How to Block a Number on iPhone: Stop Unwanted Calls and Messages

Whether it’s spam, robocalls, or someone you don’t want to hear from anymore, blocking a number on iPhone is fast, easy, and effective. This guide covers how to block numbers on iPhone, how to manage blocked contacts, and what actually happens when you block someone.

How to block a number on iPhone

You can block calls and messages from unknown numbers, saved contacts, or recent callers—all without downloading anything.

Block from the Phone app

If someone just called you:

1. Open the Phone app → tap Recents
2. Tap the (i) icon next to the number
3. Scroll down and select Block Caller
4. Confirm when prompted

The number will no longer be able to call, message, or FaceTime you.

Block from the Messages app

To block someone who sent you a text:

1. Open the Messages app
2. Tap the conversation
3. Tap the contact name or number at the top
4. Tap Info → Block this Caller

Block someone from your Contacts

If the person is saved in your address book:

1. Go to Settings > Phone
2. Tap Blocked Contacts > Add New
3. Choose the contact you want to block

What happens when you block a number on iPhone?

Blocking a number on iPhone completely cuts off communication from that number, and the person isn’t notified.

Here’s what blocking does:

• Calls go straight to voicemail
• iMessages and texts don’t show up at all
• FaceTime calls won’t ring
• Emails (if linked via iCloud) may be blocked as well
• The blocked person sees no notification or alert

You stay invisible—no rings, no texts, no alerts.

How to find blocked numbers on iPhone

If you’ve blocked someone before and want to check your list, it only takes a few taps.

To view your blocked numbers:

1. Open Settings
2. Go to Phone, Messages, or FaceTime
3. Tap Blocked Contacts

You’ll see a complete list of all numbers and contacts you’ve blocked.

How to unblock someone on iPhone

Change your mind? It’s just as easy to undo.

To unblock a contact:

• Go to Settings > Phone > Blocked Contacts
• Swipe left on the name or number
• Tap Unblock

How to block unknown numbers and spam

If spam calls are your main problem, there are additional settings that help reduce unwanted interruptions.

Silence unknown callers

This setting blocks numbers that aren’t saved in your Contacts.

1. Go to Settings > Phone
2. Tap Silence Unknown Callers
3. Turn it on

Filter unknown senders in Messages

This doesn’t block texts but hides them in a separate list.

1. Go to Settings > Messages
2. Toggle on Filter Unknown Senders

Useful if your Messages inbox is overwhelmed by codes, promotions, or unknown numbers.

Can blocked numbers leave voicemails?

Yes—but you won’t get notified. Voicemails from blocked numbers are stored in a separate Blocked Messages section under Voicemail in the Phone app.

Blocked numbers can’t text, call, or FaceTime you, but they can still technically leave a voicemail in this hidden area.

Take control of your iPhone communication

Blocking numbers is one of the simplest ways to reduce digital noise and take back your time. Whether it’s unwanted calls, spam texts, or someone you’d rather not talk to, your iPhone gives you the tools to shut it down instantly.

And if you’re looking to organize your digital life further—like cleaning up contacts, managing voicemails, or backing up your data—tools like WALTR PRO can help you manage your iPhone without iTunes or iCloud.
