You’re sitting at dinner. Your phone buzzes. It’s that one person—the one who doesn’t get the hint, or maybe it’s a "Scam Likely" call about your car’s nonexistent extended warranty. We’ve all been there. Knowing how to block people on an iphone isn't just about technical settings; it’s about reclaiming your digital peace of mind in a world where everyone is reachable 24/7.
It’s surprisingly easy. Yet, most users miss the nuance of what actually happens once you hit that red "Block this Caller" button. Does the message turn green? Do they know? Can they still leave a voicemail? Honestly, Apple’s ecosystem handles these things with a mix of silence and subtle redirection that can be a bit confusing if you don't know the mechanics.
The Basic Nuclear Option: Blocking via Phone and Messages
Let’s start with the most direct route. If someone is blowing up your phone right now, you don't need a degree in computer science to stop it.
Open your Phone app. Tap that little "i" icon next to the number that’s been bothering you. It’s usually blue and sitting right on the right edge of the screen. Scroll all the way to the bottom. You’ll see it: Block this Caller. Tap it. Confirm it. Boom. They’re gone.

But wait. What if they haven't called, but they’re sending annoying texts?
Open the Messages app. Tap the conversation with the person you want to silence. Tap their name or photo at the very top of the screen. Again, look for that "info" button or the "Block this Caller" option. Once you do this, it’s a universal block across the iPhone’s native communication suite. This means Phone, Messages, and FaceTime are all effectively dead zones for that specific contact.
The "Block this Caller" feature is a global toggle. It’s not like the old days of flip phones where you had to call your carrier and pay five bucks a month for a "call screening" service. It's built into the silicon.
What They See (and What They Don't)
This is where the paranoia kicks in. "Will they know I blocked them?"
Strictly speaking, Apple doesn't send a notification saying "Hey, [Your Name] just blocked your annoying hide." That would be a safety nightmare. Instead, the experience for the blocked person is one of purgatory. If they try to call you, the phone will usually ring once and then divert straight to voicemail.
Here is the kicker: they can still leave a voicemail.

I know, it sounds counterintuitive. You’d think a block means a total blackout. But on an iPhone, blocked voicemails are simply moved to a "Blocked Messages" folder at the very bottom of your voicemail list. You won't get a notification. You’ll never see it unless you go looking for it. It’s basically a digital basement where their rants go to die.
For iMessages, things are even more cryptic. The sender will see their message bubble as blue (if they are on an iPhone too), but it will never show a "Delivered" or "Read" status. It just sits there. Forever. To them, it looks like maybe your phone is dead or you’re in the mountains without signal.
Silencing the Unknown: Dealing with Spam
Sometimes it’s not a person you know. It’s the robots. Blocking people on an iphone also extends to those annoying "potential spam" calls that seem to peak right around Tuesday at 10:00 AM.
If you are tired of playing Whac-A-Mole with random digits, there is a better way.
Go to Settings.
Scroll to Phone.
Find Silence Unknown Callers.
Turn that on.
This is a scorched-earth policy. If a number isn't in your contacts, and you haven't recently interacted with them (like a Siri-suggested number from an email), the phone won't even ring. It goes straight to voicemail. It’s a godsend for productivity, though you might miss the occasional call from your doctor or a delivery driver. Use it with caution.

Interestingly, a 2023 report from First Orion suggested that nearly 50% of mobile calls were some form of spam. Apple’s "Silence Unknown Callers" is the primary defense against this trend. It’s better than any third-party app because it’s integrated at the OS level.
The "Hide Alerts" Middle Ground
Sometimes you don't want to block someone. Maybe it’s a group chat with your cousins that gets way too active during football games. Or maybe it’s a coworker who is technically fine but sends too many memes.
You can use Hide Alerts.
Go into the Messages app, swipe left on the conversation, and tap the purple bell icon with a line through it. This keeps the person from buzzing your pocket every thirty seconds, but you’ll still see their messages when you actually open the app. It’s the "polite" way to manage your digital boundaries without the finality of a block.
Managing Your "Burn Book" (The Blocked List)
We’ve all made mistakes. Maybe you blocked someone in a fit of rage three years ago and now you actually need to talk to them. Or maybe you just want to see how many people are currently in your digital "timeout" corner.
- Open Settings.
- Tap Phone (or Messages, or FaceTime—they all lead to the same place).
- Tap Blocked Contacts.
This is your master list. You can swipe left on any number here to unblock them instantly. It’s also a good place to realize that "Pizza Hut" from 2019 is still blocked for some reason.
The Limitation of Email Blocking
If you are trying to block someone who is emailing you through the Mail app, the process is slightly different. You can tap the sender's name in an email and select "Block this Contact."
However, be aware that this doesn't stop the email from reaching your account. It just marks it. Depending on your settings, the Mail app will either leave it in your inbox with a "blocked" icon or move it straight to the Trash. Unlike phone blocking, email blocking is a bit more porous because of how SMTP protocols work compared to cellular handshakes.
Third-Party Apps: Do You Need Them?
You’ve probably seen apps like Hiya, Truecaller, or RoboKiller in the App Store. Are they worth it?
For individual people, no. The built-in iPhone tools are superior.
For massive spam databases, they can be helpful. These apps work by "tagging" numbers as they come in. When a known scammer calls, the app cross-references its database and displays "SCAMMER" on your screen. If you deal with a high volume of business calls and can't afford to "Silence Unknown Callers," these apps act as a filter. Just keep in mind they often want access to your contact list, which is a privacy trade-off you’ll have to weigh.
Actionable Steps for a Cleaner iPhone Experience
To truly master your notifications and boundaries, don't just block and forget. Audit your digital gatekeeping.
- Audit your Blocked List once a year. You might find numbers you don't even recognize anymore.
- Use "Do Not Disturb" for temporary silence. If you're in a meeting, don't block; just use the Focus modes.
- Report Junk. In the Messages app, if you get a text from a number not in your contacts, there’s often a "Report Junk" link under the message. Use it. This helps Apple’s filters get smarter for everyone.
- Check your Voicemail "Blocked Messages" folder. If you are expecting an important call but have "Silence Unknown Callers" on, check there. It’s the most common place for "missing" calls to hide.
Digital boundaries are essential. Your iPhone is a tool for your convenience, not a leash for everyone else's demands. Setting up your block list correctly ensures that when your phone actually rings, it's something you actually want to hear.
