This is a bit different. It's matching what you have versus what a 3rd party has. You have no control over the third party.
We do use SmartyStreets to normalize the address before submitting, but the 3rd party uses something else. Also, address correction is a weird space. UPS, for example, delivers to many places that the USPS does not. Rural communities are especially tricky. UPS, Fedex, and USPS disagree on things like "Rural Route 24" vs "State Route 24" versus "Arizona Route 24".
