Frequently Asked Questions

Q. Can I see the business owner's name?
Due to privacy laws in South Korea, private websites cannot directly display owner names from a database. However, by clicking the [FTC Business Info] button, you can verify the registered owner and address via the official government portal.
Q. How do I know if it's a Corporation?
The middle two digits (XXX-XX-XXXXX) indicate the entity type:
• 01~79: Individual / Sole Proprietor
• 81~86: For-profit Corporation (Main/Branch)
• 80, 89, 90: Tax-exempt or Non-profit Organization
