Most of the records in the LACSLink system are for changing rural-style box numbers to street names. For example,
RR 1 BOX 127A is converted to 17255 SCENIC RD
Some LACSLink records handle renumbered Post Office™ boxes. For example,
PO BOX 123 is converted to PO BOX 555123
Some LACSLink records handle changes when streets are renamed and the house or apartment number also changes. For example,
905 LOWER AVE is converted to 1125 FREEDOM DR
The LACSLink database occupies approximately 370 megabytes. A CD-ROM containing LACSLink is released every month, for use with the corresponding ZP4 edition. Once LACSLink data is installed, ZP4 automatically performs LACSLink conversions like those shown above. The conversion of rural box addresses to street addresses by local governments is ongoing. The LACS flag indicates if any ZIP + 4® database record includes addresses that can be converted using LACSLink.
LACSLink lookups may not be performed after the two-month expiration date of the LACSLink database. The product's license prohibits using LACSLink for the manufacture of address lists, and also prohibits the LACSLink database being exported outside the United States. A "violation" will occur if ZP4 detects LACSLink is being used to generate address lists, and subsequent LACSLink output will be suppressed until a restart code is obtained from Semaphore Corporation to clear the violation. Violation monitoring and enforcement is a requirement of the Postal Service. Semaphore Corporation is required to notify the Postal Service of your name and address when you request a LACSLink restart code. If you repeatedly generate LACSLink violations, the Postal Service will prohibit you from continuing to use the LACSLink system.
LACSLink, SuiteLink and DPV® are required to determine the proper CASS ZIP + 4 code for an address.

A CD-ROM containing SuiteLink is released every month, for use with a corresponding ZP4 edition. Once SuiteLink data is installed, ZP4 is able to automatically determine the secondary (suite) information for a company address, if the company is listed in the SuiteLink database. As of May 2011, 21 million records are included in the SuiteLink product.
The disc containing SuiteLink is typically purchased at the same time as a ZP4 disc. ZP4 can be purchased without SuiteLink, but purchasing SuiteLink requires purchasing the corresponding ZP4 disc (SuiteLink lookups require ZP4).
SuiteLink lookups may not be performed after the expiration date of the SuiteLink database. Once a SuiteLink database expires, you must purchase a current SuiteLink database, and the corresponding ZP4 edition, to continue performing SuiteLink lookups. LACSLink, SuiteLink and DPV® are required to determine the proper CASS ZIP + 4 code for an address.
