Blocking a number on an iPhone is a fairly straightforward process. It’s easier than most people think and can be done in just a few steps. Not only that but it can also be reversed if you ever change your mind down the line. In this article, we’ll look at everything you need to know about blocking a number on an iPhone including how it works and what happens when you do it. Let’s get started!

How to Block a Number on an iPhone?

If you ever find yourself in the position of needing to block someone’s phone number on your iPhone, it’s straightforward to do. You can either go through your Phone app or the Settings app, and each process only takes a few seconds.

To start blocking a number on your iPhone: 

  • Open the Phone app and tap on “Recents.” 
  • From here, locate the number you’d like to block and tap on the “i” icon. 
  • Next, scroll down and select “Block this Caller.”
  • Confirm that you want to block this contact.

Alternatively, if you want to block multiple numbers at once:

  • Open the Settings app and select “Phone” then “Blocked Contacts.” 
  • Here you can enter all of the numbers that you’d like to block and they’ll all be added to your blocked list at once.

What Happens When You Block a Number on iPhone?

Have you ever been the victim of a nuisance phone call or had an unwelcome conversation that you wished you could just forget? Blocking a number on an iPhone is straightforward but what exactly happens when you do it? Once blocked, the person at the other end cannot reach you via text or call and their messages won’t even appear in your notifications or voicemail. 

However, they will be unaware their calls and texts are being blocked; instead they will simply see that their message ‘has not been delivered’.

The only way for them to know they have been blocked is if they use a third-party app to check if your number is being blocked. As long as this isn’t done, the person at the other end should remain unaware that their attempts to contact you have come up against a brick wall.

When You Block Someone on iPhone, Can They Still Text or Call You?

If you block someone on your iPhone, you may wonder if they can still text or call you. The good news is that no, they cannot. When you block someone from your iPhone, all incoming calls, texts, and FaceTime calls from that person will be blocked. This means the person will not hear a ringtone or receive any notification for incoming messages sent to you because the messages simply won’t be delivered. Additionally, no matter how often the blocked contact tries to call or message you, the calls will never go through to your phone.

How to Tell if Someone Has Blocked Your Number on iPhone?

You may be wondering how to tell if someone has blocked your number on iPhone. There are a few simple signs that can help you determine if you’ve been blocked.

1. Call Them

The most obvious and direct way to find out is by calling the person. A blocked call should go directly to their voicemail, meaning you won’t even hear a ringing before it goes to voicemail. If they don’t answer and the call goes directly to voicemail, it could be a sign that they have blocked your number.

2. Text Messages

Another indicator of a blocked number is when all of your text messages are sent but never receive a response. If your messages seem to be going through but you never get a reply, the recipient may have blocked you.

3. iMessage FaceTime

iMessage and FaceTime are two of the most popular services offered by Apple and if someone has blocked your number from contacting them through these services, you will experience some tell-tale signs. With iMessage, if the message bubble appears blue instead of the green that’s an indication that your message was delivered but not read indicating that the user may have blocked your number from receiving future messages or calls via these services.

What Happens if the Person Already Left a Voicemail?

You might wonder what happens if the blocked person has already left a voicemail on your iPhone. The good news is once you block a number, any voicemails they leave will also be blocked. The voicemail won’t even appear in your Voicemail list so it won’t take up any space on your phone or anything.

For those wondering if it’s possible to see the blocked voicemails or retrieve them later if you change your mind, the answer is sadly no. Once you block someone’s number and they leave a voicemail, that voicemail is gone forever. This means that it’s essential to think carefully before blocking anyone, because that action could mean losing out on important or time-sensitive information.

What to Do if You Accidentally Block a Number on an iPhone?

If you accidentally block a number on an iPhone, don’t fret. You can easily unblock that number later. All you need to do is:

You should also be aware that when you block a number:

  • Incoming calls from this number will appear as missed calls in your call log
  • Text messages from blocked numbers will appear on your phone as blank texts
  • You will not receive notifications for any missed calls or messages from blocked numbers

It’s important to note that blocking a number does not prevent the caller from leaving voicemails meaning they will still be able to leave voicemails. However, these voicemails will no longer appear in your voicemail inbox. Instead, they are redirected directly to an alternative mailbox associated with the blocked number.

Blocking a number also means that you are protecting your privacy rights. It’s estimated that 1 billion scam calls per month are blocked by phone service companies.
