Dunkin code: Here's how to get the free coffee today, September 24, using the promo code before it runs out

Dunkin' fans have a reason to check their apps today. The coffee chain is giving away one million free coffees on Thursday, Sept. 24. The offer starts at noon ET, and there is a promo code to enter through the Dunkin' mobile app. But there is a catch. The deal is only available to the first one million customers who redeem it, as per a report by USA Today.

The code is “JUST4U.” So, if you want the free coffee, it may be worth opening the app as soon as the offer goes live.

Dunkin free coffee promo code and how to use it

Dunkin' confirmed to USA Today that one million free coffees will be available starting at 12 p.m. ET on Thursday.

Customers can get the deal by entering the promo code “JUST4U” in the Dunkin' mobile app. To find the code section, open the app and go to the “offers” page. Scroll down until you see the box that says “enter a promo code.” Type in “JUST4U” and follow the steps to redeem the offer.



The giveaway is limited to the first one million customers who enter the code. That means the offer could go quickly once the promotion begins. Dunkin' is also planning another coffee offer for Rewards members that day.

More free Dunkin' coffee is coming Sept. 29

Dunkin' Rewards members will be able to get a free medium hot or iced coffee with any purchase through the Dunkin' app on National Coffee Day.

There are a few limits to that offer. Cold brew and hot espresso beverages are excluded. The offer also cannot be combined with another promotion.

National Coffee Day will also bring a new Dunkin' collaboration with L.L. Bean. The two brands are launching a sweater and boat and tote on Tuesday, Sept. 29 at 10 a.m. ET. The items will be available online through L.L. Bean.

Dunkin' has already offered a look at the collaboration. A sweater cup sleeve was available on Tuesday, Sept. 22, while supplies lasted.



The coffee chain is also selling a limited-edition L.L. Bean coffee tote accessory. That item will be available starting Sept. 29 at 10 a.m. ET on DunkinRunsonMerch.com.

For now, the main deal for Dunkin' customers is the Sept. 24 giveaway. With one million free coffees available, customers who want to use the “JUST4U” promo code will need to act quickly.

The offer gives Dunkin' Rewards members a chance to grab a free coffee today, while another free coffee deal is already planned for National Coffee Day next week.
