Company Overview

KT Corporation (KT) is a South Korean telecommunications and digital platform company headquartered in Seoul, South Korea. Originally established as the state-owned national telecom operator, KT provides fixed-line telecommunications, mobile communications, broadband internet, IPTV, cloud computing, artificial intelligence (AI), financial technology infrastructure, and enterprise digital transformation services. The company operates primarily in the telecommunications and information and communications technology (ICT) industries, with revenue driven by wireless subscriptions, broadband and media services, enterprise networking, data centers, cloud platforms, and digital business solutions.

KT serves consumer, enterprise, and public-sector customers across South Korea while maintaining selected international operations through subsidiaries and network partnerships. The company has positioned itself as an integrated “DIGICO” platform business, combining telecommunications infrastructure with AI, cloud, media, and financial services capabilities. KT’s historical advantage stems from its nationwide wired and wireless infrastructure, extensive fiber-optic networks, established enterprise customer base, and leadership in South Korea’s advanced broadband and 5G markets. Founded in 1981 as Korea Telecom Authority and later privatized in stages beginning in the late 1990s and early 2000s, KT evolved from a traditional fixed-line carrier into a diversified ICT and digital services provider.
