USSD codes allow you to quickly check your mobile number and access various phone functions across different carriers and devices[1]. These codes are short strings typed directly into your phone’s dialer, followed by the call button, to retrieve the information instantly without needing internet access[5].
To check your mobile number using USSD codes, use the following codes based on your carrier (India):
- Airtel: *282#
- Vodafone Idea: *111*2# or 1311#
- Reliance Jio: *1#
- BSNL: *222#
Simply open your phone’s dialer, enter the relevant code above, and press the call button. Your mobile number will appear on the screen[1].
For Sunrise (Switzerland): Dial *122# and press the call button to display your own mobile number. Note that this may not work on Apple devices[7].
General Codes Useful On Most Phones:
- Display IMEI number: *#06# (works on almost all devices)[3][4][6]
- iPhone Field Test Mode: *3001#12345#* (advanced info including SIM and network details)[2][5]
If a code does not work for your carrier or country, consult your carrier’s website or contact their customer support for the correct code[1].
