LACSLink® and SuiteLink® Updates
Overview
LACSLink® (Locatable Address Conversion System) and SuiteLink® are USPS® data enhancement tools designed to improve address accuracy and ensure deliverability for both residential and business mail.
-
LACSLink® converts outdated or rural route addresses into city-style formats — critical for emergency response and consistent delivery.
-
SuiteLink® adds missing suite or secondary information to business addresses, ensuring mail reaches the correct department or office.
Together, these two services enhance data precision, improve routing efficiency, and ensure full compliance with USPS® addressing standards.
How LACSLink® and SuiteLink® Work
LACSLink® Process
LACSLink® maintains a USPS® database of address conversions resulting from rural-to-city style renumbering or street renaming initiatives.
When an address is processed, EZ24x7 checks it against the LACSLink® file and returns:
-
The new, converted address with the updated street name and number.
-
The original address and conversion status code.
-
Additional postal details such as ZIP+4®, carrier route, and delivery point code.
This process guarantees that mail sent to renamed or restructured locations is properly delivered without delay.
SuiteLink® Process
SuiteLink® focuses on business addresses. When a company’s suite or secondary information is missing, SuiteLink® enhances the record by appending accurate suite identifiers based on USPS®-verified data.
This ensures that mail reaches the correct office, floor, or department within multi-tenant business locations.
