You can access all of the process modes of

Address Verification

from a single interface. You can enter up to 1000 addresses in batch and certified modes. In interactive mode and fast completion mode,

Address Verification

returns up to 100 suggestions. You enter a single address per request in interactive and fast completion modes.

Address Verification

has a flexible interface that enables you to access the latest

Address Verification

features without changing the WSDL. For example, the Web Service 4 interface defined enumerators for all parameters. Adding options to Web Service 4 meant modifying the interface. Later

Address Verification

interfaces define parameter names but not the parameter values, which are plain String values. In this way, you can add new values to the current parameters without changing the interface.

The current interface is the fourth iteration of the interface. The following URL contains the version identifier

v4

:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="https://validator5.addressdoctor.com/webservice5/

v4

/addressvalidation.asmx">

Address Verification

can use the multithreading capabilities of the

Address Verification

engine. Additionally,

Address Verification

benefits from improved processing speed.

Address Verification

provides you with objects for parameters and addresses in the same manner as the earlier Web Service 4 interface. The default call from

Address Verification

goes to the

process

web method. The objects have a structure that support the capabilities of the

Address Verification

version 5 library.
