Where Xiaomi Phones Store Locked Numbers: 5 Ways to Find a Blacklist

Are you accidentally blocking an important number or suspecting that one of your contacts has been blacklisted on Xiaomi?Unlike other manufacturers, MIUI-based smartphones don’t hide this feature in the most obvious places. Moreover, the location of the lock menu may vary depending on the firmware version and device model — whether it’s the Redmi Note 12, POCO X5 or the flagship Xiaomi 14.

In this article, we will not only show you all the possible ways to access blocked numbers, but also explain how to restore deleted contacts from the blacklist, why some numbers are blocked automatically (for example, spam calls), and what to do if the standard MIUI settings do not display the desired information. You will also learn about hidden features that allow you to export a list of blocked numbers or sync it with your Mi Account.

1. Standard path: the "Block" menu in the phone settings

The most obvious way to find locked numbers is through the basic MIUI settings, which works on most devices, from MIUI 10 to the current MIUI 15 (2026).

1. Open the Settings app (cog icon).
2. Go to the Appendix section → Application management.
3. At the top of the screen, select the Block tab (on some firmware it may be called Spam and Lock).
4. Slip on the item "Blocked numbers" or "Black list".

Here you will see the full list of blocked contacts, as well as the history of incoming calls and SMS from these numbers. Please note: if the list is empty, but you are sure that you have blocked numbers before, check sync with Mi Account (more about this in the next section).

⚠️ Note: Some models (e.g. Redmi) 9A with lightweight firmware), the "Blocking" section may not be available, in which case use alternative methods from the following sections.

2. Alternative method: through the application "Phone"

If the standard path didn’t work, try looking for a blacklist directly in the Phone app, which is especially relevant for devices with MIUI 12 and later, where lock functionality is integrated into calls:

• 📱 Open the phone application (pipe icon).
• 🔍 Press three points (⋮) in the upper right corner and select Settings.
• 📵 Go to the section Blocking numbers or Spam and blocking.
• 📋 Here you will see a list of all blocked contacts, as well as options for adding new ones.

In this menu, you can not only view blocked numbers, but also set up automatic spam blocking through Xiaomi and Google services, for example, you can enable filtering through a database of fraudulent calls, which is updated in real time.

💡

If an unknown number appears on the lock list but you don’t remember how it got there, check the call history – it may have been an automatically blocked spam call.

3.Sync with Mi Account: How to Restore List After Resetting

One of the useful features of MIUI is synchronizing locked numbers with a cloud-based Mi Account, which means that even after you reset your phone to factory settings or change your device, you can restore the blacklist. Here's how it works:

1. Make sure you are logged in to Mi Account (check in Settings → Accounts).
2. Go to Settings → Applications → Application Management → Lock.
3. Enable the option to Sync blocked numbers (if it is disabled).
4. If the list is empty, click Restore or Import from the cloud.

Important: synchronization only works when you are actively connected to the Internet. If you have changed your device, log in to the same Mi Account as your previous smartphone. It can take up to 5 minutes to sync locked numbers - don't interrupt the process, even if the list didn't appear immediately.

4. Hidden Settings: How to Find a Lock Through an Engineering Menu

If standard methods don’t work, you can try accessing locked numbers via an engineering menu (or ##4636##) that is suitable for power users and requires caution, as incorrect actions can disrupt the phone.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Phone Information.
3. Scroll down and find the Call Blocking or Call Blocking section.
4. System locks can be displayed here, including operator-level numbers.

⚠️ Warning: Changing the settings in the engineering menu without understanding their purpose can lead to network failures or complete loss of communication.

5.Recovering deleted numbers from blacklist

If you accidentally delete a number from a locked number or the list is reset after the MIUI update, you can try to restore it.

• 🔄 Restore from backup: If you created a backup through Settings → Additionally. → Backup, restore the data from the last copy, note that this will return all the settings of the phone to the state at the time of creation of the backup.
• ☁️ Cloud backup Mi Account: Check if blacklist sync is enabled (see Section 3).If yes, try logging out and logging in again - sometimes this works as a sync "reset.
• 📱 Local Logs: Apps like Call Logs Backup & Restore (available on Google Play) can save your blocking history.

If none of the methods worked, but the number is critical (for example, it was a blocked scammer who started bothering you again), try manually adding it back to the blacklist.

1. Open Contacts and find the right number.
2. Slip on him, pick another one (⋮) → Lock down.
3. Confirm the action in the window that appears.

6 Automatic lock: why numbers are added to the blacklist themselves

Many Xiaomi users face a situation where numbers are blocked without their participation, due to built-in spam protection mechanisms.

• 🤖 Spam blocking service MIUI: By default, the option to block suspicious calls in the phone settings is enabled.It uses the Xiaomi and Google database to identify fraudulent numbers.
• 📊 Operator Algorithms: Some mobile operators (e.g. MegaFon or Beeline) automatically block known spam numbers at the network level. MIUI.
• 🔄 Security Updates: After Updating MIUI The system can reset some lock settings or add numbers from new spam databases to the blacklist.

1. Go to Settings → Applications → Application Management → Lock.
2. Turn off the options to block suspicious calls and filter messages.
3. In the Phone app (Recent tab) click ⋮ → Settings → Block and spam and disable all automotive filters.

Automatic spam blocking is useful, but sometimes wrong. Check the blacklist regularly for false positives, especially if you are waiting for an important call from an unknown number.
