In this guide, you’ll learn multiple ways to block a number on Android, including using the Phone app, Contacts app, and third-party solutions for advanced call filtering.

This guide is suitable for all Android users, regardless of device brand or experience level.

How Do You Block a Number on Android?

Android allows you to block numbers directly from your call history, contact list, or messaging apps. The exact menu names may vary slightly depending on your Android version and manufacturer, but the core process remains the same.

What You’ll Need

Before getting started, make sure you have:

• An Android smartphone or tablet
• Access to the Phone or Contacts app
• An updated Android operating system (recommended)

No additional apps are required for basic number blocking.

Method 1: Block a Number Using the Phone App

This is the most common and fastest way to block a number after receiving a call.

Steps:

1. Open the Phone app on your Android device.

2. Go to Call log or Recent calls and Find the number you want to block.

3. Tap the number to open call details, then Tap More options (three-dot menu).

4. Select Block contact.

5. Confirm when prompted.

Once blocked, calls from this number will no longer ring your phone, and the caller may be sent directly to voicemail.

Method 2: Block a Number from the Contacts App

If the number is already saved in your contacts, you can block it directly from there.

Steps:

1. Open the Contacts app.

2. Search for and select the contact you want to block.

3. Tap the contact’s name to open details, then Tap the More options (three-dot menu).

4. Select Block contact.

5. Confirm the action.

Blocked contacts will no longer be able to call or send messages to your device.

Method 3: Block Numbers from the Messages App (SMS)

Many Android devices also allow blocking directly from text messages.

Steps:

1. Open the Messages app.

2. Open the conversation from the number you want to block.

3. Tap the More options (three-dot menu).

4. Select Block or Block & report spam.

5. Confirm your choice.

This is especially useful for stopping spam SMS messages.

Method 4: Use Third-Party Call Blocking Apps

If you receive a high volume of spam or want advanced call identification features, third-party apps can help.

Popular Options Include:

• Truecaller
• Hiya
• Call Control

How to Use Them:

1. Open the Google Play Store.

2. Search for a call blocker app.

3. Install and open the app.

4. Follow the setup instructions and grant necessary permissions.

5. Customize blocking rules, spam filters, and call identification settings.

Note: Third-party apps may require access to call logs and contacts. Review permissions carefully.

Common Issues and How to Fix Them
