How do I send GED to college?

I'm trying to get into to college, out of state and I went to job corps like 2 years ago and gotten my GED. Now what do I do I asked them but they said to call the institute of where I gotten it. Now I'm banking on the fact that I have to call the job corps of where I went, but is there a way I can have the GED place send it? if not i'm still going to call the job corps I just want to make sure i'm not doing this wrong.
