Reciprocating Zoos

FONZ Memberships are transitioning to Smithsonian’s National Zoo Memberships!

You may have heard that FONZ will be leaving the Zoo — but the Zoo will be starting a new membership program, which will automatically include all current FONZ members. Until the Smithsonian's National Zoo Membership is up and running, you can continue to join or renew, knowing that your membership will smoothly transition to the new program.

Questions about your current membership? Check the Membership FAQs page. If you're not already a member, please consider joining today.

One of the great benefits of being a FONZ member is free or discounted admission to other reciprocating zoos and aquariums, and in some cases, discounts in their shops. When visiting these institutions, please present your current FONZ membership card and an ID. If you have any questions, please contact the Membership Office or call 202-633-2922.

Full List of Reciprocating Zoos

Please note that participating institutions located in close geographic proximity to each other are not required to offer free or discounted admission to each other’s members in order to participate in AZA’s Reciprocal Admissions Program; for this reason, the Smithsonian's National Zoo/FONZ does not reciprocate with The Maryland Zoo.  

This list is updated throughout the year by the Association of Zoos and Aquariums (AZA). Participating organizations may be added or removed, and reserve the right to offer different admission discounts depending on the season or special activities taking place, so it is always a good idea to call ahead.
