Introduction

DOTS Address Validation 3 US (“AV3”) is a new version of our Address Validation and Address Validation 2 Web services. This service utilizes the latest .Net Framework, WCF, and can be used as a RESTful service or with SOAP. AV3 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.

AV3 can provide instant address verification and correction to websites or enhancement to contact lists.  However, the output from AV3 must be considered carefully before the existence or non-existence of an address is decided.

Integration Basics

Integrating AV3 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.

AV3 is a public XML web service that supports SOAP, POST and GET operations, using RESTful paradigms or simple HTTP transport calls.

Important Notes!

  1. This XML is the definition of the web service, meaning its inputs, outputs, operations, and the like.  Most likely, you will have another tool read this WSDL and make the operations available to you in your application.  Whenever your utilities or IDE asks for a WSDL path to AV3, you can provide this one.
  2. SOAP is done via POST, only with special XML markup in the post-body.

Every web service has operations that it offers to subscribers – methods that do different work and return different output.  Examining the link above, you will notice several of these operations available, which are described in detail later on.
