A South Korea address can combine current and non-current post codes with street-based and lot-based address information. A lot-based address might use an older or newer post code, and a street-based address might use an older or newer post code. Additionally, a lot-based address might match multiple current addresses if multiple buildings stand on the lot. You can use Address Verification to obtain different combinations of the address and the post code. If the address corresponds to multiple current addresses, you can use Address Verification to return all of the current address. The steps that you take depend on the combination of address data values in the input address and the versions of the address data that you require.

The following table shows the different types of address that you can verify:

When you verify an address in batch or interactive mode, Address Verification returns an address ID with the final character A, B, C, or D. The final character identifies the types of information that the address contains.

The final character identifies the following combinations:

To obtain a different combination of address data, replace the final character in the address ID value with the character that represents the combination that you require. Then enter the modified address ID in address code lookup mode.

When you specify B or D as the final character, Address Verification returns the address of the lot on which the building is located. A lot-based address does not contain building information, and Address Verification can validate a lot-based address without building information.

When you specify A or C as the final character, Address Verification returns the current version of the address, including any applicable building information. If you update the final character in the address ID of a lot-based address to A or C, Address Verification returns multiple addresses if multiple buildings stand on the lot. You can submit each address with building information to retrieve a unique address ID for the address.

In a Hangul address, Address Verification parses lot number identifiers and lot sub-number identifiers to the fields that include the lot number and lot sub-number data.

For example, the following address element includes the 번지 or

bunji

lot number identifier:

Address Verification parses 20번지 to the house number field.
