There are three ways for participating companies to connect to the CBSV system. As a CBSV company you may use one or all three ways. It is your choice.

Real Time Response Web Service

The CBSV Web Service is designed to support interoperable machine-to-machine interaction over the Internet. This provides instantaneous response and handles volumes easily. With the Web Service, companies create their own, unique interface with CBSV. If you are a developer who works for a company that plans to access CBSV through a Web Service, it is recommended that you refer to our CBSV Web Service Documents.

The Web Service Description Language (WSDL) for CBSV is documented in the Interface Specification for CBSV Web Service document. The Web Services Description Language is an XML-based language that provides a model for describing Web services. WSDL is often used in combination with SOAP and XML Schema to provide Web services over the Internet. A client program connecting to a Web service can read the WSDL to determine the functions that are available on the server.

Real Time Response Internet Online

CBSV allows you to request verification of up to 10 names and SSNs at a time, online, and receive instantaneous results. There is no limit to the number of times the CBSV Verification web page may be used within a session or within a day. The CBSV Online Verification service requires you to have Internet access and a Web browser, such as Internet Explorer or FireFox. Your browser version must allow ‘cookies’ (files store temporarily on your computer) and have 128-bit encryption.

Batch File Process

CBSV allows you to request Name and SSN verifications through overnight batch (electronic file) submissions. The batch file process requires you to have Internet access and a Web browser, such as Internet Explorer or FireFox. Your browser version must allow ‘cookies’ (files store temporarily on your computer) and have 128-bit encryption.

Each of these three ways to connect to CBSV is described further in CBSV User Guide- 10/4/08 Edition Get Adobe Reader
