Business Registration Inquiry is an app that allows you to easily check the status of a business and verify the authenticity of business information by entering a business registration number.

Based on the National Tax Service's Public Data API, you can look up the tax type, business status, and closure date associated with the business registration number. You can also verify whether the entered information matches the actual business details by entering the business registration number, opening date, and representative name together.

Since you can perform a lookup immediately by entering only the necessary information without complex procedures, it can be utilized for verifying the business before a transaction, checking before issuing a tax invoice, reviewing business partner information, and checking business registration numbers for internal business use.
