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:__ __ 台北市 士林區 和平路 80號111
Fixed: 台灣 台北市士林區 和平路 80號111
In this case, since there is only one Level 1 '台灣' within Taiwan, the Postal Matcher can fill in the Level 1 value.
- Example 2 - Missing Level 2
-
Input: 台灣 __ __ __ 士林區 和平路 80號111
Fixed: 台灣 台北市士林區 和平路 80號111
In this case, since there is only one '士林區' within '台灣' and that being '台北市', the Postal Matcher is able to fill in the Level 2 value.
- Example 3 - Missing Level 3
-
Input: 台灣 台北市 __ __ __ 和平路 80號111
Fixed: 台灣 台北市 士林區 和平路 80號111
In this case, although there can be many possible Level 3 values within '台灣 台北市', the postal code gives the Postal Matcher enough information to fill in '士林區' 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:台灣 台北市 士林區 和平路 80號 ___
Fixed: 台灣 台北市 士林區 和平路 80號111
- Example 6 - Multiple Missing Elements
-
The Postal Matcher can also fill in more than one missing address element when it is logically feasible.
