Mailing Addresses for Duke, Cornell, UVA??

Does anyone for sure know the mailing addresses for Duke, Cornell, and University of Virginia? On their websites, Cornell gives 2 different addresses (410 thurston and 349 pine tree) and both Duke and UVA only give the P.O. Box #.

I’m applying undergraduate first-year and I need to send in my rec. letters. Just a little confused here – I appreciate any help y’all can offer! Thanks.

@dtxstudent Wouldn’t rec letters be submitted on-line (such as via Naviance) by your HS college counselor or the college counseling office or by the teachers themselves? Also, seems unusual that you would have a copy of the rec letters – typically students waive their rights under FERPA, which I think colleges prefer.

Shouldn’t your high school GC be sending that information directly?
