CASS (Coding Accuracy Support System)
The term CASS is widely used by the USPS when they refer to the verification status of an address list. In order for an address list to receive CASS certification, the list must be checked against the USPS Address Matching System (AMS) CD-ROM, a match must be found for each address and the correct 25-digit Delivery Point ZIP code and corresponding barcode must be added. Only addresses with the Delivery Point ZIP code and barcode are eligible for automation bulk mailing rates. A mailing list must undergo address verification every six months (every three months for Carrier Route mailings) and is particularly important to mailers because of the difference between “automation” and “non-automation” mailing rates, which is about five cents per piece.
PAVE (Presort Accuracy Verification and Evaluation)
This is a voluntary program in which the U.S. Postal Service provides testing for presort software and hardware to determine their accuracy in sorting address information and in producing standardized supporting documentation. Presorting is the process of arranging your mail so that pieces going to the same area are bundled together. This allows for the mail to bypass one or more processes once it enters the mailstream. The USPS is thus able to skip certain sortations and process your mail more quickly and less expensively. The savings are passed on to you in the form of lower rates and faster processing. In general, the more levels of sorting you perform, the lower the cost of postage.
NCOA (National Change of Address)
This is a process that matches names and addresses on your mailing list to changes of address filed by relocating postal customers. When the name and address information on your mailing list matches the name and address information on the NCOA file, a new address will be returned. NCOA contains around 48 months of permanent address changes that are updated weekly. The file is maintained by the U.S. Postal Service and is licensed to vendors.
The turnaround time for NCOA processing is about 24 hours, but the file may be processed the same day if we receive it early in the day.
NES (Nixie Elimination Service)
A service that applies footnotes indicating why an authorized NCOA match could not be made to the input address. The footnotes help you analyze your records to determine the need for additional action such as a special mailing, special handling or elimination from the list. e.g. NES footnote “B” indicates a potential move; NES footnote “G” indicates an individual move or the first names do not match.
Intelligent Mail Barcodes
Full Service Intelligent Mail Bar Codes replaced the old Post Net bar codes that were required to receive presorted mail discounts.
The Intelligent Mail Barcode (IMB), is a new Postal Service barcode used to sort and track letters and flats. The Postal Service is promoting use of the Intelligent Mail barcode because it expands the ability to track individual mail pieces and provides customers with greater visibility into the mail stream.
