NetID and upload documents for financial aid

Does Rutgers provide NetID for accepted students? I tried https://netid.rutgers.edu/activateNetId.htm but kept on getting errors like this “We are unable to fulfill your request, either because of the information provided or a system error. Please try again”

Without Netid, how can anyone upload the requested documents for financial aid?

I have called Rutgers twice and went to the office once and got three different answers.
