Introduction

DOTS Address Validation 4 US (“AV4”) is a new version of our Address Validation and Address Validation 3 Web services. This service utilizes the latest .Net Framework, WCF, and can be used as a RESTful service. AV4 is designed to take an unstandardized address, validate it against the latest USPS data, and return standardized, deliverable addresses. The service provides corrected information such as the correct street location and zip plus four code, along with parsed address tokens, such as the PMB box number, pre- and post-directionals, county and state codes, and much more.

AV4 can provide instant address verification and correction to websites or enhancement to contact lists.  However, the output from AV4 must be considered carefully before the existence or non-existence of an address is decided. AV4 can be used in three modes. Mode 1, is for doing the standard validation as it always has with USPS datasets and expert address validation techniques. Mode 2, uses standard rules plus aggregated non-USPS datasets. And, mode 3, enhanced rules plus name and phone assisted address nudging, using proprietary data.

Integration Basics

Integrating AV4 into your application should be easy and straightforward. If you are using a common platform, Service Objects may already have sample code built that you can use.

However, if you are using a common platform that does not already have sample code, you can ask Service Objects to build you an example. Email support@serviceobjects.com for more details.


Web Service Structure:

Web services are methods that integrate with other applications via the web, and encapsulate tricky business logic. Web services are too large of a topic to cover in this document, but Service Objects has developed its web services to be as easy to integrate and as accessible as possible.
