send 成绩单 together with ??

If I send the transcripts by post, need I add piece of information, like my name, date of birth and online application usename, for the admission officer to recognize my application?  

I have the sealed envelope with my transcripts.  Since I am going to apply online, the transcripts are the only things I need to send by post.

What did your guys do? Thanks  a lot!

Thank you, JJ. I saw your suggestion too later to attach a cover letter.

I just sent them the transcripts. Hopefully they will put it in a right way. Anyone did the same like me?

One more question, after all submission, shall I send them email to confirm all things arrived? Thanks a lot!

Thank you so much. How long did you wait to get the confirmation (or online status change)? Right after the submission ?
