Android has a built-in block feature that stops calls and texts from specific numbers

You can block text messages on Android directly through your default messaging app or through your phone's system settings. The blocked person can still send you messages, but you won't see them — they go to a separate folder you can check anytime. The process takes less than a minute and works whether you're blocking a single number or multiple contacts.

The exact steps depend on which messaging app you use and which version of Android you have, but the core method is the same across most phones. If you're using Google Messages (the default on most newer Android phones), Samsung Messages, or another third-party app, the blocking option is usually in the conversation itself or in the contact details.

Key Takeaways

  • You can block a number directly from a text conversation by opening the message thread, tapping the menu, and selecting block or report spam.
  • Blocked messages are hidden from your inbox but stored in a separate folder you can view anytime if you change your mind.
  • Blocking through your phone's system settings (Settings > Apps > Messages > Notifications) stops notifications but may not hide the messages themselves.
  • If you block someone and later want to unblock them, you can reverse it through the same menu where you blocked them.
  • Some carriers offer additional blocking tools through their own apps, but the built-in Android method works without paying extra.

Block a number using Google Messages

Google Messages is the default texting app on most newer Android phones. Open the conversation with the person you want to block, then tap the three-dot menu icon in the top right corner. Select Block and report spam or just Block depending on your phone's version. A confirmation window will appear — tap Block again to confirm.

Once blocked, that person's messages will no longer appear in your main inbox. If they send you a text, it goes directly to a hidden folder. You can still see blocked messages if you want to — they're stored in a separate section, usually labeled Blocked or Spam, which you can access through the app's menu.

Block a number using Samsung Messages

If you have a Samsung phone, you may be using Samsung Messages instead of Google Messages. Open the text conversation you want to block, then press and hold the conversation thread until it highlights. Tap the trash or delete icon, then look for a Block sender option that may appear. If you don't see it there, tap the three-dot menu at the top of the conversation and select Block number.

On some Samsung models, you can also block a number by opening the conversation, tapping the contact name at the top, and selecting Block from the contact details screen. The exact location varies slightly between Samsung versions, but the option is always in one of these two places.

Block a number through your phone's system settings

If you want to block a number at the system level rather than just in your messaging app, go to Settings on your Android phone. Tap Apps or Applications, then find and select your messaging app (Google Messages, Samsung Messages, or whichever you use). Tap Notifications and look for a Blocked contacts or Block numbers option.

This method is less direct than blocking from the app itself, and it may only silence notifications rather than hiding the messages completely. For most people, blocking directly from the messaging app is faster and more effective. System-level blocking is useful if you want to block a number from multiple apps at once, but it requires more steps.

Unblock a number if you change your mind

If you blocked someone and want to unblock them, the process is straightforward. In Google Messages, open the menu (three dots), tap Settings, then Blocked numbers. You'll see a list of everyone you've blocked. Find the number you want to unblock and tap the minus sign or Unblock button next to it.

In Samsung Messages, go to the menu, select Settings, then Block list or Blocked numbers. Tap and hold the number you want to unblock, then select Unblock. Once you unblock someone, their messages will start appearing in your inbox again, and they'll be able to reach you normally.

What happens when you block someone

When you block a number on Android, that person can still send you text messages — they just won't know they're blocked. The messages arrive on your carrier's servers but don't show up in your main inbox. You won't get a notification when they text you, and the conversation thread disappears from your normal view.

The blocked person won't receive a notification saying they've been blocked, and they won't see a delivery confirmation or read receipt. From their perspective, the message simply doesn't show as delivered. If they call you, the call will go through normally unless you've also blocked them at the carrier level (which is a separate process handled by your phone company).

Carrier-level blocking for extra control

Your phone carrier (Verizon, AT&T, T-Mobile, etc.) offers its own blocking tools that work differently from Android's built-in feature. Carrier blocking happens before the message even reaches your phone, so you won't see it anywhere. Each carrier has its own app or website where you can manage blocked numbers — check your carrier's website or call their customer service to set this up.

Carrier blocking costs extra on some plans but is included free on others. It's more powerful than app-level blocking because it stops the message at the network level, but it's also less flexible — you can't easily check what was blocked. Most people use Android's built-in blocking first, then add carrier blocking only if they're getting repeated harassment from many different numbers.

Frequently Asked Questions

Can someone tell if I blocked them?

No. When you block someone on Android, they won't receive any notification that they've been blocked. Their messages will appear to send normally, but they won't see a delivery confirmation. They might eventually figure it out if they never get responses to multiple messages, but Android doesn't alert them directly.

Where do blocked messages go?

Blocked messages are stored in a hidden folder within your messaging app, usually labeled Blocked, Spam, or Archived. You can view them anytime by going to your app's menu and selecting the blocked messages folder. They don't appear in your main inbox, but they're not deleted — you can read them if you want to.

Can I block someone without opening their message?

Yes. If you have their contact saved in your phone, open your Contacts app, find their name, tap it, and look for a block option in the menu. You can also block a number directly from your call or message history without opening a conversation. The exact steps vary by phone, but the option is usually in a menu or settings area within the app.

Will blocking stop calls from that number too?

Blocking through your messaging app stops text messages but usually doesn't block calls. If you want to block both calls and texts, you need to block the contact through your phone's system settings or through your carrier's blocking service. Some phones have a separate Block contacts option in Settings that blocks both at once.

What if I block someone and they text me from a different number?

Blocking only affects the specific number you blocked. If someone texts you from a different phone or number, you'll see that message normally. You can block multiple numbers one at a time, but there's no way to block a person across all possible numbers they might use. You'd need to block each new number as it appears.
