 The
411 on CASS™
The US Postal Service’s Coding Accuracy Support
System evaluates the accuracy of data-cleansing
software. CASS-certification is available to all
mailers, service bureaus, and software vendors. What
exactly is CASS?
On August 1, the USPS® began Cycle L of
certification. It requires the use of DPV™ and
LACSLink™ technologies when processing address
lists. Each cycle, or round of certification
requirements, lasts a year. Each year, the new cycle
raises the bar for quality within the CASS
certification process by implementing new
technologies and requirements in the address
matching software industry.
DPV validates each address for one of the following
scenarios against the more than 145 million delivery
points (deliverable addresses) on file with the USPS.
It determines that either the address has the
correct primary and secondary data, the address has
the correct primary but not secondary data, or the
address cannot be validated. It does not correct any
missing data.
LACSLink automates the retrieval of new addresses
that have been converted by local municipalities,
usually when the community has implemented a 911
emergency system. 911 address conversions normally
involve changing rural-style addresses to city-style
addresses, but in some instances municipal
conversions may result in the renaming or
renumbering of existing city-style addresses.
