Hiding a number when outgoing calls is a feature that can be useful in situations ranging from personal data protection to professional necessity, such as calling strangers at work or placing ads on boards, hiding the number will help to avoid unwanted callbacks and spam.

On Xiaomi smartphones (including the Redmi line, POCO and Mi) there are several ways to hide the number: through settings MIUI, assisted USSD-But before you start, make sure that your operator does not block this feature. For example, MTS, Beeline and MegaFon in Russia usually allow the concealment of a number, but may charge an additional fee for the service.

Also, some organizations (banks, government agencies) automatically reject calls with hidden numbers, and if you need to call such a service, it is better to temporarily disable the concealment.

Method 1: Hiding the number through MIUI settings

The simplest and most official method is to use the built-in MIUI shell settings. This method works on most modern Xiaomi devices, including Android 12/13/14 models with MIUI 13/14 firmware.

1. Open the phone application (pipe icon).

• 💳 Balance SIM-Cards (some operators are blocking) USSD zero-balance).
• 📱 Fare compatibility (check with the operator whether the number is supported by concealment).

Method 3: Hiding the number through the prefix before the call

If you don't want to change your settings on a permanent basis, you can selectively hide the number for single calls, and you need to prefix the number before the subscriber number. Most operators support the standard code *31#, but there are alternatives:

• 📞 *31# – standard prefix for hiding (works for MTS, MegaFon, Tele2).
• 🔒 #31# – Cancel Hiding for a single call (if the default number is hidden).
• 🌍 + — If you call an international number, dial first. +, 31#, then the country code and the number.

Example: To call 79123456789 with a hidden ID, dial:

*31#79123456789

If the prefix doesn’t work, try adding a pause: dial *31#, then press the call button, wait for the beep and enter the number manually.
