WhatsApp (officially WhatsApp Messenger) is an instant messaging (IM) and voice-over-IP (VoIP) service owned by technology conglomerate Meta.[14] It allows users to send text, voice messages and video messages,[15] make voice and video calls, and share images, documents, user locations, and other content.[16][17] WhatsApp's client application runs on mobile devices, and can be accessed from computers.[18] The service requires a cellular mobile telephone number to sign up.[19] In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.[20][21]

The service was created by WhatsApp Inc. of Mountain View, California, which was acquired by Facebook in February 2014 for approximately US$19.3 billion.[22][23] It became the world's most popular messaging application by 2015,[24][25] and had more than 2 billion users worldwide by February 2020.[26] 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.[24]
