What "block numbers" means and why you'd want to show them
When you block a number on your phone, the person calling from that number can no longer reach you — their calls go straight to voicemail and they won't see a "delivered" message. But your phone doesn't automatically tell you which numbers you've blocked. To see your block list, you need to open your phone's settings and navigate to the blocking section. The exact steps depend on whether you use an iPhone or Android device.
You might want to review your blocked numbers to unblock someone, to confirm you blocked the right number, or straightforward to see how many people you've blocked over time. Some people block numbers temporarily during a dispute and forget they did it, then wonder why someone isn't reaching them.
Key Takeaways
- On iPhone, open Settings, tap Phone, then Blocked Contacts to see all numbers you've blocked.
- On Android, the location of your block list varies by manufacturer — Samsung uses Phone app settings, while Google Pixel uses the Phone app's block list menu.
- You can unblock a number from the same screen where you view it, and the person will be able to call you again when ready.
- Some phone carriers also maintain their own block lists separate from your phone's settings, so you may need to check both places.
How to view blocked numbers on iPhone
Open the Settings app on your home screen. Scroll down and tap Phone — it's the green icon with a white phone symbol. Tap Blocked Contacts near the bottom of the menu.
You'll see a list of every number and contact you've blocked. The list shows the phone number or contact name, depending on whether the number is saved in your contacts. If you want to unblock someone, swipe left on their name and tap Unblock, or tap Edit in the top-left corner, select the names you want to unblock, and tap Unblock.
How to view blocked numbers on Android (Samsung)
Open the Phone app — the green icon with a white phone symbol. Tap the three-dot menu icon in the top-right corner and select Settings. Tap Block numbers or Blocked numbers (the exact wording varies by Android version). You'll see your complete block list.
To unblock a number, tap it and select Unblock, or long-press the number and choose Unblock from the menu that appears. The person can call you again as soon as you unblock them.
How to view blocked numbers on Android (Google Pixel)
Open the Phone app and tap the three-dot menu in the top-right corner. Select Settings, then Blocked numbers. You'll see all the numbers you've blocked on this device.
Tap any number to see options to unblock it. Unlike some Android phones, Pixel devices also show you a count of blocked calls and messages at the top of the screen, so you can see how many times blocked numbers have tried to reach you.
Checking your carrier's block list
Your phone's built-in block list is separate from any blocking your carrier (like Verizon, AT&T, or T-Mobile) may have set up. If you've used your carrier's call-blocking service, you'll need to check that separately — usually through their website or a dedicated app.
To find your carrier's block list, log into your account on their website or open their official app. Look for a section called Call Blocking, Call Filter, or Call Protection. The steps vary widely by carrier, so if you can't find it, call your carrier's customer service line and ask them to walk you through viewing your blocked numbers.
What happens when you unblock a number
When you unblock a number, that person can call you, text you, and reach you through FaceTime or other apps when ready. They won't receive a notification that you unblocked them — they'll only know if their call goes through when it previously didn't.
If you blocked someone by mistake, unblocking them restores normal communication. If you blocked someone intentionally but want to give them another chance, unblocking is the only way to let them contact you again. There's no "soft block" option on most phones — blocking is all-or-nothing.
Frequently Asked Questions
Can I see who tried to call me while their number was blocked?
On Google Pixel, yes — the Phone app shows a count of blocked calls. On iPhone and most Android phones, you won't see a record of blocked calls in your recent calls list. If you want to know whether someone tried to reach you, you'd need to unblock them first and ask.
If I block someone and then unblock them, will they know?
No. They won't receive any notification that you blocked or unblocked them. They'll only know something changed if they try to call you and it suddenly works after previously failing.
What's the difference between blocking a number and blocking a contact?
On most phones, there's no practical difference — both prevent calls and texts from reaching you. If you block a contact (a saved name in your phone), the entire contact is blocked. If you block a number, only that specific number is blocked, even if it's not saved in your contacts.
Can I block a number from my carrier instead of my phone?
Yes. Carrier-level blocking is sometimes more effective because it blocks the call before it reaches your phone. However, you can only manage carrier blocks through your carrier's website or app, not through your phone's settings. Many people use both — their phone's block list and their carrier's block list.
Will unblocking a number let them see old messages I didn't send?
No. Unblocking only restores future communication. Any messages they sent while blocked will still be blocked, and they won't receive messages you sent while they were blocked. The past doesn't change.
