The LACSLink Product is a secure dataset of converted addresses that primarily arise from the implementation of the 911 system, which commonly involves changing rural-style addresses to city-style addresses. The LACSLink Product also contains existing city-style addresses that have been renamed or renumbered.

The LACSLink Product:

  • Reduces undeliverable mail by providing the most current address information for matches made to the LACSLink file.
  • Lowers mailer costs by reducing the number of undeliverable and duplicate mailpieces by using the most current address information.
  • Provides the opportunity for faster product/service marketing through accurate mail delivery.

Effective August 1, 2007, CASS Certified™ software requires use of both the LACSLink and DPV® products when processing address lists. This requirement ensures ZIP + 4® codes will be assigned only when the primary number of the address can be validated using the DPV Product and whether the input address reflects any applicable municipality address conversions.
