The Postal Service is stepping up its efforts to reduce undeliverable mail. With AddressFinder, Blackbaud returns a dated CASS_AddressFinderSummary.pdf that shows how many records were submitted and updated. This report may be used for proof that the data was screened for NCOA updates. It is downloaded with your AddressFinder update.  It is recommended to run AddressFinder every 95 days to always stay compliant with the Move Update Standard.
