Like new rzr, NO VIN NUMBER!

I just bought a 2014 Polaris rzr xp 4
Well it had a bent Frame. So we bought a nice used one on eBay then I bought the racer tech race prep weld in gusset kit. So I had gusset kit welded in then had the frame powder coated. Then paid shop to reassemble.
So now I have a almost brand new rzr with super low miles and new "bullet proof frame.
Well it seems that when they welded the frame rails on it covered up the vin on frame I think. So now I have a badass rzr with no vin.
What do I do? Any suggestions?
