Older Addresses in South Korea
In addition to the current version of a South Korea address, the reference data for South Korea stores any older, land lot-based version of the address. The reference data also stores any older, six-digit post code that applied to the address. Address Verification recognizes the older and newer versions of the address and can read and write any combination of new and old address and postcode data.
When you verify a South Korea address in batch or interactive mode, you retrieve a corresponding address ID value as an enrichment. If the address is not in the current format, you can enter the address ID in address code lookup mode to retrieve the current version of the address. The final character of the address ID indicates the format of the address. You can modify the address ID to retrieve a different combination of old and new address data.
The address ID identifies an address to house number level. If the address ID matches a single building at the current address, Address Verification returns the address with the building information in address code lookup mode. If the Address ID matches multiple buildings, Address Verification returns each address with the building information in address code lookup mode.
An older, land lot-based address might correspond to multiple current addresses. For example, the older address might identify a lot on which multiple buildings now stand. When you verify the older address in batch mode, Address Verification verifies the address and returns the address ID for the lot. When you enter the address ID in address code lookup mode and specify the current address data, Address Verification returns the address of every building on the lot. Each building-level address has a corresponding, unique address ID.
It follows that a land lot-based address can be valid with or without building information. When the address omits building information, Address Verification validates the address to house number level and returns the corresponding address ID. When the address includes building information, Address Verification validates the address to building level and returns the corresponding address ID.
Consider the following rules and guidelines when you verify older South Korea addresses:
If you set MatchingExtendedArchive to OFF, Address Verification considers only the current, street-based address and the current post code as valid. When MatchingExtendedArchive is OFF, Address Verification rejects or corrects outdated lot-based addresses.
If you set MatchingExtendedArchive to ON, Address Verification returns an Extended Element Result status of F for a lot-based address.
To retrieve the address ID, you must enable South Korea address enrichments and you must install the South Korea enrichment database.
