A USSD code is a short code that you dial on your phone to access various services and information from your mobile operator or other providers. USSD stands for Unstructured Supplementary Service Data, and it is a communication protocol that creates a real-time connection between your phone and a server.

To use a USSD code, you just need to dial it on your phone’s keypad and press the call button. Some codes will run automatically, while others will show you a text-based menu that you can navigate with your keypad USSD codes usually start with an asterisk (*) or a hashtag (#) and end with a hashtag (#). For example, *#06# is a common USSD code that displays your phone’s IMEI number.
