I have to fill out a transcript release form for my counselor and it requires the address of the Academy. Is it just the return address on my letter about being an official candidate? I am guessing that is it, but I just want to make sure.
There's an admissions office address on the USNA Admissions page. Here's the link: http://www.usna.edu/Admissions/contact.htm. I don't know if this is the same address on your letter.
However, whenever some doc required a USNA admissions address, my DS used this address.
