RTO India — Delhi ncr permit - gurgaon

Address:

Gurgaon, Haryana, 122001

We purchased a cng car from gurgaon in jun 2016 for taxi purpose in delhi ncr region.
But delhi ncr permit not issuing by gurgaon rto and saying the words you can only run the taxi out of ncr region with all india permit.
So please inform us is it right ncr region vehicle not allowed to run in ncr region(Delhi, gurgaon, noida, ghaziabad)?
