how to block a phone number on Android phonesShutterstock

Keeping in touch with family and friends has become easier and faster thanks to our Android smartphones. However, not all people who can contact us through our mobile phones are people we love and cherish. Some are spammers, annoying strangers, telemarketers, and other unwanted callers. You don’t need to suffer these unwanted calls — go ahead and block them!

In this guide, learn how to block a phone number on your Android smartphone.

How to block a phone number with built-in call blocking features

Most Android phones have a native way to block specific numbers. There didn’t use to be a generalized way to do this, though, so manufacturers often had to build the feature into their own software skins.

This is why the procedure can be unique on your specific device, as it varies from phone to phone. Needless to say, we can’t go into detail about the necessary steps for blocking calls on every single phone out there, but we can give you an idea and show you how it’s done with the most popular devices.

Stock Android

If you want to know how to block a phone number on a stock Android handset like the Google Pixel 3, you’ve come to the right place. There are two ways to do this. The simplest one is to open your Phone app and access the section containing your recent calls. Long press on any of them and select “Block number.”

The second method consists of opening the Phone app, tapping on the three-dot menu icon on the top-right corner, and selecting “Settings.” From the menu, just hit “Call blocking” and add the numbers you want to block.

Some carriers make it easier!

Want to really get rid of those annoying callers? Doing it from your phone works, but what if you switch handsets often? Maybe you want this done in a more systemic way. Some U.S. carriers, including the four major ones (Verizon, AT&T, T-Mobile, and Sprint), allow you to block specific numbers on a service level. Terms and conditions apply — check out exactly what the big four carriers are offering via the links below.

Third-party apps for blocking phone calls

If your Android phone doesn’t have an in-built call-blocking feature or if it does but you find it lacking, you might be wondering how to block a phone number using another method. Thankfully, you can choose one from the many third-party call-blocking apps on the Google Play Store. Of particular note are Mr. Number, Call Blocker, and Calls Blacklist.

Mr. Number

Mr. Number call blocker

Mr. Number is a free and ad-free Android app that allows you to block unwanted calls and texts on your mobile phone. This app protects your phone from spam, allowing you to block calls from people as well as businesses.

You can block calls from individual numbers, an area code, and even an entire country. You can also block private and unknown numbers by sending them straight to voicemail and report spam calls to warn other people using the app. Download it via the link below if you want to give it a try.

Call Blocker

Another handy call blocker app that you’d want to try is the free and ad-supported Call Blocker. If you subscribe to the paid and ad-free version, you can enjoy premium features including Private Space that securely stores private SMS messages and call logs.

Call Blocker pretty much works the same as Mr. Number and other call blocking apps. It will block unwanted and spam calls, and even comes with a Call Reminder feature that helps you identify unknown numbers. There’s also a Whitelist available for storing numbers that can always reach you. Hit the button below to download it to your device.

Calls Blacklist

Calls Blacklist

Last but not the least on our list is the free and ad-supported Calls Blacklist, a very simple app for keeping a list of contacts that you don’t want to allow to contact your phone. An ad-free premium version is also available for about $2.

To block calls with Calls Blacklist, just launch the app and add a contact number to the Blacklist tab. You can add a number via your Contacts, call logs, messages log, or add numbers manually. That’s it — contacts saved under Blacklist won’t be able to call your Android phone anymore.
