The Smithsonian uses outside vendors to provide certain services, such as companies that process credit card transactions for the Smithsonian. These third-party vendors will have access to the information needed to perform their functions, but may not use your information for any other purpose. Some Smithsonian units, on occasion, rent or exchange select member name and address information with other charitable or cultural non-profit organizations. You will be notified of any such sharing and provided an opportunity to opt-out.
