Get A Free Coffee From Dunkin’ Today

Getting a free coffee is pretty simple. Customers need to open the Dunkin’ app and enter the promo code SIZEDOESNTMATTER in the offer section. The promo code is only valid on October 21, 2026, and each customer can claim one free coffee. Once the code has been entered successfully, the free coffee certificate remains valid for five days.

Once the code has been accepted, the free coffee certificate can be used to claim a qualifying drink at a participating Dunkin’ location.

The promotion covers hot or iced coffee, so customers can choose whichever suits their mood. You can go for any size, except for hot extra large because that would be asking for too much. 

Spidey D Is Behind Dunkin’s Latest Free Coffee Giveaway

Spidey D, Dunkin’s spider character made from a chocolate-glazed Munchkins donut hole and a purple-frosted donut, has taken over the brand’s social media for a Halloween-themed campaign. The character announced the giveaway through Dunkin’s official channels, with the promo code serving for a free coffee. 

The code itself, SIZEDOESNTMATTER, is a playful nod to the offer’s range of coffee sizes. After all, getting a free coffee is already a win, and having some flexibility over the size makes the deal even more appealing.

And the best part is there’s no need to purchase a qualifying drink or try a new menu item to enjoy the promotion.

Dunkin’ Keeps Giving

Anyone who follows Dunkin’s promotions won’t be surprised by this new giveaway. The chain has handed out free coffee on several occasions in 2026, using limited-time promo codes to get customers into the app.

Back in April, Dunkin’ 1,000,001 free coffees as part of its April Fools’ campaign. And on May 19th, the chain offered another one million free coffees. 

In August, Dunkin’ switched things up by giving away one million free espresso beverages to celebrate pumpkin season. 

And in between all these, Dunkin’ gave away free refreshers, so, there’s basically no month that goes by without Dunkin’ doing something for its fans.

Don’t Wait Too Long

The October 21st giveaway has one million codes available, and customers can enter the code only on the day of the promotion. The good news is that a successfully claimed certificate remains valid for five days, giving customers some breathing room to pick up their drink. Just make sure to claim the offer before the codes run out.
