Address Verification in OEDQ is comprised of the Address Verification API, and a Global Knowledge Repository (also known as Postal Address File).
A subscription to a Postal Address File must be purchased directly from a provider, and Oracle's prefered partner for this is Loqate, (http://www.loqate.com/).
See explanation here for details: https://blogs.oracle.com/mdm/entry/enterprise_data_quality_integration_ready
The Address Verification and Standardization service uses EDQ Address Verification (an OEM of Loqate software) to verify and clean addresses in either real-time or batch. The Address Verification processor is wrapped in an EDQ process – this adds significant capabilities over calling the underlying Address Verification API directly, specifically:
- Country-specific thresholds to determine when to accept the verification result (and therefore to change the input address) based on the confidence level of the API
- Optimization of address verification by pre-standardizing data where required
- Formatting of output addresses into the input address fields normally used by applications
- Adding descriptions of the address verification and geocoding return codes
The process can then be used to provide real-time and batch address cleansing in any application; such as a simple web page calling address cleaning and geocoding as part of a check on individual data.

Thank you Oliver. I am now proceeding as your comments.
