Dunkin' Offers Free Coffee on April 1, 2025

As a twist on the typical April Fools' Day jokes, Dunkin' today is giving away up to one million free hot or iced coffees or cold brews of any size to Dunkin' Rewards members, while supplies last.

To take advantage of the freebie, just enter the code "ThisIsNotAJoke" in the Dunkin' app today, Tuesday, April 1, 2025. Once entered, you have until Tuesday, April 8, 2025, to redeem your free drink by scanning your app in store or placing a mobile order.

The deal applies to drip coffee and cold brew only. Espresso and espresso-based drinks and Nitro Cold Brew are not included in the promotion.
