Returns parsed and validated address elements including Delivery Point Validation (DPV), Residential Delivery Indicator (RDI), and Suite data. GetBestMatches will attempt to validate the input address against a CASS approved engine, and make corrections where possible. Multiple address candidates may be returned if a definitive decision cannot be made by the service.
