DOE fingerprinting question

Hi all I have a school that is interested in hiring me as a substitute however they haven’t nominated me in the system and instead they want me to get fingerprinted first. I looked at Identogo and saw I needed a code. I didn’t get a code so I looked it up online, and the code was accepted. My question is will I have to redo fingerprinting if I go before being nominated and will the people at the fingerprinting place give me a hard time since I just found the code online? Thanks
