Can I use the Perfect Address SDK in an interactive application?
Yes. The Perfect Address SDK can be used with either batch or interactive applications, but it includes special functions designed just for interactive applications. These interactive functions are not permitted under the USPS’s CASS rules, and therefore are not available in other products. If the DLL finds no exact match, it applies the “one component failure rule” in an attempt to find an address match. Using this rule, the DLL often finds multiple addresses which satisfy the address matching criteria. However, the USPS address matching rules prohibit the DLL from making a “guess” as to which address is correct.
