SI private plates

Private plates for the initials SI: SI in front with a matching letter behind, SI mirrored, and the prefix and Northern Irish marks that carry them, best first. These include prefix private plates such as P1 GNT and Northern Irish private plates such as SIB 206, which carry no year and fit a vehicle of any age. None has ever been on a vehicle.

Price shownThe £80.00 DVLA fee is the government’s compulsory charge for assigning a registration mark to a vehicle. It is the same wherever you buy, carries no VAT, and is inside the total price.VAT at 20% applies to the private plate itself. The net price leaves both off; the total puts them back on.Ex.

Enter your current registration mark to limit results to registration marks that you can legally assign.

A registration mark must never make a vehicle look newer than it is. The age is carried in the mark itself, so DVLA will not assign one that post-dates the vehicle.

AB76 ABC carries the 76 identifier, which is issued from 1 Sept. 2026. It cannot be assigned to a vehicle first registered as new before that date, though it can go on anything registered on or after it.

A dateless or Northern Irish mark carries no age at all, so it fits a vehicle of any age and is never hidden here.

Why these results?

Age-hiding private plates. These private plates contain your initials SI within a three-letter group, followed by a number, such as SIL 344. We favour combinations where the extra letter interferes as little as possible with your initials, particularly a narrow I. They also carry no year, so they can be used on a vehicle of any age.

Why these results?

Prefix private plates. The private plates below start with a single letter followed by a number from 1 to 999 and three letters, like P10 GNT. The first letter decides the oldest vehicle it can go on. Add your vehicle’s current registration mark above to remove registrations you cannot use.
