A car with an SDD plate was registered in May 2000 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.

Questions

What year is an SDD car plate?

The SDD series came out in May 2000. It was the newest series for 2 months, until SDE in July 2000. So a car with an SDD plate was registered in May 2000 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 SDD plate?

No older than 26 years and 6 months (in November 2026), counted from May 2000, when the series came out. It can be younger: the plate only says when the number came out.

When does an SDD carโ€™s COE end?

A COE lasts 10 years from registration, so a car registered in May 2000, when the series came out, had its first COE run to about May 2010; one registered later, later still. So an SDD 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 SDD?

SDE, which came out in July 2000, then SDF in August 2000. Before SDD came SDB (March 2000).

What letter does SDD 1234 end in?

SDD 1234 S. The last letter is a checksum worked out from the prefix and the number: SDD 1 D, SDD 88 D, SDD 8888 J. Check any SDD plate.
