Bizno is a Korean business information search service designed to help users find and check details about registered businesses. Its database covers millions of business registrations, and the site displays information such as business names, corporate registration numbers, addresses, and business categories. Users can search by business registration number, corporate registration number, company name, telephone number, or representative’s name, and can browse businesses by region.

Bizno also provides a business-status lookup connected in real time with the National Tax Service’s Hometax system, including checks for businesses that have closed or suspended operations. The site presents recently registered and updated businesses, as well as examples of companies receiving real-time searches. For organizations seeking to integrate business information searches into their own services, Bizno lists an API offering.

The platform also includes customer inquiries and correction requests, allowing users to contact the service about search information. Bizno cautions that unauthorized collection of its database may infringe copyright or violate applicable information and communications laws
