Effective on August 1, 2015, South Korea’s existing 6-digit postal codes have been replaced with a new set of 5-digit postal codes. As a result, the new GAV tables will change to the new format and TSS will convert the 6-digit postal codes to the 5-digit postal codes in order to facilitate a smooth transition.
When you use the new table, you will see the following differences in the output attributes:
Postal codes will be updated to the new 5-digit format.
The pr_level3 attribute will be blank for major cities. Provinces and other areas will still receive pr_level3 if applicable.
Street name will be filled in the pr_level4 attribute.
All grid type (block/bunji) attributes will be blank. Those attributes are:
-
pr_block_number
-
pr_block_number_display_full
-
pr_sub_block_number
-
