Questions
What year is an SGQ car plate?
The SGQ series first opened for bidding in November 2006. It was the newest series for 1 month, until SGR in December 2006. So a car with an SGQ plate was registered in November 2006 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 SGQ plate?
No older than 20 years (in November 2026), counted from November 2006, when the series first opened for bidding. It can be younger: the plate only says when the number came out.
When does an SGQ carโs COE end?
A COE lasts 10 years from registration, so a car registered in November 2006, when the series first opened for bidding, had its first COE run to about November 2016; one registered later, later still. So an SGQ 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 SGQ?
SGR, which first opened for bidding in December 2006, then SGS in January 2007. Before SGQ came SGP (October 2006).
What letter does SGQ 1234 end in?
SGQ 1234 M. The last letter is a checksum worked out from the prefix and the number: SGQ 1 A, SGQ 88 A, SGQ 8888 E. Check any SGQ plate.
