The fastest way to block a number on iPhone
Open the Phone app, go to Recents, find the number you want to block, tap the info icon (the small circle with an "i"), scroll down, and tap Block this Caller. That number can no longer call or text you, and their calls go straight to voicemail without ringing your phone.
If you do not see the number in Recents, you can block it directly from a text message: open Messages, find the conversation, tap the contact name at the top, tap the info icon, scroll down, and tap Block this Caller. The process is the same whether the unwanted contact is a person or a business.
Once you block a number, you will not see missed calls, voicemails, or text messages from that caller. They will not know they are blocked — their calls straightforward fail to reach you, and they may assume your phone is off or you are not answering.
Key Takeaways
- You can block a number in seconds from the Phone or Messages app by tapping the info icon and selecting Block this Caller.
- Blocked callers cannot reach you by phone or text, and their calls go to voicemail without your phone ringing.
- You can see a list of all blocked numbers in Settings under Phone, and unblock any of them at any time.
- Blocking a number on your iPhone does not stop them from leaving voicemails, though you will not be notified when they do.
- If a blocked number calls from a different number, that new number will ring through normally unless you block it separately.
Blocking from the Phone app
The Phone app is the quickest route if you have already received a call from the number. Tap the Recents tab at the bottom of the screen to see all incoming and outgoing calls. Find the number you want to block in the list, then tap the small info icon (a circle with an "i") on the right side of that entry.
A details screen will open showing the phone number, any name associated with it, and options below. Scroll down until you see Block this Caller in red text, then tap it. A confirmation message will appear asking if you are sure — tap Block Contact to confirm. The number is now blocked.
If the same number appears multiple times in your Recents list, you only need to block it once. Blocking the number stops all future calls and texts from that caller, regardless of how many times they tried to reach you before.
Blocking from the Messages app
If you received a text from the number instead of a call, open Messages and find the conversation with that sender. Tap the contact name or number at the very top of the conversation thread — this opens a details panel on the right side of the screen.
In that panel, tap the info icon (circle with an "i") in the top right corner. Scroll down to find Block this Caller in red text and tap it. Confirm when prompted. The conversation will remain in your Messages app, but you will not receive any new messages from that number.
Viewing and managing your blocked list
To see all the numbers you have blocked, open Settings, tap Phone, then scroll down and tap Blocked Contacts. This list shows every number you have blocked on your iPhone. If you want to unblock a number, swipe left on it and tap Unblock, or tap Edit in the top left corner to select multiple numbers at once.
Unblocking a number removes it from your blocked list, but it does not delete any previous conversations or voicemails from that caller. Once unblocked, that number can call and text you normally again.
What happens when you block a number
When you block a number on iPhone, that caller cannot reach you by phone call or text message. Their calls go directly to voicemail, and your phone does not ring or show a notification. They will not see a message saying they are blocked — the call straightforward fails to connect, which may make them think your phone is off or you are not answering.
Blocked callers can still leave voicemails, but you will not receive a notification when they do. You can listen to those voicemails if you choose to, but they will not appear in your voicemail inbox with a badge notification. If you want to prevent blocked callers from leaving voicemails entirely, you will need to use a different method, such as a carrier-level block through your phone provider.
Blocking numbers from different sources
You can also block a number before you ever receive a call from it. Open Contacts, find the person you want to block, tap their name to open their details, tap the info icon, scroll down, and tap Block this Caller. This prevents them from calling or texting you going forward.
If someone calls you from a number that is not in your contacts, you can block it directly from the incoming call screen. When the call comes in, tap Decline, then tap the info icon that appears, and select Block this Caller. You do not have to answer the call to block the number.
Important limits of iPhone blocking
Blocking a number on your iPhone only works on that specific device. If you have an iPad or Mac, those devices will not automatically block the same number — you will need to block it separately on each device if you want the same protection everywhere.
If a blocked caller uses a different phone number to reach you, that new number will ring through normally. Blocking is tied to the specific phone number, not to the person, so someone determined to contact you can do so from a different line. If you receive calls from multiple numbers from the same source, you will need to block each number individually.
Frequently Asked Questions
Can a blocked number tell they are blocked?
No. When a blocked number tries to call you, they hear a normal ringing sound or are sent to voicemail, just as if your phone were off. They have no way to know for certain that you blocked them — they may assume you are not answering or your phone is unavailable.
Can I block a number without adding it to my contacts?
Yes. You do not need to save a number to your contacts to block it. You can block any number directly from your call history, text messages, or even from an incoming call screen without ever creating a contact for that person.
What if I accidentally block someone I want to hear from?
Open Settings, tap Phone, tap Blocked Contacts, find the number you want to unblock, swipe left, and tap Unblock. Once unblocked, that person can call and text you normally again. Any previous messages or voicemails from them will still be in your history.
Will blocking a number stop them from seeing my location or status?
Blocking prevents calls and texts, but does not affect location sharing or messaging app status. If you shared your location with someone before blocking them, you may need to turn off location sharing separately in your privacy settings or in the Maps app.
Can I block a number through my phone carrier instead of my iPhone?
Yes. Your carrier (AT&T, Verizon, T-Mobile, etc.) offers its own blocking service, which stops calls before they reach your phone and can prevent blocked numbers from leaving voicemails. Contact your carrier to learn about their blocking options, which may cost extra or be included in your plan.
