Master's Course Code

I am filling out the paper application form for a Postgraduate loan. In section 3.1, it requires a six digit course code for the Master's I will be studying.
I am not sure what this code is. My offer letter and the programme specification for the course both use the same seven digit code to identify the course. My offer letter also contains two CAH3 codes.
Can you advise what code I should use?

Hi there, what is the name of the university and course? Thanks, Jason
