Can I put a Sianna number plate on any vehicle?

Under DVLA rules, a personalised plate cannot make a vehicle appear newer than it is. Dateless Sianna plates (no year identifier) can be assigned to a vehicle of any age. Prefix-style and current-style plates can be assigned to any vehicle first registered on or after the plate's own issue date. Each plate's individual listing on NewReg shows the eligibility rules for that specific registration.

Does NewReg price-match Sianna number plates?

Yes. NewReg operates a price-match guarantee across every plate listed. If you find the same Sianna-associated registration legitimately advertised cheaper by another UK dealer, we will beat that price. The guarantee covers the plate cost, VAT, and the DVLA transfer fee.
