What are USSD Codes?

USSD codes stand for Unstructured Supplementary Service Data. Simply put, they are used for interactive communication sessions between the user’s mobile phone and the network operator’s system. Unlike SMS, which is a store-and-forward service, USSD allows users to access services directly. When a user dials a USSD code, they receive a response in real-time without the delay associated with SMS messaging. This makes it especially useful for time-sensitive services.

How Do USSD Codes Work?

When you initiate a USSD session, a connection is established between your mobile device and the service provider’s system.

• The user dials a code (e.g., *123#), typically followed by a menu-driven interaction.
• USSD messages are transmitted over the signaling channels, which means they don’t require an internet connection.
• The session remains open until a service is delivered or a transaction is completed, allowing for faster interactions.

For instance, if you’re trying to check your mobile balance or transfer money via mobile banking, USSD provides an efficient method that’s accessible and quick.
