What Is a USSD Code?

USSD codes, or Unstructured Supplementary Service Data codes, are simple, text-based commands you dial on your phone to interact with your mobile network provider.
They don’t require internet access and work on all types of phones—smartphones and basic models alike.

  • USSD codes usually start with an asterisk (*) and end with a hash (#), for example, *123#.
  • They provide menu-based prompts for services like checking balances, purchasing bundles, or changing account details.
  • USSD is widely used in South Africa because of its simplicity and compatibility with all handsets[3].

“USSD stands for Unstructured Supplementary Service Data and is a protocol used by the Global System for Mobile (GSM) communications cellphones to communicate with service providers’ computers.”—Strategix
