Our History
1998
Our journey began with the launch of a platform providing postal code information for China.
2011
Recognizing the need for comprehensive postal and administrative data in South Korea, we established kor.youbianku.com. This platform was dedicated to offering detailed information on South Korea's administrative divisions and postal codes, catering to both Korean and international users.
2015
A significant milestone occurred when South Korea transitioned from a six-digit to a five-digit postal code system. In response, we restructured our database to accommodate this change, ensuring that users could access both the new and old postal code formats. Historical data was preserved and made accessible through old.kor.youbianku.com.
2024
We undertook a major upgrade of our website, expanding our database to include extensive road address information. This enhancement aimed to provide users with the most comprehensive and accurate data available. Additionally, the website's design and structure were modernized to improve user experience and accessibility.
2025
In response to user demand, we developed the Korean Old-New Postal Code Conversion Tool. This tool allows users to seamlessly convert between the current five-digit and the former six-digit postal codes, facilitating easier navigation and understanding of address information.
