How to block text messages on iPhone depends on whether you want to stop one sender, separate messages from unfamiliar numbers, or report suspected spam.
Blocking prevents messages from a specific contact or number from being delivered, while screening only moves unknown messages out of the main conversation list. Reporting spam helps flag suspicious content but does not block the sender automatically.
Choosing the wrong option can leave unwanted texts arriving or hide legitimate verification codes and delivery updates. Follow the methods below to block the right sender, reduce spam without missing important messages, and manage the numbers already on your blocked list.
1. Block vs. Screen vs. Report Spam
These three tools are often confused because they all reduce unwanted messages, but they work in very different ways.
Blocking a number prevents messages, regular call notifications, and FaceTime communications from that blocked number or contact. Messages are not delivered, and the sender is not notified that they were blocked.
A blocked caller may still leave voicemail, but the iPhone does not notify you about it. Blocking one number also does not stop the person from contacting you through a different number or email address. This is the right choice for a person or number that should never be able to contact the iPhone again.
Screening unknown senders does not block anyone. It moves messages from unfamiliar numbers into an Unknown Senders filter so they do not remain in the main conversation list.
Notifications can be allowed for certain categories, including time-sensitive messages such as verification codes. The available notification options vary by country and region
Reporting spam sends information about a suspicious iMessage to Apple. For SMS, MMS, or RCS messages, the report may also be shared with the carrier, depending on the carrier, country, and region.
Reporting deletes the message but does not block the sender. The Report Spam option is available for messages from unknown senders, but it may disappear after you reply.
2. Block a Specific Number or Contact
How to block text messages on iPhone can be done through the Messages app or through the Phone app’s contact settings. The result is the same regardless of which path is used.
Step 1: Open the Conversation in Messages
Open the Messages app and select the conversation from the person or number you want to block.
You can also block a recent caller through the Phone app. Open Recents, select the number or contact, or tap the Info button in Classic view, then scroll down and tap Block Caller
Step 2: Open the Sender’s Information
Tap the sender’s name, number, or icon at the top of the conversation. Tap Info if it appears to open the full contact or sender-details screen.
Step 3: Tap Block This Caller
Scroll down and tap Block Contact or Block Caller, depending on the iOS version and whether the sender is saved in Contacts. Confirm the action when prompted.
Future messages from that blocked number or contact will not be delivered. The sender will not receive a notification that they were blocked, although they may still be able to leave a voicemail.
3. Screening Messages From Unknown Senders
Screening does not block unfamiliar numbers, unlike how to block text messages on iPhone. Instead, it moves their messages into a separate filter, helping keep the main conversation list focused on known senders.
To enable it in iOS 26:
- Open Messages.
- Tap the Filters button at the top of the conversation list.
- Tap Manage Filtering.
- Turn on Screen Unknown Senders.
You can also go to Settings > Apps > Messages and find Screen Unknown Senders under the Unknown Senders options.
To review the filtered conversations, open Messages, tap Filters, and select Unknown Senders. If you recognize someone, open the conversation and tap Mark as Known to move future messages into the primary conversation list.
Messages from unknown senders are generally separated from the main list, but notification behavior can be customized. Depending on the region, you may allow alerts for time-sensitive messages, personal messages, transactions, or promotions.

4. Report and Handle Spam Texts
To report an unopened spam message, swipe left on the conversation, tap Delete, and then tap Delete and Report Spam.
If the conversation is already open, tap Report Spam below the message, then tap Delete and Report Spam. You cannot report it through this option after replying.
Reporting an iMessage sends the message and sender information to Apple. Depending on the carrier and region, reports involving SMS, MMS, or RCS may be shared with the carrier. Reporting alone does not block future messages from that sender.
For suspected scam or phishing texts, a few additional steps of how to block text messages on iPhone can protect against further exposure beyond just blocking or filtering.
- Do not tap links, open unexpected attachments, reply, or provide personal information. Scam texts commonly direct recipients to fake login, payment, or account-verification pages. Delete or report the message instead of interacting with it.
- In the United States, forward the spam text to 7726 (SPAM). The FTC and CTIA recommend this method because it helps wireless providers identify and block similar unwanted messages. Carrier procedures may differ outside the United States.
- Delete the message if it remains after reporting. Apple’s Delete and Report Spam option removes the conversation automatically, so a separate deletion step is usually unnecessary. Avoid replying first because replying can remove the reporting option.
5. View or Manage Your Blocked List
Besides how to block text messages on iPhone, on iOS 26, you can view or manage your blocked list.
Go to Settings > Privacy & Security > Blocked Contacts to review everyone you have blocked. Tap Edit to remove a contact, or swipe left on an entry and tap Unblock. You can also tap Add Blocked Contact to add someone directly from Contacts.
On iOS 18 or earlier, blocked contacts may be managed through the individual Phone, FaceTime, Messages, or Mail settings instead.
Apple’s current system applies contact blocking across supported communication apps, including Messages, Phone, FaceTime, Mail, and Calendar. However, a person may still reach you from a different number or email address that has not been blocked.
6. FAQs
Does Blocking a Number Also Block Their Calls?
Yes. Blocking a number stops its messages and call notifications across Messages, Phone, and FaceTime. The caller can still leave voicemail, but you will not be notified.
Will the Sender Know They Have Been Blocked?
Apple does not notify someone that you blocked them. Their messages are not delivered, although they may infer the block from changes in communication behavior.
Can I Block Texts Without Blocking Calls?
Not with Apple’s standard contact-blocking feature. To silence one text conversation without blocking calls, open the conversation, tap the sender’s name, and turn on Hide Alerts.
What Should I Do if a Blocked Number Still Texts Me?
Messages from the exact blocked number should not be delivered. If new texts appear, check whether they came from another phone number or email address, then block that sender separately.
Conclusion
How to block text messages on iPhone works best when the tool matches the problem. Block a specific number when you want its calls and messages stopped, or enable Screen Unknown Senders when you only want unfamiliar conversations moved out of the main message list.
For suspicious messages, use Delete and Report Spam before replying, then block the sender if you want to prevent future contact. Taking those steps separately ensures the message is reported while also stopping that number from reaching you again.
