If you’re trying to redeem your free GED Ready voucher from Onsego and see an “Incorrect Code” message, don’t worry—it’s a common mistake and easy to fix.
When you receive the “Incorrect Code” message while redeeming a GED Ready voucher from Onsego, it means that you mistakenly pasted the code into the Coupon box instead of the Voucher/Promotion Code box.
You must paste this code into the “Voucher/Promotion Code” box.
This situation usually happens when students are not logged into their GED.com accounts and miss the “Voucher/Promotion Code” field
Here’s what to do:
-
Log in to your GED.com account.
-
Click on the “Study” button.
-
On the next page, click on “See if I’m ready.”
-
You will be redirected to the product page, where you can choose your subject. Then you can choose your language: English or Spanish.
-
On the next page, you will see ” Do you need to redeem a voucher?” Choose “Yes, I need to redeem a voucher,” then follow the directions on the screen.
