[vc_row][vc_column][vc_column_text]Why is there no Z in number plates? What about Irish number plates? We’ll cover everything you need to know about letters in plates in this article.
At Number Plate Clinic, we want you to be well-informed about everything to do with number plates. From why there is no Z in number plates and if cameras can see 4D plates, to how 4D plates are made and if your MOT will fail if you have them.
We are your best alternative to Halfords, and would love to help you better understand number plate rules – like that green stripe on electric vehicle number plates, and why there is no Z in number plates. Lucky for you, we have articles on it all, and we’re going to go through what you need to know about Z number plates right here.
Current number plate structure rules in the UK are AA** BBB. Here, the ** represents the time point when the vehicle was first registered (e.g. 02). Way before this, number plates from 1903 could be as simple as A1 and 1A – two plates that are coincidentally owned by Prince Jefri Bolkiah of Brunei for his matching Bentley Azures.
These older number plates can be sold at the auction for hundreds of thousands, with the most expensive UK plate selling for just under $520,000 in 2014.
With seven characters allowed on number plates, vehicle owners have more choices when it comes to picking out numbers and creating personalised plates. Words can be spelled out, though there are rules for this, as well. Some examples of words that you can spell on a number plate include builder (BU11DER), boss (BO55SSX), guitar (GU17TAR), and many more.
Because of this, however, there are dozens of number plate combinations that are banned every year, with some from 2024 including OR24 SMS, SK24 NKS, and SH24 TDD.
For a number plate to be legal, you need to follow the rules set out by the government. You can find the full list of the rules and regulations you need to follow on the government website, but we’ll provide you with a quick breakdown here.
The number plates used on your vehicle, no matter the type, needs to:
Your number plate can have raised characters (3D and 4D), and it is allowed to display certain identifiers, flags, or symbols. Zero-emission vehicles may have a green flash on their plates.
Find out more about picking the right plate and dimensions for your vehicle, and whether it’s illegal to cut down a number plate or not. You can also find out if you need to declare 4D number plates for insurance purposes, so you can make sure that you’re on the right side of the law.
All UK number plates need to follow the right sizing and lettering, including the correct font (Charles Wright 2001) for their number plates. The rear plate must be yellow, while the front is white, and there can be no background patterns. All plates fitted after September 2001 must be marked with a British Standard Number, and must show the plate supplier.
Below are the rules to the correct spacing in UK number plates so that they can be picked up by ANPR:
Incorrectly spaced number plates can lead to the numbers and characters being misrepresented. If this happens, your plates will not easily be picked up by ANPR, and they will be deemed illegal. This is why it is crucial to ensure that you get your number plates from certified sellers like us – because no one wants a £1,000 fine for something that isn’t their fault.
The reason why you won’t find the letter Z on the front section number plates – or, most number plates, is because it can easily be confused with the number 2. At a glance, it could be easy to mistake one for the other, and it’s better to be safe than sorry when it comes to number plates.
Similarly, you won’t easily find number plates that incorporate ‘I’, ‘U’, ‘O’, and ‘I’ at the front/prefix area, because they are just too easy to mistake for 0 and 1. The same goes for ‘Q’, as this can easily be misread as 0 or O, though Q was used on recovered and stolen cars up until 2001 as a prefix.
You can use Z on number plates, provided they are in the last three letters of the plate (BBB). They cannot be used in the prefix area, where the vehicle’s registry date needs to be.
You can only use Z on a number plate in the BBB section of the place (remember, current plates follow the AA** BBB structure). So, you can have all different combinations that include Z on the second half of the plate without issue.
Northern Irish number plates follow a different set of rules to the rest of the UK. These plates will feature a set of letters followed by a number anywhere between 1–9999. Vehicles from Northern Ireland don’t have a year identifier, so the numbers used are dateless, making them more cost-effective and very popular.
Unlike the rest of the UK, Northern Irish cars will always have either Z or I in the first half of the number plate, which are local code letters. So, if you ever see a vehicle with a number plate that includes I or Z in the first half – you’re probably looking at a Northern Irish car.
So, why not keep an eye out for these on the road, and even try to figure out how old the vehicle is? It could be a fun game for all the car enthusiasts out there.

So, why is there no Z in number plates? There are. Z can be used in the second half of a number plate where the structure is AA** BBB. However, Northern Irish number plates must either include an ‘I’ or a ‘Z’ in the first half of their number plate, as these letters are used as local code letters.
