PostGrid Glossary LACSLink®

LACSLink®

LACSLink® (Locatable Address Conversion System) is a USPS database that provides updated address information for locations that have undergone changes such as renaming or renumbering. This service is essential for maintaining accurate address records, especially in areas where local governments have implemented 911 emergency systems that require updated street names and house numbers. By using LACSLink®, businesses can ensure that their mail reaches the correct address, thereby reducing the risk of undelivered or returned mail.
