Visit our City Search tool search for your community and find the primary contact information for your sister city organization. If you don’t find your city, it means they are not currently a member of the Sister Cities International network. To see if your city has a sister city relationship, do some basic research online or contact the town clerk, mayor’s office, or office of international affairs to see if they can put you in contact with your sister city organization. Most sister city committees have regular meetings that are open to the public.
