Like mtmail said, it's not a secret; just a feature we haven't built yet.
Depending on your use-case, there are a couple of current options you might look at:
https://ycombinator.joinmonday.com/ is a list of all YC companies that are hiring and their current location. That data is generated by scraping the companies' websites.
https://www.workatastartup.com/directory is our internal directory of all YC companies that are hiring for technical roles, and also has location. This data is supplied by the companies directly.

May I ask what you were planning to use it for?
