Sending Application Fee waivers, high school transcripts

So I sent my transfer application fee waiver (NACAC) to a school I’m applying to as the directions said, but I realized I never wrote my common app ID anywhere (the instructions never told me to write that anywhere). It has my name and address and stuff like that but no ID number or anything, will that negatively affect my application? Do schools generally let us know if they received such documents? I literally just sent the fee waiver application and that’s it, no other extra notes saying what the contents included or anything.

Also I have to send my high school transcripts but i received it in a sealed envelope. Is it fine to just submit it like that, without writing my common app ID anywhere? They’ll figure it out, right? Do schools typically send confirmation that they’ve received your college reports/transcripts/ect.?

My name isn’t super common or anything so I’m not necessarily worried about that but perhaps I’m being a bit paranoid lol. I’m guessing schools receive thousands of these documents and they won’t even have an idea if I’m a freshman or transfer applicant until they open them and read the documents…I just hope it doesn’t get lost or tossed into the freshman pile (im a transfer student).

Is there order to the madness?
