You blocked a number during a wave of spam calls — and now you’re not sure whether you accidentally blocked a legitimate contact. Or you want to reconnect with someone you blocked months ago but can’t remember their number. Whatever the reason, finding blocked numbers on Android isn’t as obvious as it should be.
Android keeps its blocked numbers list in several possible places depending on your device, your Android version (14, 15, or 16), and which app you used to block. The location varies between Samsung, Google Pixel, and other manufacturers — which is why so many people get confused.
This guide shows you exactly where blocked numbers live, how to view the full blocked list, and how to unblock any number on Samsung, Pixel, and other Android phones.
1. Find blocked numbers in the Phone app
The quickest route on most devices is the dialer itself:
- Open the Phone app.
- Tap the three dots (menu) in the top-right corner.
- Go to Settings → Blocked numbers (on some devices: Call settings → Blocked numbers).
You’ll see the complete list of numbers blocked for calls. This works on stock Android and on phones using the Phone by Google app.
2. Check the Messages app
Blocking in the Phone app stops calls; blocking in the Messages app stops texts — and the two lists are stored separately. If you blocked someone from a text thread, check:
- Open Google Messages.
- Tap your profile icon → Messages settings (or Spam & blocked on older versions).
- Open Blocked to see numbers blocked from messaging.
To fully block a contact, you often need to block them in both apps — or use the unified block option when available.
3. Look in Google Contacts
On Pixel phones and devices running the Google Phone app, blocked contacts also surface through Contacts:
- Open Google Contacts.
- Tap Fix & manage (bottom tab) → Blocked numbers.
On Android 14 and later, the system-level block list is shared here: unblocking a number from Contacts removes it everywhere the Google Phone app applies blocking.
4. Find blocked numbers on Samsung (One UI)
Samsung keeps its own blocking layer on top of Android’s, so Galaxy owners have a dedicated path:
- Open the Samsung Phone app.
- Tap the three dots → Settings → Block numbers.
- The blocked list appears with an option to remove entries individually.
Alternatively, go to Settings → Apps → Phone → Block numbers, or check Samsung Messages → three dots → Settings → Block numbers and messages → Blocked numbers.
Note: if you previously blocked a number in the Google Phone app and later switched to Samsung’s dialer (or vice versa), check both lists — they don’t always sync.
5. How to unblock a number on Android
Unblocking takes seconds once you’ve found the list:
- Phone app (Google / stock): Settings → Blocked numbers → tap the X next to the number → Unblock.
- Samsung One UI: Phone app → three dots → Settings → Block numbers → tap the minus (–) icon → confirm.
- Messages: Spam & blocked → select the number → Unblock.
- Contacts: Fix & manage → Blocked numbers → tap the number → Unblock.
After unblocking, calls and texts from that number come through normally again. The person is never notified either way.
6. Use spam protection so you block less often
If you find yourself blocking numbers constantly, Android’s built-in spam defenses can cut the volume before it reaches you:
- Spam protection (Phone by Google): Phone app → Settings → Caller ID & spam → turn on See caller and spam ID and Filter spam calls. Verified businesses show their name; suspected spam is filtered silently.
- Block unknown callers: Phone app → Settings → Blocked numbers → enable Block unknown/private callers. Use with care — legitimate calls from hidden numbers (doctors’ offices, delivery drivers) get silenced too.
- Report spam: in the Recents tab, long-press a spam number → Block / report spam → Report as spam. This helps Google’s database protect everyone else.
On Samsung, the equivalent is Smart Call (Caller ID and spam protection) under Phone settings.
Troubleshooting: common blocked-number problems
Blocked numbers are still calling me.
Most often the number was blocked in only one app (calls vs. messages), or you’re checking a different dialer than the one you used to block. Verify both the Phone and Messages lists. Also check whether a third-party call-blocker app has its own list.
My blocked list is empty but I remember blocking someone.
Carrier-level blocks (made through your operator’s app or codes) don’t appear in Android’s list — contact your carrier. If you blocked through a third-party app you’ve since uninstalled, that list went with it.
Settings look different on my phone.
Manufacturers rename menus freely (Xiaomi’s MIUI, OPPO’s ColorOS, One UI). Use the search bar at the top of the Settings app and type “block” — it jumps straight to the right screen.
Frequently asked questions
How do I find blocked numbers on Android?
Open the Phone app → three dots → Settings → Blocked numbers. On Samsung, use the Phone app → three dots → Settings → Block numbers. Messages blocks live under Google Messages → profile → Spam & blocked.
Where are blocked numbers stored on Android?
In a system-level block list managed by Android, accessible through the Phone app, Messages app, and Google Contacts. Samsung adds its own layer in One UI, and carriers can maintain a separate network-level list.
How do I unblock a number on Android?
Find the blocked list using the steps above, tap the X or minus icon next to the number, and confirm. Calls and texts resume immediately.
Can I see blocked messages on Android?
Yes — in Google Messages, open Spam & blocked to view messages from blocked senders that were filtered out. You can unblock or delete them from there.
Can blocked numbers leave voicemails?
Blocked calls typically go straight to voicemail if you have it set up, so a blocked caller may still leave one. The phone won’t ring or notify you.
Do blocked contacts know they’ve been blocked?
No. Their calls and messages appear to go through normally on their end; you just never see them.
