40 million Americans change their address each year. As your database ages, you will be wasting valuable marketing dollars by mailing to these addresses - And to capture discounted postage rates, the Post Office requires you NCOA and CASS certify your lists!

• National Change of Address

  
  Updates your list with the 48 months of change of address information files with the USPS. This processing is required for automation mail discounts.

• CASS

  
  This system improves the accuracy of 5-digit ZIP, ZIP+4, carrier route, and delivery point barcodes, and is required for automation mail discounts.

• DSF

  
  Delivery Sequence File - Checks mailing lists against the complete, exact address for every point served by the USPS. Detects incomplete addresses such as missing apartment numbers.

  Flags records in your list where consumers have indicated that they do not wish to receive advertising mail at home. Members of the Direct Marketing Association must run all lists through this process to comply with membership requirements.

• LACS
