Redeeming an existing registration works as follows:
Call up the following page in a browser: https://www.babbel.com/coupons/new
If you are not already logged in, login now. The Redeem a Voucher page is displayed.
Choose the language you want to learn, enter your coupon code, and then click Redeem Now.
On the next page, certain coupons will show an option to upgrade to an all-language subscription. If you don't want this option, click No thanks.
PLEASE NOTE:
After the first, discounted payment period, the upgrade continues as a regular Babbel subscription, so it is automatically renewed at the standard price until it is canceled. Details can be found in the booking confirmation email sent to the registered email address.
