Pradesh, Bihar and Andhra Pradesh respectively), are registering vehicles under their new two-letter codes, while the old numbers registered in the RTO offices of these states under the RTO code of the parent state still stay valid. In 2007, the state of Uttaranchal was renamed as Uttarakhand, thus the state code changed from UA to UK. In 2011, the state of Orissa was renamed as Odisha, thus the state code changed from OR to OD. The Government of India, Ministry of Road Transport and Highways, the nodal ministry, has formulated strict specifications and enforcement rules for the new High Security Registration Plates (new number plates). The states have recently started introducing them in a phased manner. This standardisation, along with strict enforcement, is expected to bring about a change in law enforcement and in the registration process of vehicles in the country. The amount of taxes to be paid when purchasing and registering a car are chosen by the state or union territory, with the latter tending to have lower taxes. In particular, Puducherry is known for its low taxes, with many luxury cars being registered there by residents of other places to save money, sometimes fraudulently, leading to crackdowns by states affected by revenue loss in recent years. Current codes The list of two-letter codes for states and Union Territory codes is as follows: Former codes List of codes no longer in use: Part 2: District Number Since all states have two or more districts, the district is in charge of registering the vehicle. A vehicle bears the registration of the district in which it is bought rather than the district of residence of the owner. In many states, officials insist that the plates be changed to the local numbers if the owner shifts residence. The number of districts in the state need not equal the number of permutations of the district field of the licence plate. Often, in districts with large cities the geographical district can be split into two or more administered regions, each governed by an RTO. A case is the 11 RTOs of Bengaluru Urban District in the state of Karnataka which has the plate bearings KA 01 for HSR Layout (Bengaluru Central), KA 02 for Rajajinagara (Bengaluru West), KA 03 for Kasturinagara (Bengaluru East), KA 04 for Yeshwanthapura (Bengaluru North), KA 05 for Jayanagara (Bengaluru South), KA 41 for Kengeri (Bengaluru West Suburban), KA
