The company publishes the redemption rules for its survey and never names the survey address. Its FAQ states the coupon expires 14 days from issue, covers one free classic donut with a medium or larger beverage, excludes cooler beverages, is not valid on Mobile App orders and is limited to one per customer per visit. Any guide putting the coupon at 30 days is contradicted by the company; the ones naming telldunkin.com are not confirmed by it.
What you need
12 itemsHow to take the survey
Take the address off the receipt, not off a search result
Guides split between telldunkin.com and dunkinrunsonyou.com, and several assert one replaced the other. Dunkin's own FAQ names neither. Both resolve, so neither is obviously wrong — which is why the printed line on your paper is the one to type.
Treat the window as three days
One guide says 3 to 5 days from the visit; two say within three. Dunkin' publishes no survey window at all, only a coupon expiry. With nothing first-party to appeal to, the shortest claim is the safe one.
Do not count digits against a published figure
A single guide puts the code at 18 digits and the rest give no length. Enter what is printed. A mismatch with somebody's number is not evidence your code is wrong, and editing it to fit is how a good code is rejected.
Note the coupon's 14 days, because that part is settled
Dunkin's FAQ states the coupon or offer code expires 14 days from date of issue. A widely repeated guide says 30. Where the company and a guide disagree, the company's number is the one a franchisee honours at the counter.
Buy the right drink, in the right way
The free classic donut requires a medium or larger Dunkin' beverage, and cooler beverages are excluded. The offer is not valid on Mobile App orders, and the limit is one coupon per customer per visit. All four come from Dunkin'.
If something goes wrong
My coupon was refused as expired
- Cause
- More than 14 days since it was issued
- Fix
- That is Dunkin's published figure, not a store decision. A guide quoting 30 days is contradicted by the company's FAQ.
The offer would not apply in the app
- Cause
- It is not valid on Mobile App orders
- Fix
- Order in store. This is stated in the redemption rules and is not something a franchisee can override.
My drink did not qualify
- Cause
- It was a cooler beverage, or smaller than a medium
- Fix
- The condition is a medium or larger Dunkin' beverage, with cooler beverages excluded. Both halves matter.
I have two coupons and only used one
- Cause
- The limit is one coupon per customer per visit
- Fix
- Split them across visits. Nothing prevents the second being used later, inside its own 14 days.
Two sites claim to be the survey
- Cause
- Guides disagree over telldunkin.com and dunkinrunsonyou.com
- Fix
- Type the address on your receipt. Dunkin' does not name either domain, so no guide settles it for you.
My receipt has no survey invitation
- Cause
- Participation is a franchisee decision
- Fix
- No workaround. The Make It Right Guarantee still covers an order that went wrong, but it pays no coupon.
What’s fixed, and what actually varies
Dunkin' is the reverse of most surveys here. The reward rules are documented by the company; the entry route is documented only by other people.
Fixed
- The coupon or offer code expires 14 days from date of issue
- The reward is one free classic donut with a medium or larger beverage
- Cooler beverages are excluded from the qualifying purchase
- The offer is not valid on Mobile App orders
- The limit is one coupon per customer per visit
- Dunkin' calls it the Guest Satisfaction Survey
Varies
- The survey address. Guides name telldunkin.com and dunkinrunsonyou.com; Dunkin' names neither
- The window to take it — 3 days in two guides, 3 to 5 in another, none from Dunkin'
- The code length, given as 18 digits by one guide and left blank by the rest
- Coupon life in the guides: 14 days in two, 30 days in a third
- Whether your franchisee prints an invitation at all
- Which drinks a particular store treats as cooler beverages
Two things settle this quickly. The receipt names the address and the deadline for taking the survey; the Dunkin' FAQ settles everything about redeeming the coupon. If a page gives the coupon 30 days, it is describing something the company contradicts in writing.
How Dunkin' compares
Dunkin' documents the redemption end better than either of these, and the entry end worse.
| Chain | What you enter | Window | Typical reward |
|---|---|---|---|
| Dunkin' | Code from the receipt; address unnamed by Dunkin' | 3 to 5 days per guides, none published | Free classic donut with a medium or larger drink |
| Burger King | Survey code from the receipt | 48 hours on the receipt | Whopper or chicken sandwich |
| Chick-fil-A | Serial number or Survey ID code, no fallback | None published | Free sandwich, emailed as a QR code |
Participation is set by each franchisee. Your own receipt overrides this table.
Burger King's help centre and Dunkin's FAQ do the same job from opposite ends: both publish the code's life and the redemption limits, and neither publishes the deadline printed on the receipt. Chick-fil-A publishes a 2-day clock.
The company documents the coupon and not the survey
Almost every published guide leads with an address and a window: telldunkin.com, or dunkinrunsonyou.com, and three to five days from the visit. Several assert that one domain replaced the other. Checked on 19 August 2026, both resolve, and Dunkin's own FAQ names neither.
What that FAQ does carry is a set of redemption rules under a heading calling the programme the Guest Satisfaction Survey. Four conditions are stated plainly: the coupon or offer code expires 14 days from date of issue; it covers one free classic donut with the purchase of a medium or larger Dunkin' beverage, excluding cooler beverages; it is not valid on Mobile App orders; and the limit is one coupon per customer per visit.
Three of those four appear in no guide reviewed here. The cooler-beverage exclusion does not appear at all, and nor does the Mobile App restriction — both are conditions people discover at the register.
The fourth settles an argument. One guide gives the coupon 30 days; two give it 14. The company says 14 days from date of issue.
The shape is the opposite of most brands: precise about what the reward is worth, silent about how to earn it, which leaves the entry route to whoever ranks. Dunkin' sits under Inspire Brands in Canton, Massachusetts, and the restaurant that printed your receipt is almost certainly a franchisee's — which is why an invitation appears on some receipts and not others a mile apart. Separately, the Make It Right Guarantee covers an order that went wrong, and Dunkin' Rewards handles points. Neither is the survey.
Questions people ask
How long is the Dunkin' survey coupon valid?
14 days from date of issue, per Dunkin's own FAQ. A widely copied guide says 30 days, and the company's figure is the one honoured at the counter.
Is the survey at telldunkin.com or dunkinrunsonyou.com?
Both resolve, and Dunkin' names neither. Several pages claim one replaced the other. Use whichever address is printed on your receipt.
What do I get for completing it?
One free classic donut with a medium or larger Dunkin' beverage. Cooler beverages do not count towards the condition.
Can I use the coupon on a mobile order?
No. The redemption rules state the offer is not valid on Mobile App orders, so it has to be an in-store transaction.
How long do I have to take the survey?
No window is published by the company. Guides say three days, and one says three to five. With nothing first-party to check, treat it as three.
How many digits is the survey code?
One guide says 18 and the others give no figure. Enter what is printed rather than counting to a target you read somewhere.
Can I use two coupons in one visit?
No. The limit is one coupon per customer per visit, so a second waits for another trip and its own 14 days.
Is this the same as Dunkin' Rewards?
No. Dunkin' Rewards earns points on purchases. The Guest Satisfaction Survey is separate and pays a single coupon.
