Where is Facebook headquarters?

Q. What is the address of Facebook’s main office?

Adam answers:

The address of HQ is:

1601 Willow Road
Menlo Park, CA, 94025

Facebook officially uses the address “1 Hacker Way, Menlo Park, CA 94025” for its headquarters, but the Willow Road address is more helpful if you are actually trying to make your way to the site.
