Enrichments for Japan addresses

You can configure a verifier to add enrichments to valid Japan addresses.

A verifier offers the following enrichments for Japan:

Choumei Aza Code JP

New Choumei Aza Code JP

Current Choumei Aza Code JP

Gaiku Code

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.

A verifier returns the following types of Choumei Aza code:

Choumei Aza Code JP: The code that corresponds directly to the validated version of the address that you submit.
New Choumei Aza Code JP: 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 JP value that the verifier returns represents the second version of the address.
Current Choumei Aza Code JP: The code that corresponds to the current version of the address that you submit.

Example: 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. A verifier verifies the address and returns the Choumei Aza code enrichments.; The New Choumei Aza Code JP 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 JP value to find each version of the address in the reference data.
