Your student number can be found on your student ID card. Depending on when you started at King's, your student ID number may the same or different to your 'K-number'. The student ID number is however, used differently to your K-number, which is what you use to log in to King's IT equipment and applications, and also different to your candidate number, which you use for assessments.
Your student number will also be on most official emails and letters from King's, such as Confirmation of Study letters.
