'''CASS'''The ('''Coding Accuracy Support System''' ('''CASS''') enables the [[United States Postal Service]] (USPS) to evaluate the [[accuracy]] of [[software]] that cleanscorrects and matches addresses[[street address]]es. CASS Certification[[certification]] is offered to all [[Advertising mail|mailers]], [[service bureausbureau]]s, and software vendors[[vendor]]s that would like the [[USPS]] to evaluate the [[Quality (business)|quality]] of their address-matching software and improve the accuracy of their [[ZIP Code|ZIP]]+4, [[carrier route]], and five-digit coding accuracy.

For software vendors and service bureaus, CASS Certification must be renewed annually with the USPS to meet current CASS Certification cycle requirements.

CASS Certified products are listed in USPS literature and on its web site. CASS software will correct and standardize addresses. It will also add missing address information, such as [[ZIP Codes]]codes, cities, and states,[[state (US)|state]]s to ensure the address is complete. Starting with 2007 Cycle L, CASS software will also perform [[Deliverydelivery Pointpoint]] [[Data Validationvalidation|validation]] to verify whether or not an address is a deliverable address and accesscheck against the USPS [[Locatable Address Conversion System]] to update addresses that have been renamed or renumbered. Cycle L also requires that the address be confirmed with the [[Delivery Point Validation]] before adding a +4 Code to the ZIP Code.

An example of what CASS software will correct in an address:

# Unsorted mail

# Mail that is deliverable, but requires extra effort to determine the proper ___location to which it should be delivered.<ref>{{cite web |date=2007-06-26 |title=CASS Certification Requirements, A Mailer's Guide |url=http://ribbs.usps.gov/cassmass/documents/tech_guides/CASS%20Cert%20Req%20MAILERS%20Guide.pdf |url-status=dead |archive-url=https://web.archive.org/web/20190301074628/http://ribbs.usps.gov/cassmass/documents/tech_guides/CASS%20Cert%20Req%20MAILERS%20Guide.pdf |archive-date=2019-03-01 |accessdate=2007-07-27 |publisher=United States Postal Service}}</ref>

Mailers who use CASS software to check the addresses of their mailing may be able to qualify for [[discounts and allowances|discount]]ed postage rates from the USPS.

AnAs an example of what CASS software will correct in an address, an input of:<blockquote>

1 MICROWSOFT<br />

REDMUND WA<br />

</blockquote>

Produces the output of:

<blockquote>

MICROSOFT<br />

1 MICROSOFT WAY<br />

REDMOND WA 98052-8300<br />

</blockquote>

Here the street and city name mispellingsmisspellings have been corrected (MICROWSOFT → MICROSOFT; REDMUND → REDMOND); street suffix (WAY), zipZIP code and zip4ZIP+4 add-on have been added; and, in this case, the address was determined to be the ___location of a business.

In addition to an updated address, CASS software can also return descriptive information about the address. The information falls into two categories:
