Hi guys , Today i am going to show you street level address validation of USPS/Endecia. Since Endecia already have provided us very good services so i have used them. here is the sample code.
Here i am taking three parameters as input.
1. Address(Street level).
2. City
3. State
Now on my web form i have taken three textboxes like below.
<form id="form1" runat="server">
<div style="width:500px; margin-top:10px;">
<h2>USPS/Endecia Address Validation</h2>
</div>
