Block a number directly from a call or message
The fastest way to block a number on iPhone is to do it the moment you see the call or text. When a call comes in, swipe up from the bottom of the screen (or tap the X on older models), then tap the number or contact name. Scroll down and tap Block this Caller. The person cannot call or text you again, and their messages go to a separate folder you can ignore.
If you get a text from someone you want to block, open the message thread, tap the contact name or number at the top, then scroll down and tap Block Contact. You can also press and hold the message itself, tap More, then tap the prohibition symbol and confirm.
Once you block a number, that person's calls go straight to voicemail, their texts land in a blocked folder, and they will not see a "delivered" notification. They may not realize they are blocked — the call or message straightforward fails to reach you.
Key Takeaways
- You can block a number during an incoming call by swiping up, tapping the number, scrolling down, and selecting Block this Caller.
- Text messages from blocked numbers go to a separate folder in the Messages app that you can view or delete without reading them.
- Blocked callers hear a normal ringtone but their call routes to voicemail, so they may not know they are blocked.
- You can unblock a number at any time by going to Settings, Phone, Blocked Contacts, swiping left on the name, and tapping Unblock.
- Blocking works only on your device — the person can still reach you from a different phone number unless you block that one too.
Block a number from your contacts list
If the number is already saved in your Contacts app, open Contacts, find the person's name, and tap Edit in the top right. Scroll to the bottom and tap Block this Caller, then confirm. This blocks all phone numbers and email addresses linked to that contact at once.
This method is useful if someone has multiple numbers in your phone and you want to block them all together. If you later add a new number for the same person, you will need to block that number separately.
Block a number from your recent calls list
Open the Phone app and tap Recents at the bottom. Find the number or contact you want to block, swipe left on it, and tap the prohibition symbol (or tap the information icon, scroll down, and tap Block this Caller). The number is now blocked.
This route works well if you do not have the number saved as a contact and do not want to save it before blocking.
Block a number from Settings
You can also manage your blocked list directly in Settings. Go to Settings > Phone > Blocked Contacts. Tap Add New and type the phone number or contact name you want to block. Confirm, and the number is blocked when ready.
This method lets you block a number without waiting for a call or message from them. You might use this if someone gives you a number you do not want to hear from, or if you want to block a number before they contact you.
View and manage your blocked list
To see all the numbers you have blocked, go to Settings > Phone > Blocked Contacts. The list shows every number and contact you have blocked on this device. To unblock someone, swipe left on their name and tap Unblock, or tap Edit and tap the minus symbol next to their name.
If you block a contact by mistake, you can unblock them the same way. Unblocking restores their ability to call and text you normally. You can block and unblock the same number as many times as you need.
What happens to blocked calls and messages
When you block a number, calls from that person go straight to voicemail. They do not see a busy signal or a message saying they are blocked — the call straightforward rings once or twice and then goes to voicemail. Text messages from blocked numbers appear in a separate folder in the Messages app labeled Blocked.
You can view your blocked messages folder by opening Messages, tapping Edit in the top left, and looking for the Blocked folder. You can read, delete, or unblock from this folder without the sender knowing. If you delete a blocked message, it is gone permanently.
Blocked callers cannot see that their calls failed — they straightforward hear your voicemail greeting. This means blocking is quiet and does not create conflict or alert the person that you have blocked them.
Block unknown callers and spam
If you want to block calls from numbers not in your contacts, go to Settings > Phone and turn on Silence Unknown Callers. This sends all calls from numbers you do not know directly to voicemail. Your contacts and recent callers still ring through normally.
This is different from blocking specific numbers — it blocks entire categories of calls. You can still see missed calls from unknown numbers in your recent calls list and call them back if you choose. Many people use this feature to reduce spam calls without blocking individual numbers.
Frequently Asked Questions
Can a blocked person still leave me a voicemail?
Yes. Blocked callers can still leave voicemails, but you will not receive a notification. You can listen to their voicemail in the Voicemail tab of the Phone app if you choose, or delete it without listening. They cannot tell whether you heard their message.
What if someone calls me from a different number after I block them?
Blocking works only on the specific number you blocked. If the person calls from a different phone, that call will ring through normally unless you block that number too. You will need to block each number separately.
Does blocking someone on iPhone block them on iMessage too?
Yes. When you block a contact or number, it blocks calls, texts, FaceTime, and iMessage all at once. Messages from that person in any form go to your blocked folder.
Can I block a number without saving it as a contact first?
Yes. You can block a number from your recent calls, from a text message, or by going to Settings and typing the number directly. You do not need to save it as a contact.
If I unblock someone, do they know?
No. Unblocking is silent. The person does not receive a notification that you unblocked them. They can call or text you normally again, but they will not know you had blocked them.
