If you've seen posts saying Dunkin' is giving away free coffee today, you're not alone. Fans across the US are watching the Dunkin' app for a promo code. Here's what is officially confirmed, what has only been reported so far, and how to make sure you don't miss out.
Quick answer
- Officially confirmed: Dunkin' Rewards members get a free medium hot or iced coffee with any purchase in the Dunkin' app on Tuesday, September 29 (National Coffee Day).
- Widely reported, not yet in Dunkin's official newsroom: A giveaway of 1 million free coffees through a promo code on Thursday, September 24.
Is there a Dunkin' free coffee code today?
Several outlets are reporting one. According to a report on Yahoo Lifestyle, Dunkin' is giving away 1 million free hot or iced coffees on September 24, with a promo code expected around noon ET. The report says Rewards members will need to enter the code in the Dunkin' app, and that the free coffee can then be redeemed through Sunday, September 27.
However, Dunkin' has not announced this giveaway in its official newsroom, and NorthJersey.com noted on Thursday morning that the code had not dropped yet. Until the code appears on Dunkin's own app or social accounts, treat any code shared elsewhere with caution.
The reports are believable because Dunkin' has done this before. In February 2026, Dunkin' offered Rewards members a free coffee of any size with the promo code GOODWILLDUNKIN, a post that still appears on its official newsroom.
How to be ready if the code drops
- Download the Dunkin' app and sign in or create a free account now, not when the code drops.
- Join Dunkin' Rewards. These codes are usually for members only.
- Watch Dunkin's official app and social accounts around noon ET, and only use a code that comes from Dunkin' itself.

The Dunkin' x L.L.Bean fall collaboration

- September 22: A limited-edition Birdseye Sweater Cup Sleeve with any hot or iced coffee, while supplies last.
- September 27: A pop-up at the L.L.Bean Seaport store in Boston (56 Seaport Blvd.) from 10 a.m. to 1 p.m., with complimentary coffee and Refreshers while supplies last.

From September 21 to 29, L.L.Bean's Bootmobile is touring select Dunkin' locations from Maine to Boston, with a chance to receive Dunkin' gift cards.
Not a Rewards member? Here's what you get
Joining is free. Per Dunkin's official Rewards page, members earn 10 points per $1 spent on qualifying purchases, and rewards start at 150 points, which works out to $15 spent. Visiting 12 times in a calendar month unlocks Boosted Status, which raises your earning rate to 12 points per $1 for three months.
Bottom line
The September 29 free coffee is confirmed, so mark your calendar. For today's reported code, get your app and Rewards account ready, watch Dunkin's official channels around noon ET, and skip any "code" that isn't coming from Dunkin' itself.
This article will be updated once Dunkin' officially posts the promo code. Offers are valid at participating US locations only.
