The fastest way to block a number on Samsung

Open the Phone app, find the number you want to block in your call history or contacts, press and hold it, then tap Block number. The blocked number can still leave voicemails, but their calls won't ring through and won't show up in your call log. If you want to block a number that isn't in your history yet, go to Contacts, create a new contact with that number, save it, then use the same long-press method to block it.

Samsung phones running Android 11 and newer have this blocking feature built into the Phone app itself. Older Samsung phones may have a slightly different path — you might need to go to Settings > Apps > Phone > Permissions, or the block option might live in a separate Contacts app — but the principle is the same: find the number, press and hold, select block.

Blocked numbers are stored in a list you can view and unblock anytime. To see your blocked list, open the Phone app, tap the three-dot menu (or More), then look for Settings or Blocked numbers. The exact wording depends on your Android version and Samsung's interface version, but it's always in the Phone app settings.

Key Takeaways

  • You can block a number directly from your call history by pressing and holding it and selecting Block number from the menu.
  • Blocked callers can still leave voicemails, but their calls won't ring through to you and won't appear in your call log.
  • You can view and manage your full list of blocked numbers in the Phone app's settings under Blocked numbers.
  • If you need to block a number not in your history, create a contact for it first, then use the same long-press blocking method.

Blocking from your call history

The most common way to block someone is right after they call. Open your Phone app and look at the recent calls list. Find the number or contact name you want to block, then press and hold it until a menu appears. Tap Block number (or sometimes Block contact if it's a saved contact). That's it — the number is now blocked.

Once blocked, that number's future calls go straight to voicemail without ringing your phone. The calls won't show up in your call history, so you won't see a record that they tried to reach you. If you change your mind later, you can unblock the number from the same Blocked numbers list in your Phone app settings.

Blocking a number from your contacts

If you have a contact saved and want to block them, open your Contacts app, find the person, and tap their name to open their full contact card. Look for a menu button (usually three dots in the top right corner) and tap it. You should see a Block contact or Block number option. Tap it to block all numbers associated with that contact.

This method is useful when you want to block someone you know but no longer want to hear from. Blocking the contact itself means that if they call from a different number, you'll still receive it — only the numbers you've explicitly blocked are filtered. If you want to block someone completely regardless of which number they use, you may need to block each number separately as they call.

Blocking an unknown or new number

If you want to block a number that hasn't called you yet, or one that isn't in your call history, you'll need to create a contact for it first. Open your Contacts app, tap the plus sign or Create contact, enter the phone number you want to block, and save it (you can use a generic name like "Block" or "Spam"). Then open that contact, tap the menu, and select Block contact.

Alternatively, some Samsung phones let you type a number directly into the Blocked numbers list without creating a contact. Go to Phone app settings, find Blocked numbers, and look for an option to add a new number manually. The exact steps vary by Android version, so if you don't see this option, the contact method above will work on any Samsung phone.

What happens when you block a number

When you block a number on Samsung, the blocked caller's experience is straightforward: their call goes to your voicemail, and they hear a message (usually your voicemail greeting or a generic message) instead of a ringing phone. They won't know for certain that they're blocked — it sounds like you're unavailable — but they also won't receive a notification saying the call was blocked.

On your end, blocked calls don't ring, don't vibrate, and don't appear in your call log. If the blocked number texts you, the message still arrives in your Messages app (blocking only affects calls, not texts). Some Samsung phones have a separate option to block texts from the same number, which you can usually find in your Messages app by long-pressing a conversation and selecting Block.

Viewing and managing your blocked list

To see all the numbers you've blocked, open your Phone app and tap the menu button (three dots or lines, depending on your phone). Look for Settings, then Blocked numbers or Block list. You'll see a list of every number you've blocked. From here, you can tap any number to unblock it if you change your mind.

If you have a lot of blocked numbers and want to unblock several at once, some Samsung phones let you select multiple numbers and delete them together. Look for a checkbox or selection option in your blocked list. If your phone doesn't have this feature, you'll need to unblock them one at a time by tapping each number and confirming the unblock.

Blocking texts from the same number

Blocking a call doesn't automatically block text messages from that number — they'll still arrive in your Messages app. If you want to block both calls and texts, you need to block the number in your Messages app separately. Open Messages, find the conversation with the number you want to block, press and hold it, and tap Block or Block number.

Some Samsung phones show a combined block option that covers both calls and texts, while others require you to block in each app separately. If you block in the Phone app but still receive texts, open Messages and block the number there too. Once blocked in both places, you won't receive calls or texts from that number.

Frequently Asked Questions

Can a blocked number tell they've been blocked?

No. When a blocked number calls, they hear your voicemail greeting or a generic message, which sounds the same as if you were unavailable. They won't receive a notification saying they're blocked. However, if they call repeatedly and always reach voicemail, they may suspect they're blocked, but Samsung doesn't send them an explicit confirmation.

Will blocked numbers still see my text messages?

Blocking a number in your Phone app doesn't block texts. If you send a text to a blocked number, it will still be delivered. To prevent texts from reaching you from that number, you need to block it separately in your Messages app. Blocking in one app doesn't automatically block in the other.

Can I block calls but still receive texts from someone?

Yes. Block the number in your Phone app to stop calls, but don't block it in Messages. You'll stop receiving calls from them but will still see their text messages. This is useful if you want to ignore someone's calls but stay able to read their texts.

What if I accidentally blocked someone?

Open your Phone app, go to Settings, find Blocked numbers, and look for the contact you blocked by mistake. Tap it and select Unblock. Once unblocked, their calls will ring through again and appear in your call log. You can block and unblock numbers as many times as you need.

Do blocked numbers go to voicemail or just disappear?

Blocked calls go to your voicemail. The blocked caller hears your voicemail greeting and can leave a message, but you won't be notified that they called. The call won't appear in your call history, but if they leave a voicemail, you can listen to it later in your voicemail app if you choose to.
