Where to find the block list on your iPhone

The block list lives in the Phone app, not in Settings. Open Phone, tap the Contacts tab at the bottom, then tap the info icon (a circle with an "i") in the top right corner. Scroll down and you'll see "Blocked Contacts" — this is where every number you've blocked appears. If you haven't blocked anyone yet, this section will be empty.

You can also reach your blocked list through Settings. Go to Settings > Phone > Blocked Contacts. Both routes show the same list, so use whichever is closer to what you're doing at the moment.

Key Takeaways

  • You block a number directly from a call, text, or contact card by tapping the info icon and selecting "Block this Caller."
  • Blocked numbers cannot call or text you, and their calls go straight to voicemail without your phone ringing.
  • You can see all blocked numbers in Phone > Contacts > info icon > Blocked Contacts, or in Settings > Phone > Blocked Contacts.
  • Unblocking a number is as straightforward as finding it in your blocked list and tapping "Unblock."
  • Blocking someone does not delete their messages or calls that arrived before you blocked them.

How to block a number from a recent call or text

The fastest way to block someone is right after they call or text you. Open the Phone app, find the recent call, and tap the info icon (the circle with an "i") next to their name or number. Scroll down and tap "Block this Caller." A confirmation message appears — tap "Block Contact" to confirm.

The same method works for text messages. Open Messages, find the conversation, swipe left on it, tap the three dots that appear, then tap "Block." You'll see a confirmation screen asking you to confirm the block.

Once blocked, that number cannot reach you by call or text. Their calls roll straight to voicemail, and they won't see a "delivered" status on their texts — they'll just disappear from your phone.

How to block a number from your contacts

If the person is already in your contacts, you can block them from their contact card. Open Contacts, find the person, tap "Edit" in the top right, scroll all the way down, and tap "Block this Caller." Confirm the block when prompted.

This method is useful when you want to block someone you know but don't want to delete their contact information. Their name and number stay in your contacts — they're just blocked from reaching you.

How to block an unknown or spam number

If a number calls or texts you and you don't recognize it, you can block it without adding it to your contacts. After the call or text arrives, tap the info icon next to the number and select "Block this Caller." You don't need to know who they are or save them first.

Many spam calls come from numbers that change with each call, so blocking one number may not stop the calls entirely. If spam is persistent, consider enabling "Silence Unknown Callers" in Settings > Phone. This sends calls from numbers not in your contacts, mail, or messages straight to voicemail, but it also silences legitimate calls from people you don't know.

How to unblock a number

If you change your mind about blocking someone, go to Settings > Phone > Blocked Contacts. Find the number you want to unblock, swipe left on it, and tap "Unblock." The number is when ready unblocked and can call or text you again.

Unblocking does not restore old messages or calls from before you blocked them — those are gone. But going forward, new calls and texts from that number will come through normally.

What happens when you block someone

When you block a number, the person cannot call you, text you, or reach you through FaceTime. Their calls go straight to voicemail without your phone ringing or showing a notification. Their texts disappear — they won't see a "delivered" status, and you won't see the messages arrive.

The blocked person may eventually realize they're blocked if they try to call and always reach voicemail, or if they notice their texts never show "delivered." However, iPhone does not send them a notification saying they've been blocked.

Blocking is one-way. If you block someone, you can still call or text them, but they cannot reach you. This is different from blocking on social media, where both people lose access to each other.

Managing your blocked list over time

Your blocked list can grow quickly if you block spam numbers regularly. Check it occasionally to make sure you haven't blocked someone by mistake. Go to Settings > Phone > Blocked Contacts and review the list — if you see a number you recognize and want to unblock, swipe left and tap "Unblock."

If you're blocking a lot of spam, consider reporting the numbers to your carrier. Most carriers have a way to report spam through their apps or websites, which helps them identify patterns and block spam at the network level before it reaches your phone.

Frequently Asked Questions

Can a blocked person tell they've been blocked?

Not officially — iPhone doesn't send a notification. But if they call repeatedly and always reach voicemail, or if their texts never show "delivered," they may figure it out. There's no way for them to know for certain from your phone.

What if I block someone by mistake?

Go to Settings > Phone > Blocked Contacts, find the number, swipe left, and tap "Unblock." They can call and text you again when ready. Old messages from before the block won't reappear, but new ones will come through.

Does blocking delete old messages from that person?

No. Blocking stops new calls and texts, but it doesn't erase conversations that already happened. If you want to delete old messages, you have to do that separately in the Messages app.

Can I block a number without saving it to my contacts?

Yes. After a call or text from an unknown number, tap the info icon and select "Block this Caller." You don't need to add them to your contacts first.

Will a blocked person's calls go to my voicemail?

Yes. Their calls ring on their end but go straight to your voicemail without your phone ringing or notifying you. You can listen to the voicemail later if you want.
