The simplest way to block texts on Android

Open the Messages app (or whatever texting app came with your phone), find the conversation from the person you want to block, and press and hold their name until a menu appears. Tap Block or Block number. That's it — their texts will no longer reach your phone, and they won't be told they're blocked.

If you don't see a Block option in your Messages app, open your phone's Settings, search for "blocked numbers" or "block contacts", and add the number manually from there. The exact wording changes between phone makers (Samsung, Google Pixel, OnePlus, etc.), but the feature exists on every Android phone made in the last five years.

Blocked texts don't disappear from your phone — they move to a separate folder you can view later if you need proof of the messages. You can unblock someone at any time by going back to Settings and removing them from the blocked list.

Key Takeaways

  • Most Android phones let you block a number directly from the Messages app by pressing and holding the conversation, then tapping Block.
  • Blocked messages go to a hidden folder rather than disappearing, so you can review them later if needed.
  • The person you block will not receive a notification that they are blocked.
  • You can unblock someone at any time through your phone's Settings under blocked numbers or contacts.
  • If your Messages app doesn't have a Block button, your phone's Settings menu will have a separate blocked numbers section.

Blocking through your phone's Settings instead

If your Messages app doesn't show a Block option, or if you want to block a number before you've received a text from them, use your phone's Settings. Open Settings, then search for "blocked" — most Android phones will show you "Blocked numbers" or "Block contacts" in the results.

Tap that option and select Add a number or the plus icon. Type in the phone number or contact name you want to block. Some phones also let you block by contact — if the person is already in your contacts, you can select their name instead of typing the number.

Once you add them to the blocked list, any text from that number will be filtered out. Some phones also block calls from that number at the same time, though this varies by manufacturer.

What happens to blocked messages

When you block someone, their texts don't vanish — they go into a hidden folder called Blocked messages or Spam, depending on your phone. You can still read them if you need to, but they won't show up in your main inbox or trigger notifications.

This matters if you're blocking someone you might need evidence from later (a harassing contact, for example). The messages stay on your phone in case you need to show them to someone else or refer back to them. You can delete them manually if you want them gone entirely.

If you unblock the person, old blocked messages don't reappear in your main inbox — they stay in the blocked folder. New messages from them will go to your regular inbox once they're unblocked.

Blocking spam and unknown numbers

Many Android phones have a separate spam filter that works alongside manual blocking. Open your Messages app and look for a Spam or Spam and blocked tab. Any messages flagged as spam land there automatically, and you can mark additional messages as spam by pressing and holding them and selecting Report spam or Mark as spam.

If you want to block all calls and texts from unknown numbers (people not in your contacts), go to Settings and search for "unknown" or "caller ID". Some phones have a toggle for Block unknown callers or Filter unknown senders. Turn this on and you'll only receive messages from people you've saved in your contacts.

Be careful with this setting if you're expecting texts from businesses or services that use random numbers — delivery confirmations, appointment reminders, and password reset codes often come from numbers not in your contacts.

Blocking contacts vs. blocking numbers

If the person is saved in your contacts, you have two options: block them as a contact, or block their specific number. Blocking the contact is simpler — open your Contacts app, find their name, tap the menu (three dots), and select Block contact or Block number.

Blocking a number is better if you want to block just one of their phone numbers but stay in touch through another number or method. If someone has multiple numbers and you only want to block one, go to Settings and add that specific number to your blocked list instead of blocking the entire contact.

If you block a contact, you'll still see their name in your contacts list — they're just blocked from reaching you. You can unblock them the same way: open their contact, tap the menu, and select Unblock.

Why a blocked person can still reach you through other apps

Blocking a number in your Messages app or Settings only blocks SMS and MMS texts — the traditional text message system. If the person has your contact information, they can still reach you through Facebook Messenger, WhatsApp, Instagram, email, or any other app.

If you need to block someone completely, you'll need to block them separately in each app they might use. Open the app, find their profile or conversation, and look for a Block or Report option. Most messaging apps have this feature in their settings or in the menu for that person's conversation.

This is why blocking is most effective when combined with not sharing your contact details with people you don't trust. Once someone has your number or username, they can find ways around a single block.

Unblocking someone and what to expect

To unblock someone, go to Settings, find Blocked numbers or Blocked contacts, and look for the person's name or number in the list. Tap it and select Unblock. They'll when ready be able to text you again, and their messages will go to your regular inbox instead of the blocked folder.

Unblocking does not send them a notification — they won't know you've unblocked them unless you tell them. If they've been trying to reach you while blocked, their old messages won't suddenly appear in your inbox. Only new messages sent after you unblock them will come through.

If you blocked someone by accident, unblocking them is just as quick. There's no waiting period or confirmation — as soon as you remove them from the blocked list, the block is gone.

Frequently Asked Questions

Can someone tell if I've blocked them?

No. When you block someone on Android, they won't receive a notification. If they try to text you, the message will appear to send normally on their end, but it won't reach your phone. They might eventually realize you're not responding, but Android doesn't tell them they're blocked.

Do blocked messages take up storage space on my phone?

Yes, blocked messages stay on your phone in a hidden folder and count toward your storage. If you want to free up space, you can delete them manually from the blocked messages folder. Deleting them is permanent — you won't be able to see them again.

What if someone texts me from a different number after I block them?

If you block a specific number, they can text you from a different number and you'll receive it. If you block them as a contact, blocking applies to all their numbers in your contacts. To block multiple numbers from the same person, add each number to your blocked list separately.

Will blocking someone also block their calls?

Usually yes, but it depends on your phone. Most Android phones block both texts and calls from a blocked number. Some older phones or custom versions may only block texts. Check your phone's Settings under blocked numbers to see what's blocked.

Can I block a number without saving it to my contacts first?

Yes. Go to Settings, find Blocked numbers, and add the number directly without saving it as a contact. You can also block a number from a text message by pressing and holding the conversation and selecting Block, even if you've never saved their contact information.
