WhatsApp has now passed two billion monthly active users. Since launching its beta test phase, the standalone instant messaging app has seen an enormous growth in India, the country where it’s based. The company says about 450 million of the users today are in India alone.

Earlier this year, WhatsApp bumped up its payment service to 65 countries, and added ‘hostile’ voice calling capabilities. The company also introduced ‘WhatsApp Business’, a standalone messaging app for customers of companies such as Uber and Blue Apron.

The expansion in international markets came after the company’s merger with Facebook. The deal is said to be worth about $22 billion, and included sending a token 0.1 percent of the acquisition value to WhatsApp users on a global basis.

The new milestone is an interesting piece of data, and the company hasn’t shared how it plans to reach the 3 billion users mark any time soon. That could mean it will have to raise money, expand its user base to more countries and increase its customer base – things that require a large chunk of money.
