dunkin donuts free coffee
Dunkin' frequently runs free coffee promotions for Dunkin' Rewards members. To take advantage of these offers, here is what you need to know as of late September 2026:
Current & Upcoming Promotions
- September 24, 2026: Dunkin' released a limited-time offer for 1 million free hot or iced coffees. The promo code for this giveaway was JUST4U. If you claimed this offer, it is typically redeemable through September 27, 2026.
- National Coffee Day (September 29, 2026): Dunkin' Rewards members can receive a free medium hot or iced coffee with any purchase made through the Dunkin' app. No promo code is typically required for this; the offer is applied in the app.
How to Get Free Coffee at Dunkin'
- Join Dunkin' Rewards: Most of these giveaways are exclusive to loyalty members. You can sign up for free through the Dunkin' app or on their website.
- Monitor the App: Check the "Offers & Rewards" section in the Dunkin' app frequently. This is where you enter promo codes for surprise giveaways.
- Follow Social Media: Dunkin' often announces their "1 million free drinks" flash giveaways on their official social media channels (such as Instagram). These codes are usually released around midday (e.g., 12 p.m. ET) and are claimed very quickly.
- Earn Points: Even when there isn't a specific giveaway, you earn points on every purchase. Once you accrue enough points (e.g., 200 points), you can redeem them for a free beverage reward.
