Need Help on a pedigree/ register

I have a KC French Lop who has a pedigree paper, but on her pedigree paper I don't see a Reg#.... Is that because she might not / are hasn't been register!? On the pedigree paper it's KC Rabbitry French lop pedigree & yea haha I don't know what grade that pedigree is are if it's just a pedigree website for all pedigree's... I have looked this website up & still can't find out much but I'm more wanting to know about the register thing ! are if anyone can maybe tell me what website that can help me find out what I'm looking for... I only met the lady I got her from once & we both didn't say much but we was both in a rash but now I could shot myself for not asking more
questions!
