How many active users does WhatsApp have?

WhatsApp had over 2 billion monthly active users worldwide. However, for the most accurate and up-to-date information on WhatsApp's user base, I recommend checking the latest reports or announcements from reliable sources such as WhatsApp's official website, parent company Facebook (Meta Platforms, Inc.), or reputable tech news outlets. The number of active users may vary over time due to factors such as user growth, changes in market trends, and regional dynamics.
