Fans of Dunkin’ Donuts can get a free cup of coffee, but you’ll have to act fast. On April 1, the coffee and doughnut chain is giving away up to a million hot or iced coffees and cold brews of any size for April Fools’ Day, according to a news release. Espresso drinks are excluded.

Dunkin’ giving out free coffee on April 1 isn’t an April Fools’ Day joke. "While everyone else is busy pulling pranks this April Fools’ Day, Dunkin’ is skipping the tricks and serving up something real: a free coffee to fuel New Englanders on the one day you might need it the most‚" Dunkin’ said in a statement.

Yes! Dunkin' rewards members can get a free hot or iced coffee or cold brew of any size on the Dunkin' app by entering the code ThisIsNotAJoke. The free coffee may be redeemed only on the Dunkin' rewards app. Dunkin' is giving out a million free coffees, while supplies last, and customers may redeem the code only once.
