Rakuten Viber, or simply Viber, is a cross-platform voice over IP (VoIP) and instant messaging (IM) software application owned by Japanese multinational company Rakuten, provided as freeware for the Android, iOS, Microsoft Windows, macOS and Linux platforms.[1] Users are registered and identified through a cellular telephone number, although the service is accessible on desktop platforms without needing mobile connectivity.[1] In addition to instant messaging it allows users to exchange media such as images and video records, and also provides a paid international landline and mobile calling service called Rakuten Viber Out.[2] As of 2018, there are over a billion registered users on the network.[3][4]
The software was started in 2010 by a company that was apparently Cyprus-based in 2024[5] Viber Media, which was bought by Rakuten in 2014. Since 2017, its corporate name has been Rakuten Viber. It is based in Cyprus[6] [failed verification] with offices in London, Manila, Moscow, Paris, San Francisco, Singapore, Tokyo, and Beijing.[7][8]
