Questions
What year is an SDY car plate?
The SDY series first opened for bidding in March 2003. It was the newest series for 1 month, until SDZ in April 2003. So a car with an SDY plate was registered in March 2003 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 SDY plate?
No older than 23 years and 8 months (in November 2026), counted from March 2003, when the series first opened for bidding. It can be younger: the plate only says when the number came out.
When does an SDY carโs COE end?
A COE lasts 10 years from registration, so a car registered in March 2003, when the series first opened for bidding, had its first COE run to about March 2013; one registered later, later still. So an SDY 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 SDY?
SDZ, which first opened for bidding in April 2003, then SFA in May 2003. Before SDY came SDX (January 2003).
What letter does SDY 1234 end in?
SDY 1234 G. The last letter is a checksum worked out from the prefix and the number: SDY 1 T, SDY 88 T, SDY 8888 Z. Check any SDY plate.
