The service has also hit two billion checkins.

Today is Foursquare day! Cuz it’s 4/16, and 4 squared = 16. Get it? Well whatever, location check-in startup Foursquare celebrates today as a holiday, with t-shirts and everything. This year, they decided to announce a major company milestone in accordance with the holiday: over the past four months, the company has gained five million users, bringing their total number of users to over 20 million. They’ve also reached two billion check-ins, which is no small feat in itself.

In true Foursquare fashion, the milestone was announced via a badge: Anyone who checks in at any location today will get a Foursquare Day 2012 badge that announces the user totals. The badge reads:

In 2010, foursquare fans declared April 16 4sqDay (4/4^2 – nerds after our own heart!). Two years and two billion check-ins later, you’re still why we get out of bed each day. Thanks to all 20 million of you for making us part of your lives. Happy 4sqDay!

According to The Next Web, Foursquare “was flirting with 15 million users in December and is likely to have blasted past the 20 million user prior to today but this is the first reference to the milestone that we have seen.”

When the team hit 15 million users in December, Mashable reported that 50 percent of users are US-based while the other 50 percent are international. We emailed Foursquare to ask for an updated figure on how many of their users are domestic versus international, but didn’t immediately hear back.

Unfortunately, it appears that Foursquare CEO Dennis Crowley isn’t in New York to celebrate the milestone. Yesterday, he tweeted a view of the ocean from the Virgin Islands with the hashtag #CrowleyFamilyVacation. Yes, he checked in to the St. Thomas airport.
