My code does not work – The error message ‘Failed to redeem code’ appears

Troubleshooting Promo Code Activation in Smart Testy

If you encounter the error message ‘Failed to redeem code. Please contact portal support.’ during activation, first ensure that the code has not already been used and that it was entered correctly in uppercase letters. Pay close attention to the number 0 and the letter O, which can look very similar.

Promo codes on the Smart Testy platform are for one-time use only, so a code cannot be redeemed a second time.

If the code has never been used before, was typed accurately, and the error persists, please contact our technical support team. You can use the contact form at the bottom of the page or call us at +48 501 524 526.
