Customer Care supports MSAG (Master Street Address Guide) validation on service addresses. This functionality requires some setup by IDI and service providers.
(More)
Some setup is required specifically to use MSAG Validation in Customer Care, and some is required in general – whether you use it in Customer Care or Desktop Client.
To use in Customer Care:
Enable MSAG validation in Customer Care – This is done via MANAGE > Settings > General > Enable MSAG Validation.

Set up user roles and permissions - Users responsible for MSAG validation in Customer Care must be assigned a role with Manage Service Address permission in the Security web module.
The following is required regardless of where you use MSAG validation:
Add an MSAG validation node in Config Console – This must be completed by an authorized IDI associate on your behalf.
Manage MSAG providers – This is done via Admin Console Data Management as described in Desktop Online Help.
Upload MSAG files - MSAG providers generate the addresses that are loaded into the MSAG table. Each MSAG provider you use has a set of records containing location information for the respective Service Addresses. Uploading these files is done via Desktop Client Applications > BackOffice Management > MSAG Management > MSAG File Upload. See Desktop Online Help.
Performing MSAG Validation
In Customer Care, service addresses are managed on an account via the customer menu - Services > Service Addresses option.

The Service Addresses page displays existing service addresses for the account.

From here you can create new service addresses, edit an existing address, or add a service address to the account. When MSAG validation is enabled, you can perform this validation when you add a service address to the account or edit an existing service address. For existing service addresses, when you click on one in the left panel, you can see whether the address has been MSAG validated.

To fix a Not MSAG Validated address, click EDIT and enter MSAG Validation information as required.

MSAG providers (Provider drop-down menu) are managed via the Admin Console Data Management MSAG provider table. The content of this table populates the Provider drop-down menu. The Community and County menus are populated based on MSAG information in the IDI platform.
On saving, if the information is correct the validated status will be indicated.

Click ADD to add a service address to the account and validate the address. This displays basically the same dialog as shown above.
