.BB is the Internet country code top-level domain (ccTLD) for Barbados. In 1991, the University of Puerto Rico received the delegation for the Barbados top-level domain. In 1996 the delegation was moved from the University to the incumbent local exchange carrier, Cable & Wireless (BARTEL) Ltd.

In 2001 both Cable and Wireless and the government of Barbados signed a memorandum of understanding. This agreement allowed Cable and wireless to continue administration of the Barbados ccTLD until the government could find a suitable alternative.
