Developer Guide for DOTS Phone Exchange - Instantly validate domestic phone numbers using the most accurate phone intelligence available to improve contact rates and compliance adherence.
Our domestic (USA/Canada) Phone Exchange service returns comprehensive carrier and exchange information, including ported status, SMS and MMS details and identifies high-risk VOIP and prepay phones.
Our international Phone Exchange service validates and formats phone numbers for international direct dialing, while returning line type, country code and geocoding information.
NOTE: The DOTS Phone Exchange 2 web service has recently been updated, and as such some of the older operations have been deprecated. If you are still currently using the older operations of the service, you can refer to the developer's guide below for information concerning integration, inputs and outputs for the deprecated operations.

Frequently Asked Questions
This is a list of some of the questions we hear more often that you can reference and get answers on right away.
Integration of DOTS Phone Exchange 2 into user applications is generally a straightforward process. For common programming platforms, such as ASP, ASP.NET, ColdFusion, PHP, etc., Service Objects will likely have sample code available online:
If the code you seek is not available online, you can ask Service Objects to build a custom example for you. Email firstname.lastname@example.org for more details.
Web Service Structure
Web services provide a standard interface to encapsulate tricky business logic. They allow simple integration of applications via the web. Service Objects has followed web services best practices and come up with some of its own standards to ensure that its web services are as easy to integrate and as accessible as possible.
The host path or physical location of the web service is here:
The location of the WSDL, or Web Service Definition Language document, is here (This is also accessible via the "Service Definition" link on the web service page.):
The WSDL is an XML document that defines the interaction 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 via some type of proxy class. Whenever your utilities or IDE asks for a WSDL path, you can provide this one.
Every web service has operations that it offers to subscribers. These operations, also called methods, contain different functionality and return different outputs. DOTS Phone Exchange 2 has one operation, it will be described in detail later in this document.
