If you heard that Dunkin' is handing out over a million free coffees today and assumed it was an April Fools' prank — that's exactly what they expected. And that's exactly why they named the promo code StillNotAJoke.
What's the Deal?
This April Fools' Day, Dunkin' is skipping the pranks and going straight to the good stuff: 1,000,001 free hot or iced coffees, available today only through the Dunkin' app. The offer is open to all Dunkin' Rewards members across the United States, while supplies last.
The tongue-in-cheek promo code — STILLNOTAJOKE — leans into the very skepticism it's trying to overcome. Last year, Dunkin' gave away one million free coffees on April 1 and many customers reportedly thought it was a prank. This year, the brand went one better — literally — with that extra single coffee tacked on "for anyone still not convinced."
How to Claim Your Free Coffee
Getting your free cup is simple:
- Download or open the Dunkin' app on your smartphone.
- Sign up or log in as a Dunkin' Rewards member (membership is free).
- Enter the promo code:
STILLNOTAJOKE - A Free Coffee Certificate will be added to your account.
- Redeem it at your nearest Dunkin' location.
Good news: You don't have to redeem it today. The Free Coffee Certificate is valid for 7 days after you enter the promo code — so you have until April 8, 2026 to use it.
What's Included (and What's Not)
The free coffee offer covers a wide range of options, but not everything on the menu:
| ✅ Included | ❌ Not Included |
|---|---|
| Hot Coffee (any size up to Large) | Extra-Large Hot Coffee |
| Iced Coffee (any size) | Cold Brew |
| Lattes | |
| Refreshers | |
| Teas |
The offer is limited to one free coffee per customer, and can only be redeemed through the app — you won't be able to claim it at the counter without the digital certificate.
Why Is Dunkin' Doing This?
April Fools' Day is a tough one for brands. Any promotion announced on April 1 is immediately met with eye-rolls and skepticism. Rather than fight that instinct, Dunkin' has leaned into it — turning the holiday into an annual tradition of genuine generosity wrapped in a wink.
It's smart marketing, no doubt. Getting millions of customers to open the app, sign up for Rewards, and walk into a store is a win for the brand. But for coffee lovers, the math is simple: free coffee is free coffee.
The Fine Print
- Offer valid April 1, 2026 only (promo code must be entered today).

- Available to Dunkin' Rewards members only via the Dunkin' app.

Bottom Line
Whether you're dodging office pranks or just need something real to hold onto on this most untrustworthy of days, Dunkin' has you covered. Open the app, enter STILLNOTAJOKE, and enjoy your well-deserved cup of coffee.
Because on April 1st, a free coffee might just be the only thing you can trust.
