No mine car is older than 2019 and i think some process changed recently in 2023, My Hyundai dealership is putting entire onus on me, he says no customer has come with such request yet to them, though i get my car serviced from them and i see many cars with different State regn no, and still with old No plate, not sure how are others dealing with this issue.This was in Sept 2023: I tried ordering HSRP from VW dealership. They said the system is not able to take requests for my car registered back in 2015, only vehicles registered after 2019 or something they were able to get.
So I just ordered online and fitted HSRP myself. No validation on any portal was done. The HSRP has proper hologram and sr. no., it's not IND plate which local mechanics try to pass off as HSRP.
Check if that's the case with Hyundai too. Even if you order from some 'official source', dealership might not be able to do anything on portal for you.
