Validating an address with CASS™ and DPV® data

A lot goes into confirming that an address is valid. For the United States Postal Service (USPS), there are several pieces of information needed to verify an address. When you use address validation software, it checks the information entered against USPS’s database and requirements. A couple of terms to know when it comes to address validation are CASS and DPV. The Coding Accuracy Support System (CASS) is a certification process used by USPS to evaluate the accuracy of address correction/matching software. Delivery Point Validation (DPV), which is one of the USPS-sourced files included in CASS data, is used to check the status of a specific address within the United States.

How can I use address verification to identify business versus residential addresses?

The costs of shipping can vary based on the type of address to which you’re sending. In fact, private shippers may charge an address correction fee if an address has been wrongly identified as a residence or business.

We incorporate two datasets into our address verification solutions to help businesses get a better idea of what kind of address they are shipping to (business or residential), and that helps them make more cost effective shipping decisions.

What lists does ISTWatch use?

It is important for companies to comply with the Office of Foreign Assets Control (OFAC) regulations. Failure to do so can result in fines and even imprisonment. Experian Data Quality offers an OFAC-compliant software called ISTwatch, which allows companies to search and match names against a number of compliance and global watch lists.
