Address Certification Considerations
The Address Validator transformation can indicate if an address contains the data required by the certification standards of national mail carriers. The standards require that a software application validates address accuracy and prepares address records in the correct format for automated mail sorting and delivery. If you use the data in a certified validation process, update the address reference data files once a month.
If you use United States or Canadian address reference data to certify address records to the Coding Accuracy Software System (CASS) or Software Evaluation and Recognition Program (SERP) standard, you must use reference data that is no more than 60 days old.
