Facebook announced it is building a Yellow Pages feature into WhatsApp, allowing users to look up local business information.

Once a staple of everyday life, the Yellow Pages directory have fallen out of favor, replaced by digital alternatives. In Facebook’s quest to monetize WhatsApp, and make it a critical business tool, the company is looking to provide a digital Yellow Pages feature that will help users find local business information.

CEO Mark Zuckerberg announced the feature in a Facebook post:

We’re building a modern-day Yellow Pages into WhatsApp where you can look up and contact local businesses right inside the app. Launching in São Paulo today, and hopefully more places soon.
