Where to look for numbers you've blocked

The place to find a blocked number depends on your phone type and which app you used to block it. On most phones, blocked numbers live in your phone's native call-blocking settings, not in your contacts or call history. If you blocked someone through your carrier — Verizon, AT&T, T-Mobile, or another provider — you'll need to check their app or website instead.

The fastest way is to open your phone's settings, find the call-blocking or "Do Not Disturb" section, and look for a list called "Blocked Numbers" or "Blocked Contacts". On some phones this list is buried under Privacy or Phone settings. If you can't find it there, check whether you blocked the number through a third-party app like Nomorobo, RoboKiller, or your carrier's own blocking tool — each stores blocked numbers in its own place.

Key Takeaways

  • Blocked numbers on iPhones appear in Settings > Phone > Blocked Contacts, while Android phones typically show them in Phone > Settings > Blocked Numbers or Call Settings > Blocked Calls.
  • If you blocked a number through your carrier's app or website, you must check that app or your carrier account online, not your phone's settings.
  • Third-party blocking apps like Nomorobo or RoboKiller keep their own separate list of blocked numbers inside their app.
  • Once you find a blocked number, you can unblock it from the same menu where you view it, usually by tapping the number and selecting "Unblock".

Finding blocked numbers on iPhone

On iPhone, go to Settings, then tap Phone. Scroll down and tap Blocked Contacts. This shows every number you've blocked directly through your phone's settings. The list includes phone numbers, email addresses, and FaceTime contacts you've blocked.

If you don't see a number you thought you blocked, it may have been blocked through a different method. Check your Messages app — you can block numbers there too, and they won't appear in the Phone settings list. Open Messages, find the conversation, tap the contact at the top, scroll down, and look for "Block this Caller" or similar language. If you blocked it there, it will show in a separate Messages blocked list, not in Phone settings.

You can also block numbers through iCloud or through your carrier's app. If you use AT&T Call Protect, Verizon Call Filter, or T-Mobile Scam Shield, those apps maintain their own blocked lists separate from your phone's native settings.

Finding blocked numbers on Android

On Android, the path varies by manufacturer and Android version. Most phones use Phone app > Settings > Blocked Numbers or Phone app > Settings > Call Settings > Blocked Calls. Open your Phone app, tap the three-dot menu or Settings icon, and look for "Blocked" or "Block list".

Samsung phones often put this under Phone > More options > Settings > Reject calls > Rejection list. Google Pixel phones use Phone > Settings > Blocked numbers. If you can't find it in the Phone app, check your Messages app — Android lets you block numbers there as well, and they show in a separate blocked list within Messages.

Like iPhone, Android also supports carrier-level blocking. If you've blocked a number through your carrier's app, you won't see it in your phone's native settings. Check your carrier's app directly or log into your carrier account online.

Checking your carrier's blocked list

Verizon Call Filter, AT&T Call Protect, and T-Mobile Scam Shield each maintain their own blocked-number lists. These are separate from your phone's built-in blocking feature. To view them, open the carrier's app on your phone or log into your carrier account on a computer.

For Verizon, open the Call Filter app and look for "Blocked" or "Manage Blocks". For AT&T, open Call Protect and find the blocked-calls section. For T-Mobile, open Scam Shield and check the blocked-numbers list. Each app shows numbers you've blocked through that specific service, not through your phone's native settings.

If you don't have the carrier app installed, you can also log into your carrier account online. Go to your carrier's website, sign in, and navigate to call-blocking or call-management settings. You'll see the same blocked list there.

Checking third-party blocking apps

If you use Nomorobo, RoboKiller, Truecaller, or another third-party blocking app, open that app and look for a "Blocked" or "Block list" section. Each app stores its blocked numbers inside the app itself, not in your phone's settings.

Some of these apps show blocked calls in a separate tab or menu. RoboKiller, for example, displays blocked robocalls in a "Blocked" section. Truecaller shows them under "Blocked contacts". The exact location depends on the app, but it's usually accessible from the main menu or a settings icon.

Unblocking a number once you find it

Once you locate the blocked number, unblocking it is straightforward. In your phone's native settings, find the number in your blocked list, tap it, and select "Unblock" or a similar option. On iPhone, tap "Edit" in the Blocked Contacts list, then tap the minus sign next to the number and confirm.

In carrier apps and third-party apps, the process is similar: find the number, tap it, and select "Unblock". The number will then be able to call or message you again. If you unblock a number by mistake, you can block it again using the same method you used the first time.

Why you might not find a number you blocked

If you can't find a blocked number, it may have been blocked through a different method than you remember. Check all three places: your phone's native settings, your carrier's app, and any third-party blocking apps you use. A number blocked in one place won't show up in another.

Another possibility is that you blocked the number through a messaging app like WhatsApp, Telegram, or Signal. These apps have their own internal blocking features, and blocked numbers don't appear in your phone's call-blocking settings. Open the app, find the contact, and look for a "Block" or "Blocked contacts" option.

If you still can't locate it, the number may have been blocked by a family member using parental controls or a shared account. Check whether your phone is linked to a family account or whether parental controls are active.

Frequently Asked Questions

Can I see who blocked me?

No. When you call someone who has blocked you, you typically hear a busy signal, a message that the number is unavailable, or the call goes straight to voicemail. There's no way to know for certain that you've been blocked without asking the person directly. Some carriers offer caller ID services that may indicate a block, but these are not reliable.

Will a blocked number know I unblocked them?

No. Unblocking a number is invisible to the other person. They won't receive a notification that you've unblocked them. They'll only know if they try to call or message you and you respond.

What happens when a blocked number tries to call me?

On most phones, the call goes to voicemail or the caller hears a busy signal. Some phones show a notification that a blocked number tried to reach you. The blocked caller typically doesn't know they've been blocked — they just experience a failed call.

Can I block a number I don't have saved as a contact?

Yes. You can block any number, whether it's in your contacts or not. Find the number in your call history or messages, tap it, and select "Block this number" or similar language. You don't need to save it as a contact first.

If I block a number on my phone, will it also be blocked on my other devices?

It depends. If you block a number through your phone's native settings, it typically blocks only that device. If you block through your carrier's app or through iCloud (on iPhone), it may sync across your devices. Check your carrier's documentation or your phone's settings to confirm how blocking works across your devices.
