How do you play the number plate game?

The most popular UK version uses the three letters at the end of a plate. Someone reads them out, and everyone races to make a word containing those letters in the same order: RBT could be rabbit, KTN kitten. First valid word gets the point.

What do the letters and numbers on a UK number plate mean?

On plates issued since September 2001, the first two letters are the area code, showing roughly where the car was first registered. The two numbers are the age identifier, and the last three letters are random.

How do you tell how old a car is from its number plate?

Look at the two digits. A car registered from March to August carries the year, so 24 means March 2024 onwards. From September to February it's the year plus 50, so 74 means September 2024 onwards.

Which letters don't appear in the last three letters of a UK number plate?

I and Q are not used in the random three letters, because they look too much like 1 and 0. Q is reserved for vehicles whose age can't be identified.

Number Plate Game: UK Car Journey Games with Plates

The number plate game is a word race using the three random letters at the end of a UK number plate: a passenger reads them out, and everyone tries to make a word that uses those letters in the same order, so KTN becomes kitten and RBT becomes rabbit. First valid word scores. On a motorway there’s always another plate in front of you.

UK plates carry more information than most drivers realise, which gives you three more games on top of the word race.

How to read a UK plate

On any plate issued since September 2001, the format is two letters, two numbers, three letters, for example LB24 KTN.

LB is the area code. The first letter shows the region where the car was first registered: L for London, M for Manchester and Merseyside, Y for Yorkshire, S for Scotland, C for Wales (Cymru).
24 is the age identifier. Cars registered from March carry the year (24 = March 2024); from September, the year plus 50 (74 = September 2024).
KTN is random, and never includes I or Q.

Plates from before 2001 start with a single letter and look like R123 ABC. Northern Ireland plates use a different system and have no age identifier, so leave them out.

Game 1: Plate words

A passenger reads the last three letters of the car in front.
Everyone makes a word with those letters in order. Other letters can go before, between and after them: KTN gives kitten, kitchen or knitting. Ketchup fails, because it has no N after the T.
First valid word wins the point. Anyone can challenge a word; the dictionary on a phone decides.
Bonus point for the shortest word. After ten seconds, whoever found the shortest valid word scores again. For KTN, “kitten” (6 letters) beats “kitchen” (7).

Some sets, like XJV, are close to impossible. Allow a pass: if nobody finds a word in thirty seconds, move to the next car.

Game 2: Area code collection

There are 19 regional first letters in current use: A, B, C, D, E, F, G, H, K, L, M, N, O, P, R, S, V, W and Y. The car works together to spot all 19 during the journey. On a long run north you’ll often notice the mix change: more N, Y and S plates the closer you get to Scotland.

This is the closest UK cousin to the American license plate game, but it plays differently. Nineteen letters is a list you can finish in a day, and dealers register cars far from where they end up, so rare letters appear anywhere.

Game 3: Oldest car wins

Everyone watches for the oldest age identifier during one motorway stretch. A 51 plate (September 2001) beats anything newer; any plate from before 2001 beats the lot. Kids pick up the plus-50 rule within a few plates, and after that they start guessing the age of every car on the drive.

Game 4: Plate maths

A passenger reads out the two digits of the age identifier. For younger children, the first to say whether it’s odd or even scores. For confident adders, add the two digits (74 makes 11). For kids working on times tables, multiply them (74 makes 28).

Versions by age

Ages 6 to 8

Plate maths and odd-or-even. For plate words, use only the first two of the three letters, so KT can be kite or kit.

Ages 9 to 12

Plate words with the shortest-word bonus.

Teens and adults

Plate words backwards: the letters must appear in reverse order. KTN becomes NTK, so you need an N, then a T, then a K. Nutcracker works; kitten doesn’t. Expect a lot of passes.

On a long motorway run

Play plate words in rounds of ten plates, then swap to area codes for a while. The word race is intense and tires younger players after fifteen minutes.
Services car parks are the best place for the area code hunt. Walk a lap before getting back in and tick off anything new.
In slow traffic, the oldest-car game works best: you have time to read every plate around you.

When the word race stalls, it’s usually because the last few plates were unplayable. Skip three cars and take the fourth, or let the youngest player pick which plate to use.

The driver’s part

The driver never reads a plate, but they can play plate words by ear once a passenger reads the three letters aloud, since that needs no looking.
