Port rankings
Seaports ranked by carrier connectivity — worldwide and for the major maritime nations.
Seadex indexes 3760 seaports across 199 countries and territories, together with the shipping lines recorded as serving each of them. These rankings distil that dataset into a single connectivity signal: the more distinct carriers call at a port, the better connected it is to global trade lanes.
Shanghai Port currently tops the worldwide ranking with 43 shipping lines. Rankings are recomputed daily; pick a country below or browse the global top 100.
