Enrichments for Japan Addresses

Enrichments for Japan Addresses

You can configure Informatica Address Verification to add enrichments to valid Japan addresses. To enable address enrichments for Japan, you must license and install the relevant address databases for Japan and include the corresponding unlock code in
Address Verification offers the following enrichments for Japan:

Choumei Aza Codes

A Choumei Aza code is an 11-digit string that represents an address to delivery-point level in Japan. When Japan Post updates the address information for a delivery point, Japan Post also issues a new Choumei Aza code for the delivery point. Therefore, a delivery point might have a current address and one or more legacy addresses and a corresponding set of current and legacy Choumei Aza codes.
You can submit a Japan address in batch or interactive mode and return one or more Choumei Aza codes that represent different versions of the address. You can submit a Choumei Aza code in address code lookup mode to obtain the version of the address that the code identifies.
Address Verification returns the following types of Choumei Aza code:
The code that corresponds directly to the validated version of the address that you submit.
The code that corresponds to the next iteration of the input address that you submit. For example, if you enter the first or oldest version of the address, the NEW_CHOUMEI_AZA_CODE value that Address Verification returns represents the second version of the address.
The code that corresponds to the current version of the address that you submit.
The Japan reference data contains the current version of an address and two older versions. You have the first or oldest version of the address. You select the Japan enrichments, and you submit the address in batch mode. Address Verification verifies the address and returns the Choumei Aza code enrichments. You submit the CURRENT_CHOUMEI_AZA_CODE value in address code lookup mode. Address Verification returns the current version of the address.
The NEW_CHOUMEI_AZA_CODE returns the Choumei Aza code for the update that directly followed the address that you submitted. You can rerun the steps with the NEW_CHOUMEI_AZA_CODE value to find each version of the address in the reference data.
To read or write the Choumei Aza codes for earlier versions of an address, enable the
attribute of the
element in
in addition to the address enrichment settings. For more information about Choumei Aza codes and legacy Japan addresses, see Using the Extended Archives to Check Addresses.

Gaiku Codes

A Gaiku code is a four-digit code that identifies a city block in Japan.
Append the Gaiku code to a current Choumei Aza code to create a 15-digit string that you can submit in address code lookup mode to find an address.
