About .rio

.rio is a generic top-level domain (gTLD) for the city of Rio de Janeiro, Brazil. It is operated by Empresa Municipal de Informática SA, known as IPLANRIO, the city's official IT company. There are no strict eligibility rules for who can register a .rio domain, but the registry's site at nic.rio suggests it is aimed at businesses, organizations, and individuals with a connection to Rio de Janeiro or the city's global brand. The domain was delegated in May 2014, giving Rio its own slice of the internet tied to its name and culture.

History

Rio de Janeiro was one of the first cities to get a dedicated gTLD under ICANN's new program. The delegation in 2014 was a big step for the city's digital identity. IPLANRIO and NIC.br handle the technical backend.
