Questions
What year is an SJH car plate?
The SJH series first opened for bidding in June 2008. It was the newest series for 1 month, until SJJ in July 2008. So a car with an SJH plate was registered in June 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 SJH plate?
No older than 18 years and 5 months (in November 2026), counted from June 2008, when the series first opened for bidding. It can be younger: the plate only says when the number came out.
When does an SJH carโs COE end?
A COE lasts 10 years from registration, so a car registered in June 2008, when the series first opened for bidding, had its first COE run to about June 2018; one registered later, later still. So an SJH 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 SJH?
SJJ, which first opened for bidding in July 2008, then SJK in August 2008. Before SJH came SJG (May 2008).
What letter does SJH 1234 end in?
SJH 1234 A. The last letter is a checksum worked out from the prefix and the number: SJH 1 L, SJH 88 L, SJH 8888 S. Check any SJH plate.
