Overview
Address validation determines if an address in question actually exists. The static address
validation service determines the potentially valid addresses that could match to the one entered,
essentially indicating the area of uncertainty associated with it. The AJAX address validation
indicates the valid values for each of the address components as they are entered, allowing a user
to iteratively increase the accuracy of thier input address.
If you encounter any problems or find any cases where the software fails, we would like to hear
about it so we can work to improve the quality of the services. Please
let us know.
