Registration Numbers

Vehicle Registration Marks and Reservation of Numbers.

Many people have craze on their vehicle registration numbers. Some of them want fancy numbers while the others want numbers according to their belief in the numerical astrology. Whatever it may, it will be interesting to know about the theory of formation of vehicle registration numbers in the state, keeping it as a unique identifier for each vehicle.

Old System.

Till the implementation of the Motor Vehicles Act 1988, we used a combination of three English alphabets followed by numerals, from 1 to 9999, to make a unique registration mark. First letter ‘K’ represents the state of Kerala, the second letter shows the series and is fixed by the Government of Kerala when the previous one was exhausted. ‘L’,’R’, ‘E’, ‘B’, and ‘C’ were the alphabets used for the second position. The alphabet in third position represents the District in which the vehicle was registered. Table below shows the alphabets used for representing each District


Thiruvananthapuram (Trivandrum)

‘T’, ‘V’


Kollam (Quilon)

‘Q’, ‘U’





Alappuzha (Alleppey)

‘A’, ‘Y’



‘K’, ‘O’






‘E’, ‘F’


Thrissur (Trichur)

‘H’, ‘R’


Palakkad (Palghat)

‘P’, ‘G’



‘M’, ‘L’



‘Z’, ‘D’





Kannur (Cannanore)

‘C’, ‘N’





State Transport Undertaking



Thus the registration marks issued in Trivandrum District were

            KLT-1 to KLT-9999, KLV-1 to KLV-9999
                            KRT-1 to KRT-9999, KRV-1 to KRT-9999
                            KET-1 to KET-9999, KEV-1 to KEV-9999

            KBT-1 to KBT-9999, KBV-1 to 9999

            KCT-1 to KCT-9999, KCV-1 to KCV- not completed


Present System

            On the commencement of the Motor Vehicles Act 1988, wef  01/07/1989, the registration mark of vehicles is formed in a new format. The Government of India has allotted ‘KL’ as the state-code to Kerala State; which forms the first part of registration mark for the vehicles registered in this state.

            The second part was a numerical District-Code starting from 01 for Trivandrum, ending at 14 for Kasargod and 15 for Sate Transport Undertaking (KSRTC).

            When three Sub Regional Transport Offices are upgraded as Rural Regional Transport Offices, district code is extended to them as 16 for Attingal, 17 for Muvattupuzha and 18 for Vadagara.


            Later, considering the exponential increase in the registration of the vehicles and difficulty in allotting groups of numbers from Regional Offices to Sub Regional offices, Government has decided to allot registration codes for every office. Code numbers 19 to 60 are allotted to each Sub Regional Transport Office.

            The last part is numerical part starting from 1 to 9999. When the number comes to 9999 a third part is introduced in between the second and last numerical parts. This third part represents the ‘series’ starting from A to Z avoiding ‘I’ and ‘O’. When the series comes to ‘Z’ new series starts from AA to AZ and then BA to ZZ avoiding ‘I’ and ‘O’.

Allotment of Registration Numbers.

            The inspecting officer examines the applications for registration and inspects the vehicles produced before him. Acknowledgements will be issued by the inspecting officer on every proper application immediately after the inspection. All the applications received in a day are entered in the computer in the afternoon. On giving a command to the computer the system will allot Registration Numbers to all the Vehicles instantly. There are no manual interventions in allotting the Registration Numbers, except for the reserved numbers. The allotted numbers can be seen from the Information Kiosk provided in the office instantly or from the office notice board. If the concerned office is connected to KSWAN the allotted numbers can be viewed online.

Fancy Registration Numbers

Some registration numbers in every series are notified by the Government as Fancy Numbers. These numbers will be allotted only on reservation. These numbers can be viewed in Number Booking menu.
