Smartphones have brought us closer to the people we care about and given us the convenience of instant communication. But not every call or message is welcome. From telemarketers and scam calls to personal conflicts and persistent spam, there are times when you just don’t want to be contacted by certain numbers. Fortunately, Apple makes it incredibly easy to take control of your iPhone and block any number you want.
Whether you’re looking to stop a spammer, protect your child’s device, or simply avoid someone you no longer wish to hear from, this comprehensive guide will show you how to block the number on iPhone, using various built-in methods. No extra apps or complicated steps needed—just a few taps and peace of mind is yours.
Why Block a Number on iPhone?
Blocking a number might sound harsh at first, but it’s a healthy and effective way to create boundaries, protect your privacy, and eliminate unwanted distractions. Here are some common reasons why people block numbers:
- Stop robocalls, spam, and scam attempts
- Avoid unwanted communication from ex-partners, acquaintances, or strangers
- Reduce interruptions during work, meetings, or sleep
- Create a safe digital space for kids using an iPhone
- Prevent harassment or threatening behavior
Blocking a number on an iPhone doesn’t just silence calls—it blocks texts, FaceTime, and even iMessages, making it a complete communication shield.
Method 1: Block a Number Through the Phone App (Recent Calls)
If you’ve recently received a call from a number you’d like to block, the Phone app offers a fast and easy solution.
Steps to Block a Number from Recent Calls:
- Open the Phone app
- Tap the Recents tab at the bottom
- Locate the number you want to block
- Tap the small (i) icon next to the number
- Scroll down and tap Block this Caller
- Confirm by tapping Block Contact
Once blocked, that number will not be able to call, text, or FaceTime you again.
Method 2: Block a Saved Contact from the Contacts App
If the number is saved in your Contacts, you can block it directly from the contact page—no need to wait for a new call or message.
Steps to Block a Contact:
- Open the Contacts app or go to Phone > Contacts
- Find and tap the contact you want to block
- Scroll to the bottom of the contact page
- Tap Block this Caller
- Tap Block Contact to confirm
This will immediately block all calls and messages from the saved contact.
Method 3: Block a Number from the Messages App
Unwanted texts can be just as annoying as calls. The Messages app makes it easy to stop receiving messages from a specific sender.
Steps to Block a Number in Messages:
- Open the Messages app
- Tap the conversation with the number you want to block
- Tap the number or name at the top of the screen
- Tap Info (ℹ️ icon)
- Scroll down and tap Block this Caller
- Tap Block Contact to confirm
After this, you will no longer receive texts or iMessages from that number.
Method 4: Manage Blocked Numbers Through Settings
You can also manually manage your blocked list through the iPhone’s Settings. This is useful for reviewing who you’ve blocked and adding or removing numbers as needed.
How to Access the Block List:
- Open Settings
- Scroll down and tap Phone, Messages, or FaceTime (all three sections have access to the same blocked list)
- Tap Blocked Contacts
From here, you can:
- View all blocked numbers and contacts
- Tap Add New to block additional people
- Swipe left on any number to unblock them
What Happens When You Block a Number on iPhone?
Blocking someone is a powerful action. Here’s what exactly happens when you block a number:
- Calls: The person’s calls will go straight to your voicemail (if enabled), and you won’t receive any ring or notification.
- Messages: Texts and iMessages from that number won’t be delivered to your inbox.
- FaceTime: The blocked person won’t be able to FaceTime you.
- Notifications: You receive no alerts, sounds, or pop-ups from blocked contacts.
- No Notification for the Blocked Party: They won’t be notified that they’ve been blocked.
This means you can maintain privacy without confrontation, while keeping your phone peaceful and focused.
Can You Still See Voicemails from Blocked Numbers?
Yes. Blocked callers can still leave a voicemail—but their message goes into a separate folder called Blocked Messages, which is hidden in the Voicemail tab.
- You won’t receive a notification about the voicemail
- You can listen to it if you want, but it won’t interrupt you
This feature can be helpful in case a blocked caller leaves something important—or proof of harassment, if necessary.
How to Unblock a Number
If you change your mind or mistakenly blocked someone, unblocking them is quick and easy.
Steps to Unblock:
- Go to Settings > Phone > Blocked Contacts
- Tap Edit (top right corner)
- Tap the red minus icon next to the number
- Tap Unblock
Alternatively, go to the contact’s page and tap Unblock this Caller at the bottom.
How to Block Unknown or Private Numbers
Unfortunately, iPhones don’t allow you to block “No Caller ID” or private numbers directly. However, there’s a workaround using the Silence Unknown Callers feature.
Steps to Silence All Unknown Numbers:
- Go to Settings > Phone
- Tap Silence Unknown Callers
- Toggle it ON
With this enabled:
- Calls from numbers not in your Contacts, Messages, or Mail will be silenced
- They will still appear in your Recents tab
- You won’t hear them ring or vibrate
This is perfect for avoiding spam, robocalls, or unknown harassment attempts.
Tip: If you’re waiting for a call from a doctor, job recruiter, or delivery, disable this feature temporarily so you don’t miss it.
Blocking Texts from Email Addresses or iMessage Spam
If you receive spam messages via iMessage from email addresses or unknown IDs:
- Open the message
- Tap the sender’s name or email at the top
- Tap Info > Block this Caller
You can also report spam by tapping Report Junk (available in iMessage for unknown senders).
Does Blocking a Number Remove Past Messages or Calls?
No. Blocking someone only prevents future communication. Their previous messages, call logs, or voicemails will remain on your phone unless you delete them manually.
To keep your inbox clean, you can:
- Delete the conversation in Messages
- Remove call history in the Phone app
- Delete voicemails from the Voicemail tab
How to Leave a Group Chat with a Blocked Number
Blocking someone in a group chat does not remove you from the conversation. You’ll still see their messages within the group.
To fully avoid them:
- Tap the group chat
- Tap the group icon at the top
- Scroll down and tap Leave this Conversation (works only in iMessage groups with 3+ people)
Alternatively, mute the group by turning on Hide Alerts.
Tips to Strengthen Call and Text Blocking
- Use a strong passcode: Prevent children or others from unblocking numbers.
- Enable Screen Time for child accounts: You can control communication limits.
- Update your contact list regularly: So you only silence numbers you truly don’t know.
- Be cautious with your number: Avoid sharing it on suspicious websites or public forums.
- Report persistent spam to your carrier: Many carriers allow you to forward spam messages to a short code (e.g., 7726).

Final Thoughts: Reclaim Control of Your iPhone
Blocking a number on your iPhone is more than a feature—it’s a boundary-setting tool that empowers you to protect your peace, your privacy, and your mental well-being.
