A SuiteLink CD-ROM 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 March 2008, 3.7 million businesses are included in the SuiteLink Product.

A SuiteLink disc is typically purchased at the same time as a ZP4 disc. ZP4 can be purchased without a SuiteLink disc, but purchasing a SuiteLink disc requires purchasing the corresponding ZP4 disc (SuiteLink lookups require ZP4).

SuiteLink lookups may not be performed after the 30-day 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.
