Postal Relevance

Postal Relevance

You can use the PostalRelevance property value to identify the address elements that are relevant to an address according to the local postal guidelines. Address Verification returns a discrete postal relevance value for every address data element.
The following table describes the postal relevance values:
Value
Description
2
Element mandatory. The address element is relevant.
1
Element optional. The address might be valid without the element.
0
Element not used in the postal format. Address element is not relevant.
All address elements with an element relevance value of 2 must be present for the local postal authority to consider an address valid. Element relevance value might vary from address to address for countries with different address types, such as rural address and metropolitan addressing. Furthermore, address elements that have actually been validated against reference data might override the default element relevance value defined for that address element.
Element relevance values are available only for addresses with a process status value of C or V in batch and interactive modes or I values in the interactive mode. Other element-level codes such as match status, result status, and extended result status always return a value regardless of the process status.
