Section 1: What Are USSD Codes?

USSD codes, or Unstructured Supplementary Service Data codes, are a communication protocol used by GSM cellular network phones to connect with their provider’s computers. Unlike SMS, which stores and forwards the messages, USSD creates a real-time connection during a session. Here’s what you need to know:

• Structure: Typically, codes are composed of a sequence of characters starting with a * and ending with a #, such as *123#.
• Purpose: Handy for accessing diversified services like balance checks, mobile recharges, and customer support.
• Availability: Universally applicable and accessible via any GSM network-supported mobile phone.

Section 2: How USSD Codes Work

USSD operates as a real-time or session-based connection that allows for interactive, responsive interactions. Here’s a closer look at the process:

• Initiation: The user inputs the code on a mobile device.
• Transmission: The request is sent to the mobile network.
• Processing: The network processes the request and accesses the necessary data or service.
• Response: The user receives a response on their screen usually in under a minute.
• No Internet Needed: This feature is especially critical for users in regions with limited internet access.

Section 3: Applications of USSD Codes

USSD codes serve a variety of sectors due to their simplicity and cost-effectiveness.

• Banking and Finance:
  • Balance inquiries
  • Mini statements
  • Fund transfers
• Telecommunications:
  • Checking remaining airtime/data
  • Purchasing additional minutes or data
• Customer Support:
  • Contacting customer service
  • Retrieving customer-specific information
• Mobile Payments:
  • Initiating mobile money transfers
  • Paying bills directly from a mobile device
