YOUR QUESTION. A USEFUL NEXT STEP.
Give an existing connection a useful purpose.
Imagine your community discovers a long-standing partner abroad. A listed relationship is an invitation to learn its story. Ask who began it, what people have done together, and who would welcome a new conversation today.
Search the directory below and open the linked Sister Cities International source. The source label helps you understand the listing. A current local contact helps you understand its activity. Ask schools, businesses, cultural groups, and civic hosts how they have taken part.
Then choose a shared need using the four business questions. A student exchange, a buyer introduction, or a research project may each have a different owner and timeline. Keep that activity record separate from a new opportunity lead.
Try this: Find one listed pair. Ask a local contact for a recent activity, a current partner, and one possible next step.
YOUR QUESTION. YOUR WORKING NOTES.

Sister City and Friendship City are the labels supplied for each listed partner. Emeritus Status means the source marks a relationship as paused or dormant.
This review combines SCI’s U.S.-state and Global Members views, including pairs between places outside the United States. Other partnerships may exist beyond these directory listings. A listing does not establish present activity, paid membership, or economic results.
These existing relationships have their own source records. The Opportunity Index helps you explore possible new connections.

The source supplies this relationship label. It does not establish recent visits, active projects, membership dues, or business results.
The source contains 1,727 relationship rows: 1,583 Sister City, 82 Friendship City, and 62 Emeritus Status. Repeated and exact reciprocal listings are linked for display. Every observation is kept; this page shows 1,708 distinct source pairs.
The Global Members view adds 67 source rows. After checking overlap, it adds 49 displayed pairs: 39 between non-U.S. places and 10 more involving a U.S. place. The country listing re-presents the original 1,660 U.S.-state rows in reverse and is retained as reconciliation evidence.
Pair matching uses exact source names and complete reciprocal pairs. Different spellings and uncertain place identities remain separate until reviewed.
Source names and labels are preserved. Place identities, geographic codes, local government confirmation, and recent activity still need review. A listed partner can be a district, county, or region as well as a city.
