The quickest way to block a number on Samsung

Open the Phone app, find the number you want to block in your call history or contacts, and tap and hold on it until a menu appears. Select "Block number" or "Add to reject list" — the exact wording depends on your Samsung model and Android version. The blocked number will no longer reach you by call or text.

If you do not see the number in your call history yet, you can add it manually. Open Contacts, tap the plus icon to create a new contact, enter the number, then go back and block it from the contact card itself.

Samsung phones also let you block numbers directly from an incoming call. When someone calls, tap the decline button, and some models will when ready offer you the option to block that caller.

Key Takeaways

  • The Phone app is the fastest place to block a number — tap and hold the number in your call history, then select "Block number."
  • Blocked numbers cannot reach you by call or text, and you will not see notifications from them.
  • You can block a number before it ever calls you by creating a contact and blocking it from the contact card.
  • Different Samsung models use slightly different menu labels, but the process is the same across all recent devices.
  • Blocked numbers are stored in a list you can view and unblock at any time through your Phone app settings.

Blocking a number from your call history

This is the most common way to block someone. 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 on it for about two seconds until a menu pops up with several options.

Look for "Block number," "Block contact," or "Add to reject list" depending on your phone's Android version and Samsung interface. Tap that option, and the number is blocked when ready. You will not receive calls or text messages from that number going forward.

Blocking a number from your contacts

If the number is already saved in your contacts, open the Contacts app and find the person's name. Tap on their contact card to open their full details. Look for a menu icon (three dots) in the top right corner or a "More" option, then select "Block contact" or "Block number."

This method is useful if you want to block someone you know but do not want to delete their contact information. The contact stays in your phone, but all calls and texts from them are silenced.

Blocking an unknown or new number

If you want to block a number that has never called you, open your Contacts app and create a new contact. Enter the phone number you want to block in the phone field, then save it with a name like "Spam" or "Block This." Once the contact is saved, open it again and use the menu to block it.

Alternatively, some Samsung phones let you go directly to your Phone app settings and add a number to your block list manually. Look for "Settings" or "Call settings" in the Phone app menu, then find "Block numbers" or "Reject list" and add the number there.

Where your blocked numbers are stored

Samsung stores all your blocked numbers in one place so you can review or unblock them later. Open your Phone app and tap the menu icon (three lines or three dots), then look for "Settings" or "Call settings." Find the option labeled "Block numbers," "Blocked contacts," or "Reject list."

This list shows every number you have blocked. If you change your mind about blocking someone, tap their number and select "Unblock." They will be able to call and text you again when ready.

What happens when you block a number

When you block a number on Samsung, that person cannot call you, and their calls go straight to voicemail without your phone ringing. Text messages from blocked numbers do not appear in your message threads — they are either deleted or stored separately depending on your settings.

The blocked person does not receive a notification that they have been blocked. From their perspective, your phone may ring once before going to voicemail, or they may hear a message saying the call cannot be completed. They will not know for certain that you blocked them.

You also will not see missed call notifications or message alerts from blocked numbers. Your phone treats them as if they do not exist, which is why blocking is effective for unwanted calls and texts.

Blocking vs. other call management options

Samsung offers a few different ways to handle unwanted calls beyond straightforward blocking. Some phones have a "Do Not Disturb" mode that silences all calls except from your contacts, and others have a "Call Filter" or spam detection feature that automatically flags suspicious numbers.

Blocking is permanent until you unblock, while Do Not Disturb can be turned on and off. If you want to silence calls from a specific person but keep the option to hear from them later, Do Not Disturb might be better. If you never want to hear from someone again, blocking is the right choice.

You can also report a number as spam or scam through your Phone app on many Samsung models. This sends information to Samsung or your carrier about the number, which helps protect other users.

Frequently Asked Questions

Can a blocked number tell that I blocked them?

No. A blocked person will not receive a notification. They may suspect they are blocked if calls consistently go to voicemail, but Samsung does not send them any message confirming it.

What if I accidentally block someone I want to hear from?

Open your Phone app, go to Settings, find your block list, and tap the person's name or number. Select "Unblock," and they can call and text you again right away.

Do blocked numbers still see my voicemail greeting?

Yes. When a blocked number calls, the call goes to voicemail, and they can leave a message. You will not be notified of the voicemail, but it will be stored in your voicemail inbox if you check it manually.

Can I block a number that is not in my contacts?

Yes. You can block any number by entering it manually in your block list through your Phone app settings, or by creating a contact for it first and then blocking the contact.

Will blocking a number also block their text messages?

Yes. Blocking a number on Samsung blocks both calls and text messages. You will not receive SMS or MMS messages from that number.
