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: __ __ 강남구 대치3동 973-2번지 ㅇㅇ아파트 135-778
Fixed: 서울 강남구 대치3동 973-2번지 ㅇㅇ아파트 135-778
In this case, since there is only one combination of '강남구 대치3동' within Korea, the Postal Matcher can fill in the Level 1 value.
- Example 2 - Missing Level 2
-
Input: 서울 __ __ __ 대치3동 973-2번지 ㅇㅇ아파트135-778
Fixed: 서울 강남구 대치3동 973-2번지 ㅇㅇ아파트 135-778
In this case, since there is only one '대치3동' within '서울' and that being '강남구', the Postal Matcher is able to fill in the Level 2 value.
- Example 3 - Missing Level 3
-
Input: 서울 강남구 __ __ __ 973-2번지 ㅇㅇ아파트 135-778
Fixed: 서울 강남구 대치3동 973-2번지 ㅇㅇ아파트 135-778
In this case, although there can be many possible Level 3 values within '서울 강남구', and possibly multiple apartments with the name 'ㅇㅇ아파트', the postal code gives the Postal Matcher enough information to fill in '대치3동' as the Level 3 value.
Note: If the postal code information were not specified, the Postal Matcher would not be able to fill in the Level 3 value.
- Example 4 - Missing Level 4
-
In general, missing Level 4 values cannot be filled in, because these values refer to 'large-scale delivery sites' or 'apartment buildings' or `business buildings'. 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:서울 강남구 대치3동 973-2번지 ㅇㅇ아파트 ___-___
Fixed: 서울 강남구 대치3동 973-2번지 ㅇㅇ아파트 135-778
- Example 6 - Multiple Missing Elements
-
The Postal Matcher can also fill in more than one missing address element when it is logically feasible.
