PVC and PCC are not same, they are issued on different letterheads and signed by different authorities. PVC is signed by the local Commissioner of Police, while PCC is signed by the PSK authority. But both are issued for the same reason and have the same validity. CIO and NDVO accepts both PVC and PCC. The CIC website states "Applicants should contact the local Senior Superintendent of Police/ Superintendent of Police/ Commissioner or Deputy Commissioner of Police, the Additional Commissioner of Police, or the Station House Officer (Police clearance certificate issued by the Regional Passport Office are also acceptable.)"
I submitted a PVC and not a PCC... no issue at all... go ahead and submit a PVC if it works for you
