WhatsApp (also called WhatsApp Messenger) is an internationally available freeware, cross-platform, centralized instant messaging (IM) and voice-over-IP (VoIP) service owned by American company Meta Platforms.[11] It allows users to send text and voice messages,[12] make voice and video calls, and share images, documents, user locations, and other content.[13][14] WhatsApp's client application runs on mobile devices, and can be accessed from computers.[15] The service requires a cellular mobile telephone number to sign up.[16] In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.[17][18]

The client application was created by WhatsApp Inc. of Mountain View, California, which was acquired by Facebook in February 2014 for approximately US$19.3 billion.[19][20] It became the world's most popular messaging application by 2015,[21][22] and had more than 2 billion users worldwide by February 2020.[23] By 2016, it had become the primary means of Internet communication in regions including Latin America, the Indian subcontinent, and large parts of Europe and Africa.[21]
