If you have been provided with a 20 character voucher code from your place of study or other organisation, simply add the code when prompted on the 3rd step of the application process, as highlighted in blue below;
Some voucher codes will have been prepaid by your place of study to provide you with a free TOTUM card. Other codes will be used solely to verify you are a student. Your place of study will specify whether the code you have been provided is for verification purposes or if it is to provide you with a free TOTUM card.
If you have a 5 digit access code then please see the following article for how to use it: https://help.totum.com/hc/en-gb/articles/360002066677-How-to-redeem-a-5-digit-verification-code
