Questions
What year is an SJK car plate?
The SJK series first opened for bidding in August 2008. It was the newest series for 1 month, until SJL in September 2008. So a car with an SJK plate was registered in August 2008 or later: a number can be bid for after its series opens, or kept from an older car, so the car can be newer than its plate, never older.
How old is a car with an SJK plate?
No older than 18 years and 3 months (in November 2026), counted from August 2008, when the series first opened for bidding. It can be younger: the plate only says when the number came out.
When does an SJK carโs COE end?
A COE lasts 10 years from registration, so a car registered in August 2008, when the series first opened for bidding, had its first COE run to about August 2018; one registered later, later still. So an SJK car still on the road has had its COE renewed for 5 or 10 more years at the Prevailing Quota Premium: see the latest COE prices and PQP, and the PARF and COE rebates for scrapping it.
What comes after SJK?
SJL, which first opened for bidding in September 2008, then SJM in October 2008. Before SJK came SJJ (July 2008).
What letter does SJK 1234 end in?
SJK 1234 J. The last letter is a checksum worked out from the prefix and the number: SJK 1 X, SJK 88 X, SJK 8888 B. Check any SJK plate.
