Primary address information is specific information like building number and street in an address.
Correct address information sounds easy enough, but it can be a continual challenge for organizations to collect. Over the phone, "Fourteen Parker Circle" sounds similar to "Forty Harper Circle", and online, 123 Main could actually be 12 Main.
Address verification software recognizes what streets and even house/building numbers are acceptable address information and prevents the entry of incorrect information.
A typedown functionality also shows users what are acceptable numbers, and a picklist makes choosing accurate information simple and quick.
