How To Block Texts From Unknown Numbers

Have you ever gotten a text from an unknown number or someone not on your contact list? In today’s world, telemarketers and scammers have used text messages as their preferred marketing technique. These unwanted text messages are not only annoying, but they could be coming from someone whose intentions aren’t exactly pure.

If you want to protect yourself from texts from unknown numbers, an easy solution is to block them. Blocking unknown numbers will only allow you to receive texts from senders who aren’t hiding their phone numbers or company name.

In this article, we’ll show you how to do so from various devices.

Block Texts From Unknown Numbers on an iPhone

There’s a way to block texts from unknown numbers on an iPhone. Unfortunately, there’s no way to do so before an unknown number has texted you. Texts from unknown numbers will be able to text you once, but after following the steps below, they won’t be able to text you again. To learn how to do so, follow the steps below:

1. Open the Messages app on your iPhone.
   
2. Tap on the text you’d like to block.
   
3. On the top of the screen, tap the round icon.
   
4. Just under the round icon, tap the icon for “Info.”
   
5. Tap “Block This Caller.” If you don’t see this option, tap the right-facing arrow on the upper-right part of the screen.
   
6. Select “Block this Caller” and then “Block Contact” to confirm your selection.
   

You can do something else to avoid unnecessary notifications when receiving a text message from an unknown caller. This method doesn’t block the text, but it will stop you from being alerted to it. The message will immediately be routed into a special folder where you can view the message later, and you won’t be notified that you received a text.

If this interests you, follow the steps below:

1. Tap “Settings” and then select “Messages.”
   
2. Scroll down and find “Filter Unknown Senders.”
   
3. Turn the toggle button to the “on” position by tapping on it.
   

Texts from unknown numbers will now be sent to a particular folder where you can view them and decide if you want to block them or not. This feature works similarly to a spam folder used in email apps.

Block Texts From Unknown Numbers on an Android Device

Again, you can block texts from unknown numbers, but only after they have messaged you at least one time. With that being said, you can block them from texting you a second time. To do so, here are the steps:

1. Open the Messages app on your Android.
   
2. Select the text you’d like to block and tap on the “3-dots” icon in the upper right-hand corner of the screen.
   
3. Tap “Details” from the drop-down menu.
   
4. Select “Block and Report Spam.”
   

This unknown number won’t be able to text you again.

Block Texts From Unknown Numbers in Viber

1. Open the Viber app.
   
2. Go to your messages and tap on “Chats.”
   
3. Select the chat you’d like to block.

Additional FAQs

How do telemarketers get my number and then send me unwanted text messages?

Telemarketers, and sometimes even scammers, usually get your phone number by purchasing lists of phone numbers from third-party data providers. These companies gather phone numbers from a variety of different resources.

Legitimate companies compile lists of phone numbers, usually from customers who have provided it on an application, online form, or even from a simple phone call to an 800 number. Unfortunately, sometimes these companies sell these phone lists.

Can they still call me if I block a phone number from texting me?

Yes, but with limitations. Once you’ve blocked a certain number from texting you, the block will follow over to regular phone calls. They will be able to call you; however, your phone will send their call directly to voicemail. Your phone will never ring from a number you’ve blocked from texting.

The same goes for their texts. They can text you, but their texts will never be delivered.

If I block a phone number, will they know that I’ve done so?

The blocked person will never get a message saying that you have blocked them from sending text messages. They’ll never know directly, but if delivery notifications are turned on, they will see that their texts haven’t been delivered. This could be a clue to them that you did block them. However, if they do not use this feature, they won’t have any idea if their text message was delivered or not.

They Can Text You Once, but They Can’t Text You Twice

Blocking unwanted texts from unknown numbers saves you from the hassle of dealing with telemarketers, robotexters, and other text messages that you don’t want to receive. No longer will you get a text notification only to see it’s not from a friend; it’s from someone who’s blocking their phone number. As you learned from this article, you can stop them from harassing you.
