KakaoTalk, often shortened to KaTalk, is the messaging app almost every person in Korea uses, and its role extends well beyond casual chatting into practical infrastructure: exchanging work contacts, sending money through KakaoPay, receiving hospital or reservation reminders, and even verifying identity for certain services. Because so much everyday and professional communication assumes you're reachable on KakaoTalk, not having an account can genuinely make coordinating with people in Korea difficult.
WhatsApp and WeChat are dominant messaging platforms in other parts of the world — WhatsApp broadly internationally and WeChat in China — but neither carries the same near-universal adoption or integrated services within Korea that KakaoTalk does.
KakaoTalk's dominance has turned it into a platform in its own right, bundling messaging, payments, ride-hailing, banking, and even government-linked identity verification under one app, which is part of why setting it up is often one of the very first things new residents are advised to do.
