What Does Address Validation Offer?
Our USPS CASS Certified™ Address Validation service improves internal mail processes and delivery rates by standardizing contact records against USPS data and flagging for vacancy, addresses returning mail, and general delivery addresses. Our industry-leading GetBestMatches operation now combines Delivery Point Validation (DPV), SuiteLink, and Residential Delivery Indicator (RDI) into one robust API call to our USPS CASS Certified™ database engine.
Delivery Point Validation (DPV)
The DPV 1-4 codes are our way of indicating the deliverability of an address. A quick glance at the DPV code can tell you if an address is deliverable according to the USPS.
DPV can be broken down into the 4 following codes, and their subsequent descriptions:
1: Yes, the input record is a valid mailing address
2: No, the input record is not in the DPV database of valid mailing addresses
3: The apartment or rural route box number is not valid, although the house number or rural route is valid
4: The input record is a valid mailing address, but is missing the apartment or rural route box number
The DOTS Address Validation 3 service has the ability to correct and/or append suite information to an address. Through the use of business names, the service will try to find or append the proper suite information. SuiteLink provides an added level of accuracy to Business to Business relationships by ensuring the proper address and suite information is included in your validated data.
Residential Delivery Indicator (RDI)
The Residential Delivery Indicator enables you to know if an address is residential. This is often important if you are looking for targeted marketing (Business to Consumer). By knowing your target address’s delivery type you can make more informed business decisions.
The Coding Accuracy Support System (CASS) enables the United States Postal Service (USPS) to evaluate the accuracy of software that corrects and matches street addresses. It is important because it ensures that our validation system doesn’t make far-reaching changes to your input address. We comply with the CASS regulations and thus, the validated address and additional information that is returned to you actually pertains to the original input address. A company that doesn’t comply with the CASS regulations could easily take your input address and make a change to it that completely changes the intended location. In doing so, your data would be rendered effectively useless. The DOTS Address Validation 3 service is CASS compliant and any changes that may be made will pertain to the proper address.
