Regulatory Framework for SMS in South Korea

The telecommunications and data protection landscape in South Korea is regulated by KCC (Korea Communications Commission). Compliance with local A2P SMS regulations is not optional — non-compliant traffic is actively filtered at the carrier level and can result in route blocks, financial penalties, and reputational damage.

The Act on Promotion of Information and Communications Network Utilization governs A2P SMS. Explicit opt-in is required. Sender identification is mandatory for commercial messages.
