want to block. This can be someone from your recent calls, your voicemail, or your Contacts list. Tap the info icon — a small circle with an "i" inside — next to their name or number.

Scroll down to the bottom of the screen. You will see a red button that says Block This Caller. Tap it, then confirm by tapping Block Contact in the popup that appears. The block is now active.

Blocking a number from the Messages app

Open Messages and find the conversation with the person you want to block. You can block them in two ways: swipe left on the conversation thread (the way you would delete a message), or open the conversation and tap the contact name or number at the top of the screen.

If you swiped left, a red trash icon appears. Swipe all the way to the left, and more options appear — one of them is Block. Tap it. If you tapped the contact name at the top instead, scroll down and tap Block This Caller, then confirm.

Blocking a number from FaceTime

Open FaceTime and find the person you want to block in your recent calls or contacts. Tap the info icon next to their name. Scroll down and tap Block This Caller, then confirm in the popup.

If you want to block someone before they call you on FaceTime, you can also go to your Contacts app, find their name, tap the info icon, scroll down, and select Block This Caller from there.

Where blocked calls and texts go

When someone you have blocked tries to call you, the call does not ring on your phone. They hear a message saying the call could not go through, though the exact message varies by carrier. Their voicemail, if they leave one, goes to a separate voicemail folder you can access if you need to.

Blocked text messages arrive on your phone but go into a hidden conversation thread. To see them, open Messages, scroll to the top, and look for a Filters option or a section labeled Blocked. The exact location depends on your iOS version, but the messages are always there if you want to review them later.

Unblocking a number

If you change your mind, you can unblock someone at any time. The easiest way is to go to Settings > Phone > Blocked Contacts. You will see a list of everyone you have blocked. Swipe left on the name you want to unblock, and tap Unblock.

You can also unblock someone by reversing the steps you used to block them. Open the Phone, Messages, or FaceTime app, find their name or number, tap the info icon, and look for an Unblock This Caller option instead of the block option.

What blocking does and does not do

Blocking prevents someone from reaching you through the Phone app, Messages, and FaceTime. It does not prevent them from contacting you through other apps like Instagram, WhatsApp, email, or social media. If someone is harassing you across multiple platforms, you may need to block them in those apps separately, or report the behavior to the app itself.

Blocking also does not hide your number from them if they already have it saved. It only stops them from reaching you on your iPhone. If you need to hide your number from someone calling them, that is a different setting in Phone > Settings > Show My Caller ID.

Frequently Asked Questions

Can someone tell if I blocked them?

Not directly from your phone. When they call, they hear a message that the call could not go through, which could mean many things — a network issue, a wrong number, or a block. They cannot see a notification saying "you are blocked." However, if they notice a pattern — calls never go through, but you are active on social media — they may suspect it.

What if I blocked someone by accident?

Go to Settings > Phone > Blocked Contacts, find their name, swipe left, and tap Unblock. You can also unblock them through the Phone, Messages, or FaceTime app by finding their name and tapping the info icon. The unblock takes effect when ready.

Do blocked messages take up storage on my phone?

Yes. Blocked messages still arrive and are stored on your device. If you want to delete them, go to Messages, find the blocked conversation, swipe left, and delete it. This removes the messages from your phone but does not unblock the person.

Can I block a number I do not have saved in my contacts?

Yes. If someone calls or texts you and you do not have them saved, you can still block them. In the Phone app, tap Recent, find the number, tap the info icon, and select Block This Caller. You do not need their name or contact information.

Will blocking someone stop them from seeing my location?

Blocking does not affect location sharing. If you were sharing your location with someone through Find My or another app, blocking them does not stop that sharing. You need to turn off location sharing separately in the app where you set it up.
