How Does LACSLink Work? - Code-1_Plus - 5.0

The following steps describe the sequence of CODE-1 Plus LACS^Link processing:

1. Standardizes input address information to conform with USPS requirements including the ZIP + 4 Code,

2. Matches the address against the LACS file.

3. If an exact match is made with the old address information on the LACS file, processing updates the address.

4. If a match is found, CODE-1 Plus returns the following information:

   • Original input address from the mailer

   • Input address as standardized and appended with the ZIP + 4 Code (if possible)

   • Standardized new address when the standardized input address matches the old address on the LACS file

   • National Delivery Index (NDI) report that includes a breakdown of deliverable address information

5. If no match is found, CODE-1 Plus returns the following information:

   • Original input address

   • Standardized ZIP + 4 coded version of the input address

   • USPS Form 3553

   • NDI report
