How to Block Nuisance Calls and Messages on Your iPhone

Unsolicited phone calls and messages can become a regular annoyance and even a cause of stress for many smartphone users these days. Thankfully, Apple provides features in iOS 11 that allow you to block nuisance calls and messages from the same number coming through to your phone, and in this article we're going to show you how to set them up.

Whether it's messages from a debt collector looking for the wrong person, a random number from a foreign country that keeps calling in the middle of the night, or just someone in your contacts that you'd rather not hear from again, following the steps below should stop them from bothering you.

How to Block a Recent Caller in iOS 11

If the number you want to block is a recent caller, follow these steps on your iPhone.
  1. Launch the Phone app.
  2. Tap Recents.

  3. Locate the number you want to block in the All or Missed calls list.
  4. Tap the information icon (the encircled lowercase "i") to the right of the number.
  5. Scroll down the Caller ID screen and tap Block this Caller.

How to Block a Number That Messages You

If you're the recipient of unwanted messages from a specific number, here's how to prevent them from coming through to your iPhone.
  1. Launch the Messages app.
  2. Navigate to the main messages list if necessary, and tap a message received from the number you want to block.

  3. Tap the information icon (the encircled lowercase "i") at the upper right of the message window.
  4. At the top of the Details screen, tap the name of the contact or the associated phone number.

  5. Scroll down the Caller ID screen if necessary and tap Block this Caller.

How to Block a Number in FaceTime

If you received a FaceTime call from a number that you want to block, follow these steps.
  1. Launch the FaceTime app.
  2. Tap either the Video or Audio button, depending on the type of FaceTime call you received from the caller you want to block.

  3. Locate the unwanted call you received in the list and tap the information icon (the encircled lowercase "i") next to it.
  4. Scroll down the Caller ID screen if necessary and tap Block this Caller.

How to Manage Blocked Contacts on iPhone

Follow these steps to add or remove a contact from your blocked list of numbers.
  1. Launch the Settings app.
  2. Tap Phone in the list.
  3. Tap Call Blocking & Identification.

  4. To remove a contact from your blocked list, tap Edit in the upper right corner of the screen, tap the red minus button that appears next to the contact(s) you want to remove, and then tap Done.
  5. To add a contact to your blocked list, tap Block Contact... and select the contact from your Contacts list. All of the numbers in the contact card you select will be added to your blocked list.
Note that you can also access and manage your blocked contacts list in the Settings app via Messages -> Blocked and FaceTime -> Blocked.

Try a Third-Party Blocking Solution

If you're inundated with spam calls from different numbers on a regular basis, then consider one of the many third-party blocking solutions available from the App Store: Several apps like Hiya and TrueCaller use an implementation of Apple's CallKit to identify and block suspect numbers before your phone even rings.

After installing one of these apps, you can manage their call permissions at any time from within the Settings app, by tapping Phone and selecting Call Blocking & Information.

What we need is a solution to block “unknown” and “no caller ID” numbers. I realize that people have the right to block their number during a call, but I also have a right to block their unsolicited harassment.

Problem is that some spammers are avoiding this by auto generating numbers, often similar to mine - only the last four digits are random, the first six are the same. Happens to my friends too that they get calls matching their numbers. Guess they try to pretend to be from your neighborhood... well I’m no longer picking those numbers up, still annoying ... but people I care about are in my contacts everyone else can leave a voicemail

Spammer, telemarketing,.... etc suck and they don’t care about the do not call list.

No, Apple. I don’t want a blacklist feature. Considering my blocked callers list has grown into an unwieldly list of numbers that’s hard to sort, manipulate and maintain, I just want a whitelist feature.

If you’re not in my Contacts, I don’t want my iPhone to ring. Period.

We are just too connected in this world. If I can make my Facebook and Twitter accounts private and only allow access by invite, my phone number should work the same way.

What I found is working for me when I receive e-mail spam, ('')is to sign them up to pornographic websites. One idiot was stupid enough to SMS spam his name and phone number to me so I signed him up to a porn site, created a story he was seeking group BBW hookups and contact him on his phone number. I encourage everyone to return the spam favours - they are people too who just need some anonymous love not your money.

I wish there was a more sophisticated system of blocking robo-calls then blocking the onsey-twosey.

I understand there are apps that advertsise to do that, most seem to require a subscription which I'm not about to do.

To temporarily block calls

That’s not going to stop scam calls from using local “Spoofed” numbers that will appear to be legitimate, when in fact they are not. I would really like to see cell carriers implement something in the future that can prohibit scammers from doing this. The Problem is, is scamming is so dynamic that’s changing all the time and once one remedy is issued to stop scam calls, there is another form of a new scam. Its a vicious cycle that never stops unfortunately. The most unfortunate part, is there victims every day who fall for scams.

Wish there was a way to set DND to not require two calls before people on my favorites rang my phone and watch. I too leave my phone on silent all day. Junk calls are probably the worst this year than any year. FCC do not call is a joke. And blocking the random number is a pointless reaction. If the number isn’t in my contacts why the heck isn’t there an option to set it not to ring?

This really has gotten out of hand. The robo calls will call my phone and my wife’s phone at the exact same time. It’s so irritating, made worse, by the fact that you can’t answer and cuss anyone out since it’s a dang computer. Back in the day, I’d answer and blow a whistle into the phone mic. :-) “Sir! Please stop that, it hurting my ears!” Ahhh, that felt GOOD!

Phone companies need to develop a way of detecting a number that has been computer generated. Something like a code that can’t be faked in order for it to be passed along to our phone.

Blocking the number is only good for a day since the number changes the next day. When I’m on call, I HAVE to pick up my phone since I don’t know if a lineman is needing help with something during an emergency.

It’s probably the Russians.

Things like Hiya and Truecaller should be included in your phone service and should work to prevent the calls from ever reaching your phone in the first place. Additionally, carriers should be required to reveal the real phone number that is calling you and not a spoofed number. They obviously know who is calling you because they have to figure out how to bill that number, be it minutes on an unlimited plan or what, but spoofing caller ID should easily be able to be prevented if the phone companies applird a little time to it.

Have you taken the time to read the terms of use for "Hiya" and "Truecaller," ? If not, it would behoove you to do some reading before endorsing either one.

From Hiya's website:

"In the course of using the Services, you may transmit or otherwise make available certain content to us, including information about yourself. Unless otherwise stated in this Agreement or our Privacy Policy (''), by submitting such content, you represent and warrant that: (i) you are at least 18 years old; (ii) you own and control all rights to the content you transmit or otherwise make available, or you have the lawful right to distribute, reproduce, and provide such content; (iii) such content is accurate and not misleading; and (iv) transmitting or providing such content does not: (a) violate this Agreement or (b) violate the rights of, or cause any injury to, any person or entity. Further, you grant us a world-wide, royalty-free, perpetual, irrevocable license to use, reproduce, modify, perform, display, distribute, create derivative works in, store and archive such content. Also, you understand and agree that Hiya retains the right to reformat, excerpt or translate any content provided or transmitted by you.

You also agree that we may collect and use technical information such as your IP address, device ID and other information, including, but not limited to, technical data about your mobile device and system software and peripherals, to facilitate the provision of software updates, product support and other services to you related to the Services.

Any content you provide or transmit will be treated in accordance with our Privacy Policy (''). Any comments or materials sent to us, including, but not limited to, ideas, questions, comments, suggestions, feedback or the like regarding any Services or any other products or services of Hiya (collectively, “Feedback”), is non-confidential and shall become our sole property. We shall have no obligation to you of any kind, monetary or non-monetary, with respect to Feedback and shall be free to reproduce, use, disclose, exhibit, display, transform, create derivative works from and distribute the Feedback to others without limitation or obligation."

"Truecaller is even more shady, in my opinion. They used to post on this forum and got caught in several lies when being questioned about their business model, in regards to collecting (essentially data mining) user information to sell to others.

When You install and use the Services, Truecaller will collect personal information from You and any devices You may use in Your interaction with our Services. This information may include e.g.: geo-location; Your IP address; device ID or unique identifier; device manufacturer and type; device and hardware settings; SIM card usage; applications installed on your device; ID for advertising; ad data, operating system; web browser; operator; IMSI; connection information; screen resolution; usage statistics; default communication applications; access to device address book; device log and event information; logs, keywords and meta data of incoming and outgoing calls and messages; version of the Services You use and other information based on Your interaction with our Services such as how the Services are being accessed (via another service, web site or a search engine); the pages You visit and features you use on the Services; the services and websites You engage with from the Services; content viewed by You, content You have commented on or sent to us and information about the ads You see and/or engage with; the search terms You use; order information and other usage activity and data logged by Truecaller’s servers from time to time.

You know the contact information was likely spoofed too, right? What you probably did was sign up a perfectly innocent person to receive massive amounts of porn. Congratulations.
