Learn How to Block Phone Numbers on iPhone

Understanding iPhone Call Blocking Features

Apple's iPhone operating system includes built-in tools that let you block unwanted phone calls and text messages without needing additional software or services. These features have been part of iOS since 2014 and work across all iPhone models running recent versions of the operating system. When you block a number, that caller cannot reach you through calls, text messages, or FaceTime requests. The blocked person won't receive a notification that they've been blocked, but their call will go directly to voicemail, and text messages won't deliver.

The blocking system operates at the device level, meaning the restrictions apply only to your specific iPhone. If someone calls from a blocked number, you won't hear a ring or see their name appear on your screen. Text messages from blocked contacts won't show up in your conversations. However, blocked callers can still leave voicemail messages, though you won't receive notifications about these messages. This distinction matters because some people use blocking specifically to stop seeing notifications while still preserving a record of attempts to contact them.

iPhone blocking works differently depending on how you initiate it. You can block numbers directly from the Phone app, Messages app, FaceTime app, or from your Contacts list. Each method stores the blocked number in the same unified list, so blocking someone in one app prevents them from contacting you through any method. You can view your complete list of blocked contacts in the Settings app under Phone, Messages, or FaceTime, depending on which app you used to create the block.

Understanding these mechanics helps you decide which blocking method suits your situation. For example, if you're receiving unwanted calls from a business, blocking through the Phone app makes sense. If someone is texting you repeatedly, blocking through Messages keeps conversations clean. The end result is the same—the person cannot contact you—but starting from the relevant app streamlines the process.

Practical Takeaway: iPhone's native blocking system prevents calls, texts, and FaceTime requests from reaching you without notifying the blocked person. The blocked number appears in a unified list, and blocking through any app prevents contact through all methods.

Blocking Numbers Using the Phone App

The Phone app provides the most straightforward method for blocking numbers, especially if you've received unwanted calls. To block a number from the Phone app, open the app and navigate to the Recents tab at the bottom of your screen. This shows your call history, including incoming, outgoing, and missed calls. Find the number you want to block in this list and tap the information icon (the small "i" in a circle) next to the caller's name or number. A details screen appears showing information about that call.

On the details screen, scroll down to find a button labeled "Block this Caller." Tap this button, and a confirmation prompt appears asking if you want to block the contact and report it as spam. You can choose to block the number without reporting it, or select both options. Reporting spam helps Apple's systems identify problematic numbers and can contribute to blocking them for other users. After you confirm, the number is added to your blocked list. You'll see a notification saying the contact has been blocked.

If you want to block a number that isn't in your recent calls—perhaps someone gave you a number to avoid—you can add them to your Contacts first and then block them. Go to the Contacts app, create a new contact with the number you want to block, and save it. Then go back to that contact and tap the information icon. Scroll down and tap "Block this Caller." This method works well when you receive a warning about a specific number from a friend or family member.

Another approach involves blocking directly from voicemail. If someone leaves a voicemail from an unwanted number, open the Voicemail tab in the Phone app, select the message you want to block, and tap the information icon. Choose "Block this Caller" from the menu. This prevents future calls and voicemails from that number.

Practical Takeaway: To block a number in the Phone app, find it in your Recents or Voicemail, tap the information icon, and select "Block this Caller." You can report the number as spam at the same time, which helps protect other users.

Blocking Numbers in Messages and FaceTime

If someone is sending you unwanted text messages or iMessages, blocking through the Messages app provides a direct solution. Open the Messages app and find the conversation with the person you want to block. Press and hold on the conversation thread (don't open it—just long-press the entry in your messages list). A menu appears with several options. Select "Block this Caller" or "Block Contact" from the menu. Confirm your choice when prompted. After blocking, that person's text messages, iMessages, and media won't appear in your Messages app.

You can also block from inside an active conversation. Open a message thread from someone you want to block, then tap their name at the top of the conversation. This opens their contact card. Tap "Info" and scroll down to find "Block this Contact." Confirm your choice, and the person is added to your blocked list. Their previous messages remain visible in the conversation thread, but no new messages from them will arrive.

For FaceTime calls and requests, open the FaceTime app and find the call you want to block in your recent calls list. Tap the information icon next to the caller's name, and select "Block this Caller." This prevents them from sending you FaceTime requests or making FaceTime audio calls. Blocking in FaceTime also blocks them from contacting you through regular phone calls and text messages.

A useful feature across all three apps is the ability to block people you haven't communicated with yet. If someone sends you a message or FaceTime request from an unknown number, you can block them without having previous contact history. Open their message or request and tap the information icon. Choose the block option that appears. This works whether the contact is in your phone's address book or not.

Keep in mind that blocking in Messages or FaceTime also adds them to your phone's unified blocked list. You don't need to block the same person in multiple apps—blocking once prevents contact through all methods.

Practical Takeaway: Block unwanted messengers by finding them in the Messages or FaceTime app, tapping the information icon, and selecting "Block this Contact." Blocking prevents messages and calls through all methods on your phone.

Managing Your Blocked Contacts List

You can view all your blocked contacts in one place by going to the Settings app. The location depends on which app you're checking. For blocked phone calls, open Settings, tap "Phone," and scroll down to find "Blocked Contacts." This list shows every number you've blocked through the Phone app or any other method that affects phone calls. For text messages, go to Settings, tap "Messages," and select "Blocked Contacts." For FaceTime, go to Settings, tap "FaceTime," and find "Blocked Contacts." These separate lists help you organize blocks by communication type, though blocking in any app typically affects all methods.

To unblock a contact, navigate to the relevant blocked list in Settings and find the person you want to unblock. Swipe left on their name (on the iPhone) to reveal the "Unblock" button, or tap "Edit" at the top of the list and then tap the red minus sign next to their name. Confirm your choice by tapping "Unblock." After you unblock someone, they can call, text, or FaceTime you again, and you'll receive notifications of their attempts to reach you.

You might want to manage your blocked list periodically, especially if you've blocked numbers during a period of unwanted contact that has since stopped. For example, if you blocked a number from a telemarketer, business, or service, you may want to unblock it later if your situation changes. Or if you blocked someone during a conflict, you might unblock them once enough time has passed. There's no limit to how many contacts you can block, so don't worry about the list becoming too large.

If you want to see information about a blocked contact before unblocking them, you can also manage blocks through the Contacts app. Open Contacts, search for the person's name, tap "Edit," scroll down, and you'll see a "Block this Contact" toggle that shows whether they're currently blocked. Tap the toggle to change their status. This method is useful if you've forgotten why you blocked someone and want to confirm before unblocking.
