But now you're potentially screwing up an application for the real person with that SSN. So if that person now tries to open a new application with the first SSN you entered, he or she cannot because you already took it. You should probably contact Cadet Command via email or phone (not sure address/number, other people here know them), and advise them of the situation. It is highly unlikely in the grand scheme of things that the real holder of that SSN will apply for an AROTC scholarship this year, just in terms of how many SSNs there are as compared to how many people apply for scholarships each year, but you never know.
