About .cu
Cuba's country code top-level domain, .cu, represents the Caribbean island nation in the global domain name system. Administered by the University of Informatics Sciences (UCI) under the oversight of the Cuban state, .cu is heavily regulated and predominantly used by government entities, state-run enterprises, and approved academic institutions. Cuba's internet access has historically been restricted, which has limited the breadth of the .cu namespace compared to other ccTLDs.
The .cu TLD was delegated in 1992 and operates under strict government control consistent with Cuba's broader communications policies. Foreign registrations and private sector use are highly limited. As Cuba has gradually expanded internet access in recent years, the .cu domain space has begun to grow, though it remains one of the more tightly managed ccTLDs in the world. Second-level domains such as .co.cu and .com.cu are used for commercial entities.
