Here’s how much new number plates in Dubai will cost

Starting from 1 January 2019, Dubai's Roads and Transport Authority (RTA) will start issuing the new generation of the redesigned vehicle number plates at the time of registration renewal and the processing of plate-replacement transactions, it announced on Thursday.
As of July the same year, RTA will start the mandatory issuance of the new plates to vehicles registered in the name of public and private organisations.  
In January 2020, RTA will start the mandatory issuance of plates for vehicles registered in the names of individuals. From now and up to January 2020, the replacement of vehicle plates for individual car owners will be elective. The changing of licence plates involves a one-time cost ranging from Dh35 for the short plate to Dh50 for the long plate. 
RTA on their website shared the cost for different types of licence number plates. 

The introduction of the new generation of vehicle plates is part of RTA’s efforts to standardise the design of vehicle plates in Dubai in line with the newly designed plates featuring three elements: Dubai brand, number and code. The move is also consistent with RTA’s preparations for issuing dual code plates, especially as the stock of single-code plates is nearing exhaustion.
 

As of January 1, 2020 it is mandatory for all personal vehicles to get the new designed license plates. As for vehicles owned by private and public sectors, their license plates can be changed starting July 2019. pic.twitter.com/Rd0i1922vS
