Where your phone stores blocked numbers

Your blocked numbers live in your phone's settings, not in your contacts or call history. On iPhone, go to Settings > Phone > Blocked Contacts. On Android, open the Phone app, tap the three dots in the top right, select Settings, then Blocked Numbers or Call Blocking (the exact name varies by phone maker and Android version). Some Android phones also let you manage blocks through Messages instead of Phone.

If you use a carrier like Verizon, AT&T, or T-Mobile, they may also have a separate blocking service with its own list. Carrier blocks work at the network level, so they stop calls before they reach your phone. You can check these through your carrier's app or website, but they are managed separately from your phone's built-in list.

Third-party apps like TrueCaller, RoboKiller, or your phone's default call-screening app keep their own block lists too. These are harder to find because they live inside the app itself, not in your phone's main settings.

Key Takeaways

  • iPhone blocked numbers are in Settings > Phone > Blocked Contacts, while Android phones store them in the Phone app settings under Blocked Numbers or Call Blocking.
  • Your carrier (Verizon, AT&T, T-Mobile) may maintain a separate block list that you can check through their app or website.
  • Third-party call-blocking apps keep their own lists inside the app, separate from your phone's system blocks.
  • Unblocking a number is as straightforward as finding it in the list and selecting Remove or Unblock, though the exact wording depends on your phone.

How to unblock a number on iPhone

Open Settings, go to Phone, then tap Blocked Contacts. You will see a list of every number you have blocked. Find the one you want to unblock, swipe left on it (or tap Edit, then the red minus sign), and select Unblock. The number is now unblocked and can call or text you again.

If you cannot remember which number belongs to which person, look at your recent calls or messages first. Blocked numbers still appear in your call history and message threads — they just do not ring through or notify you. Once you find the number in your call log or messages, you can identify it before unblocking.

How to unblock a number on Android

Open the Phone app and tap the three dots (menu) in the top right corner. Select Settings, then Blocked Numbers or Call Blocking depending on your phone. You will see your blocked list. Tap the number you want to unblock and select Remove, Unblock, or Delete (wording varies by manufacturer). The number is now unblocked.

Some Android phones, especially Samsung, also let you manage blocks through the Messages app. If you blocked a number while texting, you may need to unblock it there instead. Check both the Phone app and Messages app if you cannot find the number in one place.

Finding blocks through your carrier

If you blocked a number through your carrier's service rather than your phone, you need to log into your carrier's account. Verizon customers can use the My Verizon app or website and look for Call Filter or Call Block settings. AT&T users should check the AT&T Mobile Security app. T-Mobile has Scam Shield in the T-Mobile app.

Carrier blocks are useful because they stop spam before it reaches your phone, but they are harder to manage on the go. If you unblock a number at the carrier level, it may take a few minutes to take effect. Your phone's built-in blocks work when ready.

Checking blocks in third-party apps

Apps like TrueCaller, RoboKiller, and Google's Call Screen have their own block lists. Open the app, look for a Settings or Blocked Numbers section (usually in a menu or gear icon), and you will see numbers the app has blocked for you. Some apps block numbers automatically based on spam databases, while others block only numbers you manually added.

To unblock a number in a third-party app, find it in the app's blocked list and tap Remove or Unblock. This only removes it from that app's list — it does not affect your phone's system blocks or your carrier's blocks. If you want the number fully unblocked, you may need to remove it from multiple places.

What happens when you unblock a number

Once you unblock a number, the person can call or text you again, and you will see their calls and messages normally. You will get notifications, and their calls will ring through instead of going to voicemail silently. If they try to reach you while the number is still blocked, they will not know they are blocked — the call just goes to voicemail as if you did not answer.

Unblocking does not send any notification to the person you unblocked. They will not know you removed them from your block list. If you want them to know you are open to contact again, you will need to reach out separately.

Frequently Asked Questions

Can I see who tried to call me while I had them blocked?

No. Blocked calls do not appear in your call history on most phones. However, some carriers log blocked calls in their own records. Check your carrier's app to see if they show a history of blocked calls. Your phone itself will not have a record.

What if I forgot which number I blocked?

Look through your recent calls and messages — blocked numbers still show up there, they just do not ring through. You can also ask the person directly if they have been unable to reach you. Once you find the number in your call log or messages, you can unblock it from there.

Do I have to unblock from my phone and my carrier separately?

Yes. Your phone's block list and your carrier's block list are separate. If you blocked a number on your phone, unblocking it on your carrier's app will not help. You need to unblock it in both places if you blocked it in both places.

Will unblocking a number stop spam calls from that number?

Unblocking only removes the block you set. If the number is a spam number, it may still be flagged by your carrier or a third-party app, which could send it to spam or block it automatically. Unblocking does not change how your phone or carrier identifies spam.
