The Verifier transformation adds a verifier asset to a mapping.
The Verifier transformation performs the following operations on input address data:
The transformation compares the address records in the source data to address reference data.
It fixes errors and completes partial address records. To fix an address, the transformation must find a positive match with an address in the reference data. The transformation copies the required data elements from the address reference data to the address records.
It writes output addresses in the format that the
verifier asset specifies. You define a verifier asset to create address records that
suit your business needs and that conform to the structure that the mail carrier
requires.
It can report on the deliverable status of each address and the nature of any error or ambiguity that the address contains.
It can provide suggestions for any ambiguous or incomplete address.
For more information about the types of address information that the Verifier transformation
can read and write, including address status information, see

.
A Verifier transformation is similar to a Mapplet transformation, as it allows you to add
address verification logic that you created elsewhere to a mapping. Like mapplets,
verifiers are reusable assets.
You can create a verifer asset through the transformation properties, or you can create
the asset separately in
Data Integration
or
Data Quality
.
A verifier asset defines a template for input and output address data that you can
connect to the input and output fields on the Verifier transformation. Connect the
fields in your source data or in upstream transformations to the corresponding input
ports on the Verifier transformation. Connect the output ports on the Verifier
transformation to downstream transformations in the mapping or to the mapping target.
A Verifier transformation shows incoming and outgoing fields. It doesn't display the address
data that the verifier contains or allow to you edit the verifier. To edit the verifier,
open the asset.
