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.

If you are an existing client and are using the previous version of this service then please click on the following link.

Important Note!
SOAP is done via POST, only with special XML markup in the post-body

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.
