No, really. What does DOTS Address Validation do?
Ok, fine. A malformed and/or incomplete address is sent to our service, we perform preliminary checks, then run it through a CASS Certified engine which molds the address into the USPS standardized format, corrects the parts of the address that were incorrect, verifies that the address is deliverable, and appends additional useful data such as the Carrier Route, Zip+4, and DPV Barcode Digits (if using the ValidateAddressWithDPV operation).
