{{short description|System for correcting US postal addresses}}

The '''Coding Accuracy Support System''' ('''CASS''') enables the [[United States Postal Service]] (USPS) to evaluate the [[accuracy]] of [[software]] that corrects and matches [[street address]]es. CASS [[certification]] is offered to all [[Advertising mail|mailers]], [[service bureau]]s, and software [[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.

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, cities, and [[state (US)|state]]s, to ensure the address is complete. Starting with 2007 Cycle L, CASS software will also perform [[delivery point]] [[Data validation|validation]] to verify whether or not an address is a deliverable address and check against the USPS [[Locatable Address Conversion System]] to update addresses that have been renamed or renumbered.

A correct address saves the Postal Service time, money and manpower by reducing the volume of:

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>

The input of:

<blockquote>

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 misspellings have been corrected (MICROWSOFT → MICROSOFT; REDMUND → REDMOND); street suffix (WAY), ZIP code and ZIP+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:
