Everyone who is clicking of RUC code generation after AIIMS website login is getting message like you have already generated RUC code, this has led to rumors that perhaps previous RUC code would do, but AIIMS has categorically stated in there press release the previous RUC won’t be valid, so most probably it is just a technical glitch, most probably they have yet not fed new RUC into there system, we have to wait and watch, they always ask for new RUC in every exam.
