Popular mobile check-in application Foursquare today announced that it grew 3400% in 2010. The company now stands at 6 million users.

Other interesting stats include more than 381 million total check-ins accounting for every country (including North Korea) as well as a check-in from space. California also appears to have the most fit Foursquare users, being the top state for gym check-ins.

Foursquare has shown no signs of slowing down. Reports surfacing today claim that the company is looking for its next round of funding at a valuation of $250 million, which would equate to around $40 million in funds if you consider its last $21 million round was at a valuation of $120 million.

Foursquare, based in New York City and founded in 2009 currently has more than 40 employees in its hometown and a new engineering office it’s opening in San Francisco.
