Since their humble begining in 1903, cherished numbers have continued to increase in popularity often adding the finishing touch to our prized posessions and very often prove to be a valuable investment.

The Motor Car Act 1903, which came into force on 1 January 1904, required all motor vehicles to be entered on an official vehicle register, and to carry number plates. The Act was passed in order that vehicles could be easily traced in the event of an accident or contravention of the law. Vehicle registration number plates in the UK are rectangular or square in shape, with the exact permitted dimensions of the plate and its lettering set down in law.

If you are buying the plates separately then you’ll need to go to a registered number plate supplier to get new number plates for your vehicle. The registered supplier will need proof of your identity, as well as proof that the registration number belongs to you. The number plate supplier will need to see at least one document from each of the lists below. This will allow the number plate supplier to confirm your name, address and entitlement to the registration number. All documents must be original, not copies.

The UK’s most expensive number plate to date is the F1 registration number purchased by a British businessman for £440,625 in 2008, though that’s just small change compared to the £7m spent by Abu Dhabi-based Saeed Khouri on the 1 number plate – officially the largest sum of money ever spent on a registration number.

The number plate 1D was bought for a record £352,000 at auction yesterday.

Tycoon Nabil Bishara won it in fierce bidding and plans to put it on his wife’s Bentley.

His £352,411 offer beats the previous £254,000 best for a DVLA sale, set by 51NGH in 2006. The DVLA’s Damian Lawson said after the auction in Claverdon, Warks: “We’re absolutely over the moon.”

Britain’s priciest car reg is F1, bought privately for £440,625 in 2008 by Afzal Kahn of Bradford, West Yorks.
