The cost of a one-year listing in the DIA CSO Directory is $1250. Your company listing, consisting of your company name and contact information, narrative company description, and services you offer, will be displayed in DIA's online CSO directory for one full year. Our new automated directory system allows you to easily update this listing to reflect changes in your company's location, personnel, or services, throughout the year.

Once each year, DIA will download and print all online listings and publish a hardcopy directory. Your listing will appear in this hardcopy directory as it appears in the online directory on the date of this download, so it is important to keep your listing accurate and up to date.

Your CSO Directory listing purchase also includes a unique company login (customer number) and password that will allow you to access and modify your listing throughout the year. It can also be used to renew your listing for subsequent years. It is important that you carefully protect this information.
