The 911 Emergency Response System initiated the conversion of older rural addresses to modern, urban-styled addressing in the 1980's. The purpose was to generate a faster response by accurately associating a physical address with the telephone number making the emergency call to the authorities. The USPS recognized that mailers would improve their deliverability by obtaining this new address data and so created the Locatable Address Conversion System (LACS).
Rural, PO Box, Highway and other non-unique address types are compared to the USPS master conversion file. Addresses in your file that have undergone a permanent conversion are updated.
After running this service, you will receive a result file containing your original input file with the new, corrected data appended to it. Fields are added to your record to store updated addresses. A summary report provides you with statistical data describing your results and a record layout defines field positioning and content.
