Explanation of QAS Match Codes versus SendRight Address Classification

QAS Batch cleans the address records in your database by verifying them against the official postally-correct address files for the relevant country. Cleaned
records are assigned a match result, based on the accuracy of the original address compared to the suggested result.

In addition through its SendRight Certification, QAS Batch is able to produce a SendRight Statement of Accuracy (SOA) which can be used for bulk mailing
discounts.

The match categories used within QAS Batch ie Verified, Good Match, Tentative etc) are universal across all of the available QAS datasets and are
completely distinct from the SOA classifications (Unique, Base) used for SendRight scoring.

QAS Batch is designed to match and improve data quality, whereas an SOA % is simply a score comparing the input address to the NZ PAF.

In the following pages we will explain these differences in further detail.

1.       QAS Batch Match Categories (Match Code Identifier)




High Confidence Matches (Automatically committed by default)

         Verified Correct (R9)
         The supplied address has been verified as effectively correct, although minor corrections or formatting changes may have been applied.



         Good Full Match (R9)
         A full (i.e. complete to the delivery point) address match has been located. Batch is confident in its choice of match, despite differences in content
         between supplied and matched addresses.

                                                                                             Explanation of QAS Match Codes versus SendRight Address Classification
Low Confidence Matches (Requiring manual interactive cleaning)

         Tentative Full Match (R5)
         Batch has found a full address match, but the overall differences between the supplied and matched address elements are overly significant for Batch
         to have complete confidence in the address allocated.



         Poor Full Match (R0)
         Batch has found a full address match, but the overall differences between the supplied and matched address elements are significant and Batch only
         has very low confidence in the address allocated.



         Multiple Match ([MN])
         Batch has found several addresses that match equally to the one supplied. It cannot determine which of the addresses is most likely, so it is unable
         to return any of those it has located.



         Partial Match ([OP])
         Batch has not been able to find a full or premise level address match, but has found a partial reference match by skipping any leading address
         information that could not be matched. Partial matches are usually assigned when the provided street number is missing on input, or does not exist
         on the PAF.



         Unmatched ([ABDKL])
         Batch was unable to successfully derive a match for the supplied address. The input fields may have been blank, contained only a postcode, or
         contained information that does not match any addresses on the data files.

                                                                                             Explanation of QAS Match Codes versus SendRight Address Classification
         Foreign Address ([CD])
         The input address contains a country name, but that country database is not in use with QAS Batch. Records in this category have been assigned a
         C match type. If the input address does not contain a country name but it relates to a country not installed and in use with Batch then an Unmatched
         type is allocated.

                                                                                            Explanation of QAS Match Codes versus SendRight Address Classification
2.        SendRight Address Classification

In order to receive bulk mail discounts from the New Zealand Post under the SendRight Address Accuracy Programme, addresses must be validated against
the New Zealand Post’s Postal Address File (PAF). As part of the SendRight programme, a Statement of Accuracy (SOA) report and Production Log must
also be obtained.

The SendRight Address Classification is based purely on the input address and is designed to simply categorise it into one of four main categories (Base,
Unique, Invalid or Excluded) based on the direct correlation with the NZ Post’s PAF File.

These categorised matches are used to determine the SOA %.


SOA Calculation

The SOA % is calculated as follows:

     SOA % = 100 * (UniqueMatches + BaseMatches) / (TotalProcessed - (ExcludedRecords))


Examples of each classification and the associated match codes are explained in detail on the subsequent pages.

Unique Address Match
The supplied input address unambiguously
matches one address record in the PAF.

Base Address Match
The supplied input address matches to any two or
more address records in the PAF that have the same
value in all of the address elements according to the
following table

Urban addresses
Street Number without Street Alpha
Street Name
Street Type
Street Direction
Town/City
Postcode

Rural addresses
Street Number without Street Alpha
Street Name
Street Type
Street Direction
Town/City (Mailtown)
Postcode

Example:
The following addresses in the PAF have the same
Base Address (6 SMITH STREET, THORNDON…)
  FLAT 1, 6 SMITH STREET, THORNDON 6011…
  FLAT 2, 6 SMITH STREET, THORNDON 6011…
  6A SMITH STREET, THORNDON 6011…
  6B SMITH STREET, THORNDON 6011…

Invalid Address Match
The supplied input address record is not
identified as a Unique or Base Address match.

An input address is invalid if it:
a) Contains any postal address element other
than those permitted for its address type by
Rule 7 (see Appendix A);
b) Contains any incorrectly positioned address
or non-address elements;
c) Contains more than one value for the same
element; or
d) Contains a ranged street number.

Excluded Address
The following address records may be excluded from
the SOA calculation:

    •    Un-numbered rural addresses (rural
         addresses where no street number has been
         allocated). This applies until 30 June 2009
    •    Post Restante
    •    Overseas/international
    •    Private Bags with no number
