How to Take the TellHappyStar Survey
The whole process takes under five minutes. Have your Carl’s Jr. or Hardee’s receipt handy, because you will need the survey code printed on it, and follow these steps:

- Keep your Carl’s Jr. or Hardee’s receipt — you will need the survey code and store details printed on it.
- Go to the official site at tellhappystar.com in any web browser on your phone or computer.
- Enter the survey code, along with the date and time of your visit from your receipt.
- Answer the questions honestly about your most recent Carl’s Jr. or Hardee’s experience.
- Write down the validation code shown at the end and bring your receipt back to redeem the offer.
What You Need Before You Start
Taking the survey is simple, but you will want to have a few things ready before you begin:
- A recent Carl’s Jr. or Hardee’s receipt with a survey code printed on it.
- A phone, tablet or computer with an internet connection.
- A few minutes of free time to answer the questions.
- Basic English or Spanish to read and respond to the survey.
What Reward Do You Get?
Here is the honest answer: the reward from the survey varies by location and by the offer printed on your receipt. TellHappyStar commonly rewards customers with a validation code — often for a free or discounted item with a qualifying purchase — though the exact deal changes over time and from one restaurant to another. After you finish, you will usually receive a code to write on your receipt and bring back on your next visit. Because the offer can change, always follow the wording on your own receipt rather than any promise made by a third-party website, and note any expiry date so you use the code in time.
TellHappyStar Survey Rules & Requirements
Before you start, make sure you meet the typical requirements. The official rules on the survey site are the final word, but in general the following apply:
- You usually need a recent receipt, often used within a few days of your visit.
- There is normally a limit of one survey per receipt and a limit per person each month.
- Participants are typically legal residents of the country who meet a minimum age.
- The validation code is tied to your receipt and has its own expiry date, so redeem it before it lapses.
- The reward usually requires a qualifying purchase on your return visit.
About Carl’s Jr., Hardee’s & the TellHappyStar Survey
Carl’s Jr. and Hardee’s are sister burger brands operated by the same company, both recognized by the smiling yellow Happy Star. Carl’s Jr. is strongest in the West, while Hardee’s dominates the Midwest and South, and both are known for their charbroiled burgers and, at Hardee’s, Made From Scratch Biscuits. TellHappyStar is the official survey the company uses to gather guest feedback, powered by a customer-experience platform that keeps your responses anonymous and sends the results back to the brand. The goal is simple: the company wants to know what is working and what is not so it can keep improving across its locations.
Why Your Feedback Matters
It is easy to assume a quick survey does not make a difference, but guest feedback genuinely shapes how restaurants operate. Brands like Carl’s Jr. and Hardee’s track survey scores closely, and consistent feedback about a specific location — a slow drive-thru, a great burger, a helpful team member — gets noticed by management. By taking a couple of minutes to answer honestly through TellHappyStar, you help improve the experience for yourself and other customers on future visits, and you get a thank-you reward in return. Honest, specific answers are far more useful than rushing through, so it is worth giving real feedback.
Common Mistakes to Avoid
A few simple mistakes can keep you from finishing the survey or redeeming your reward:
- Throwing away your receipt — without it you cannot start the survey or claim the code.
- Waiting too long — receipts and validation codes expire, so take the survey soon after your visit.
- Mistyping the survey code — double-check every digit from your receipt before submitting.
- Using a look-alike site — only use the official tellhappystar.com address, not copycat pages that promise big prizes.
- Forgetting to write down the validation code — note it on your receipt before you close the page.
What to Do If the Survey Isn’t Working
Ran into a problem? Most issues are quick to fix:
- Double-check the survey code and other numbers from your receipt for typos.
- Make sure your receipt is recent — older receipts may no longer be valid.
- Try a different web browser or device, or clear your browser cache and cookies.
- Confirm you are on the official tellhappystar.com address and not a look-alike site.
- If the code still will not work, check your receipt for an alternate link or contact Carl’s Jr. or Hardee’s customer service.
How Long Does the Survey Take & Is It Safe?
The TellHappyStar survey takes about three to five minutes to complete, and it asks only about your visit — the food, the service, the cleanliness and your overall satisfaction. The official site is legitimate and does not ask for sensitive personal or financial information to take the survey, so you should never enter card details or passwords. If a page claiming to be the survey asks for payment or banking information, that is a red flag that you are on a scam site rather than the official TellHappyStar survey, and you should close it immediately.
