Short after introducing the new address system called "Road Name Address," the Republic of Korea has also reformed the postal code system into the so-called "State Basic District System." Addresses with the new postal codes are freely available in bulk on the site of "Road Name Address," but the dataset does not include coordinates.

The dataset which meets the minimum criteria can be found on the Website of the National Spatial Information Clearinghouse (NSIC). However, the dataset is not publicly available requesting the registration. However, people can freely download in bulk daily changes of address data with its coordinates on the Korean Website of "Road Name Address."

Reviewer comments

The webpage does not seem to work from outside Rep of Korea. "National Spatial Data Distribution System is only available in Korea."
