ER car plate: what year?

When the ER series came out, how old a ER car can be, and when its COE runs out.

The ER series came outJune 1981It was the newest series for 5 months, until ES in November 1981.

A car with an ER plate was registered in June 1981 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 ER car plate?

The ER series came out in June 1981. It was the newest series for 5 months, until ES in November 1981. So a car with an ER plate was registered in June 1981 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 ER plate?

No older than 45 years and 5 months (in November 2026), counted from June 1981, when the series came out. It can be younger: the plate only says when the number came out.

When does an ER carโ€™s COE end?

The COE system began in May 1990, after the ER series came out, so a car registered before then needed none when new. From May 1990 a new car gets a 10-year COE, renewable for 5 or 10 years at the Prevailing Quota Premium: see the latest COE prices and PQP.
