Global Membership

Starting in 2015, Sister Cities International dramatically restructured its Global Membership structure and services. Global Membership is available to all non-U.S. cities that wish to enjoy the benefits of the Sister Cities International network. Membership is now divided into classes according to population size, mirroring the structure of U.S. membership. Global Membership is open to all non-U.S. cities, districts, counties, provinces, or other communities. Cities can only be registered by government employees, elected officials, or organizations formally recognized by local government as the representative of their sister city program. If you have questions about whether you’re eligible, please contact us at
