I think I made a mistake on my ID Number

<p>On my application I think they asked for student ID. I thought this meant that it was your ID number you’ve had since middle school… the 6 digit one. But I read somewhere that its not that number, and instead its the one thats on your PSAT? Is this true? </p>

<p>What should I do if I’m wrong?
I’m freaking out ahh</p>
