Vehicle registration plates of the Republic of Ireland
In the Republic of Ireland, vehicle registration plates are the visual indications of motor vehicle registration – officially termed "index marks" – which it has been mandatory since 1903 to display on most motor vehicles used on public roads in Ireland. The alphanumeric marks themselves are issued by the local authority in which a vehicle is first registered.
Format and specifications
The current specification for number plates is the format YYY–CC–SSSSSS. Those issued from 1987 to 2012 had the format YY–CC–SSSSSS. The components are:- YYY – a three-digit year based on date of first registration and not necessarily agreeing with the official model year of the car as referenced by the eleventh VIN digit
- * YY from 1987–2012 – a two-digit year
- CC – a one- or two-character county/city identifier.
- SSSSSS – a one- to six-digit sequence number, starting with the first vehicle registered in the county/city that year/period.
The current regulations are set out in the Vehicle Registration and Taxation Regulations, 1999, as amended by the Vehicle Registration and Taxation Regulations 2012. These prescribe the format, dimensions and technical specifications of registration plates to be displayed on vehicles. They substitute the First Schedule of the Vehicle Registration and Taxation Regulations, 1992 to allow additional characters to be displayed on the registration plate and to ensure that these are displayed in the correct position and proportion. The changes were necessary to cater for increases in the number of car registrations.
Unlike legal requirements in all other European countries, a standard uniform character font is not required. The rules simply require legible black sans serif characters, no more than 70 mm high and 36 mm wide with a stroke width of 10 mm, on a white reflective background. The result is that a large variety of perfectly legal font styles may be seen, on either pressed aluminium or acrylic plates, both of which are allowed. Despite the rather relaxed lack of a specified font, the hyphen between the lettering must lie between the minimum dimensions of 13mm x 10mm or the maximum dimension of 22mm x 10mm. Vehicle owners may be fined if the plate's format does not meet the requirements, and the vehicle will fail the mandatory periodic National Car Test.
A vehicle's number plate is determined when it is first registered, the county/city code being taken from the first owner's postal address. Registration remains fixed on the one vehicle until it is de-registered, and cannot be transferred to other vehicles.
Current implementation
Sequence numbers may be reserved on completion of form VRT15A and payment of €1,000.- Most registration numbers can be reserved, with the exception of the first number of each year issued in Cork, Dublin, Limerick and Waterford as these are reserved for the respective mayor/lord mayor of these cities.
- Luxury cars with numeric names are often registered with a matching, usually pre-reserved sequence number: for example 06-D-911 on a Porsche 911 or 06-D-750 BMW 750 and 08-D-89 for an Aston Martin DB9.
- Dublin radio station FM104 tend to register their vehicles with reserved number sequences ending with "104", e.g. 05-D-38104.
- "ZZ", administered by the AA Ireland as agents for the Revenue Commissioners, is given to registrants who are based outside the state and who only intend keeping the vehicle within the Republic of Ireland for a period not exceeding one month. This form of temporary registration is usually used for vehicles that are purchased within the Republic of Ireland but exported by its new owner to another sovereign state directly after purchase. The format of the code is ZZ followed by a five digit number.
- "ZV", which can be selected as an alternative to the current scheme when registering a vehicle older than 30 years for the first time in the Republic of Ireland.
Special formats
Vehicles registered to the Irish Defence Forces have plates with silver letters on black background. These do not feature the Irish-language county name.
Trade plates have plates with white letters on dark green background.
Diplomatic plates are very similar to civilian format, except the small "CD" between index mark code and serial number.
Index mark codes
The city codes are a single letter, the initial letter of its English-language name. Most county codes use the first and last letters of the name county. For example, Sligo is SO. The exception to this is the "D" code which is used for County Dublin which is co-extensive with and is in use for the counties of Fingal, South Dublin and Dún Laoghaire–Rathdown and Dublin city. Other exceptions are:- Where the county shares its registration function with the city of the same name, in which case both use the single-letter code. An example of this is County Cork, which shares the same name with Cork City, and takes the code "C".
- Where a conflict exists, i.e. Kerry is KY, so Kilkenny is KK; and County Waterford was WD, so Wexford is WX.
- County Tipperary is T. This is because the county was, until 2014, divided into North and South.
Current index mark codes
Note: in the case of Counties Limerick, Tipperary, and Waterford, where a vehicle has been first brought into use in another country prior to 1 January 2014 and is subsequently imported into and registered in Ireland, the codes L, LK, TS, TN, W, and WD as formerly applicable continue to be issued for such vehicles. This is to maintain the integrity of the numbering system in place for the years prior to 2014.Former index mark codes

EU standardised vehicle registration plates
The Republic of Ireland first introduced the now common blue European Union strip on the left-hand side of the number plate in 1991, following the Road Vehicles Regulations statute of 1990. A similar band was adopted by Portugal in 1992 and by Germany in 1994 and was standardised across the EU on 11 November 1998 by .History
From 1903, the system used in Ireland was part of the original British system of identifiers. This was superseded in the Republic of Ireland on 1 January 1987.A two-letter code containing the letter I was allocated to each administrative county in alphabetical order, with the initial registration format being the code followed by a sequence number from 1 to 9999, as in Great Britain. The codes allocated ran from IA to IZ, then from AI to WI, with the letters G, S, and V skipped as these were intended for Scotland. In 1921, shortly before the creation of the Irish Free State, Belfast and Dublin City completed their original marks and thus took the next available codes, XI and YI respectively, with Dublin City then taking ZI in 1927. After this, most other codes with Z as the first letter were allocated in alphabetical order, starting with single-letter Z – the only one-letter code used in Ireland – for County Dublin.
In February 1952, a joint motor taxation authority was set up for Dublin City and county, and their codes were merged. Two years later, with all possible codes allocated, a new format was introduced with a serial letter added before the code, and the sequence number running only to 999. The Dublin joint authority was the first to adopt this format when it issued ARI 1 in May 1954, and each county followed suit once all its two-letter combinations had been issued. In the case of counties with more than one code, all the three-letter marks for the first allocated code would be issued, then all such marks for the second code, and so on.
G, S and V were not used as serial letters at first, while Z was not used before a code starting with that letter, so as to prevent any clashing with ZZ temporary registrations. Several other three-letter marks were not issued through oversight or because they were deemed offensive, and the single-letter Z code was left out of this format as a serial letter would have created a duplicate of an existing two-letter code, particularly one used in Northern Ireland.
Initially, all number plates had been black with white or silver characters, but in 1969 the option of black-on-white at the front and black-on-red at the rear was introduced.
In February 1970, the Dublin joint authority exhausted all its three-letter combinations and thus began issuing "reversed" registrations, starting with the original two-letter codes in order of allocation. These were followed from July 1974 onwards by the three-letter marks, issued in the same manner as for the forward versions. Again, other counties followed this example over time. Also in 1974, Cork followed Dublin's example of setting up a joint motor taxation authority for city and county, though their codes were not merged until August 1985.
In 1982, with Dublin and several other counties having exhausted all possible combinations of their original codes, it was decided to allocate the skipped codes containing G, S and V to these counties. In the cases of these codes, the forward three-letter combinations were issued first in the same manner as before, followed by the forward two-letter combinations.
Under this system, Irish vehicle registration marks could be transferred to Britain for re-registration on other vehicles, even after Irish independence, and even though they could not be re-used within Ireland. The letter I in many combinations made these attractive for collectors, and indeed the Kilkenny issue VIP 1 has fetched a record price at auction. Since the introduction of the current system in 1987, such exports have been impossible, even for old-format registrations, although those already exported may still be re-transferred.
The 1987 system allocated single-letter codes to the county boroughs and two-letter codes to the other counties. Normally these are the initial and final letter of the English-language name of the county. Until 1991, all plates under this system consisted solely of black characters on white, on both front and rear. However, in that year, the blue EU identifier and the official Irish language name of the county were added, the latter as a result of the controversy arising from using English as the basis, described by Conradh na Gaeilge, an organisation which promotes the Irish language in Ireland and worldwide, as "a fiasco".
Vehicles first registered outside the state before 1987 are allowed to be re-registered using only the current system, with a year number preceding 87 – for instance, a vehicle from 1964 re-registered in Meath would have 64-MH at the start of its registration.
In 2013, the year was changed to a 3-digit year with the third digit being 1 for January to June and 2 for July to December, for example, 131 for January–June 2013 and 132 for July–December 2013. The decision to change the year was based partly on superstition about an unlucky '13' registration, but also to boost sales in the second half of the year.
Pre-1987 mark codes
The first codes were allocated in 1903, when all of Ireland was still part of the United Kingdom. The codes were based on the alphabetical order of counties and county boroughs as they were named at the time. King's County and Queen's County were renamed Offaly and Laois respectively following the independence of most of Ireland as the Irish Free State. Counties and county boroughs in italics are in Northern Ireland and still use the 1903 system.Codes with the letters G, S and V were reserved until the 1980s, when they were taken by counties that had exhausted all the combinations for their original codes.

On 1 January 1987, a completely new registration plate system was introduced for new vehicles. It consisted of a white plate with black letters, front and rear. The first two numbers were the year letter followed by the initial of the county, in this case, followed by a random number eg 87 D 1,87 C 2, 87 Lk 3, etc.
Vehicles older than 1987 imported into Ireland from 1987 were not given age-related numbers from the old system but were included in the new system. Their initial year number and county would be registered as 67 D 1 This would state the year of its first registration or manufacture outside the state but since 2011 these numbers have begun at 120000 which is not historical or authentic. Other examples would include that 1977 cars that have 77 number plates, 1978 with 78 number plates, 1979 with 79 number plates or 1980 with 80 number plates and so on. Volkswagen Beetle cars that were imported as knock-down kits from Mexico and assembled up to the mid-2000s were registered in Ireland on original Irish reg chassis having pre-1978 number plates.
