If the address data is incomplete, the Postal Matcher can fill in relevant information from the rest of the geographic level and postal code data. For example, an input address data may be missing the Level 1 geographic level value. Assuming that the rest of the geographic data in combination are unique within the national addressing system, the Postal Matcher can fill in the correct Level 1 value.
- Example 1 - Missing Level 1
-
Input: __ __ __千代田区丸の内1 - 2 - 3 日本ビル101 号1000005
Fixed: 東京都千代田区丸の内1 - 2 - 3 日本ビル101 号1000005
In this case, since there is only one combination of '千代田区丸の内' within Japan, the Postal Matcher can fill in the Level 1 value.
- Example 2 - Missing Level 2
-
Input:東京都 __ __ __ 丸の内1 - 2 - 3 日本ビル101 号1000005
Fixed: 東京都千代田区丸の内 1 - 2 - 3 日本ビル101 号1000005
In this case, since there is only one '丸の内' within '東京都' and that being '千代田区', the Postal Matcher is able to fill in the Level 2 value.
- Example 3 - Missing Level 3
-
Input:東京都千代田区 __ __ __ 1 - 2 - 3 日本ビル101 号 1000005
Fixed: 東京都千代田区丸の内 1 - 2 - 3 日本ビル101 号1000005
In this case, although there can be many possible Level 3 values within '東京都千代田区', the postal code gives the Postal Matcher enough information to fill in '丸の内' as the Level 3 value.
- Example 4 - Missing Level 4
-
In general, missing Level 4 values cannot be filled in, because these values refer to 'building names' or 'building #'. Only a limited number of these buildings are catalogued by the national postal authority and thus cannot be verified with precision.
- Example 5 - Missing Postcode
-
Input:東京都千代田区丸の内 1 - 2 - 3 日本ビル101 号__ __ __
Fixed: 東京都千代田区丸の内 1 - 2 - 3 日本ビル101 号1000005
- Example 6 - Multiple Missing Elements
-
The Postal Matcher can also fill in more than one missing address element when it is logically feasible.
