In which city is WhatsApp's headquarters located?

WhatsApp’s headquarters was located in Mountain View, California. The company was founded and operated there as WhatsApp Inc. before Facebook acquired it in 2014.

Mountain View is part of Silicon Valley, the technology region surrounding the southern end of San Francisco Bay. WhatsApp’s early office reflected the company’s unusually small, focused startup culture: founders Jan Koum and Brian Acton built a globally used messaging service with a relatively modest team compared with major internet companies.

The city is sometimes confused with nearby Palo Alto, San Francisco, or Cupertino because all are strongly associated with major technology businesses. Palo Alto is known for companies such as Hewlett-Packard and parts of the early Silicon Valley startup scene; Cupertino is Apple’s home city; San Francisco is a larger urban center north of the Bay. WhatsApp’s own corporate base, however, was in Mountain View. After Facebook’s acquisition, WhatsApp retained its brand and operated with independence for a period, even as it became part of Facebook, now Meta.
