The History of UK Number Plates (1903 to Present)
UK number plates began on 1 January 1904, when the Motor Car Act 1903 required every motor vehicle to be registered with its local council and display its registration. Since then the system has moved through four main formats: dateless (1903 to the mid-1960s), suffix (1963 to 1983), prefix (1983 to 2001) and the current style used since September 2001.

The Motor Car Act of 1903: The Birth of UK Registrations
The first official UK number plates came into force with the Motor Car Act of 1903, which became law on 1st January, 1904. This legislation required all motor vehicles to be registered with local councils and display visible registration numbers. It also introduced driving licences, speed limits, and vehicle braking regulations.
Some councils began issuing number plates slightly earlier, in late 1903, ahead of the new rules coming into force.
Early Number Plate Format (1903–1932)
From 1903, the original format featured one or two letters followed by up to four numbers, such as A 12 or AB 1234. The letters identified the issuing local authority – for example, 'A' indicated a London issue.
These early plates were dateless, meaning they didn't indicate the year of registration. This makes them desirable for personalised use today, as they can conceal a vehicle's true age. The dateless system remained in place until 1st January, 1965. See our guide to dateless number plates.
What was the first UK number plate?
Many believe that 'A 1' was the first number plate issued in the UK. In fact, it was simply London's first registration, issued to Earl Russell. The actual first UK plate issued was 'DY 1', registered by Hastings Borough Council on 23rd November, 1903. 'Y 1', issued on 25th November, 1903 by Somerset County Council, was the first single-letter, single-digit registration.
1932: A New Dateless Format Introduced
By the early 1930s, available combinations were running low. In July 1932, the format was updated by adding a prefix letter before the existing two-letter area code and limiting numbers to a maximum of three digits. Plates now followed a structure like ABC 1 or DEF 234, with the second and third letters still identifying the issuing authority and the first acting as a serial prefix. This updated format retained the six-character limit and continued to be dateless.
The Suffix Format (1963–1983): Introducing Year Letters
With rising vehicle ownership in the 1960s, even the revised format struggled to keep up. A new national system introduced a year-identifying suffix letter at the end of the plate.
The national scheme was introduced in August 1962, but the first suffix registration, AHX 1A, was issued by Middlesex in February 1963. Other areas followed during 1963 and 1964, and the suffix became compulsory on 1st January, 1965. Plates took the form ABC 123A, where the suffix 'A' indicated 1963, 'B' meant 1964, and so on. Letters I, O, Q, U, and Z were excluded from the suffix cycle. See our guide to suffix number plates.
Why did the year letter move to August?
Because the suffix changed each January, many buyers delayed purchases to get a newer plate. To balance this, the year changeover was moved to August 1st starting in 1967, with 'E' applying from January to July 1967, and 'F' from August onward.
Other Key Changes in the 1960s and 1970s
- 1967: Introduction of retroreflective plates under British Standard BS AU 145. These used white plates at the front and yellow at the rear, improving visibility.
- 1973: Reflective number plates became mandatory for all newly registered vehicles.
- October 1974: Vehicle registration moved from local councils to the Driver and Vehicle Licensing Centre (DVLC) in Swansea, which was renamed the Driver and Vehicle Licensing Agency (DVLA) in April 1990. Vehicle registrations were now centralised, with local Vehicle Registration Offices (VROs) replacing council-based systems. While many area codes remained, they no longer referred to councils but to DVLA offices.
The Prefix Format (1983–2001): Reversing the Structure
By 1983, the suffix system reached its limit. The solution was the prefix format, which placed the year identifier at the beginning.
The new structure looked like A123 BCD, starting with 'A' in August 1983 and changing every August until 1999, when new letters began to be issued twice a year, in March and September, ending with 'Y' from March to August 2001. Again, letters I, O, Q, U and Z were skipped to avoid confusion.
How a prefix registration is made up
- Prefix letter: Year of issue (e.g. A = 1983, B = 1984, etc.)
- Number: From 21–999 (1–20 reserved for later DVLA Personalised Plates)
- Three letters: The final two identify the registration area
Examples include A23 ABC, D456 EFG, and H789 JKL. See our guide to prefix number plates.
2001 to Present: The Current Vehicle Registration System
The current UK number plate system was launched on 1st September 2001. Designed for clarity and longevity, it features seven characters: LLNN LLL.
Local Memory Tag (First Two Letters)
- Identifies the area where the vehicle was first registered
- First letter = general area (e.g. L = London, M = Manchester)
- Second letter = specific DVLA office (despite all local offices closing by 2013)
- Letters I, Q, and Z are not used
See what your number plate's area code means for the full list.
Age Identifier (Two Digits)
Indicates when the vehicle was registered:
- March–August: Last two digits of the year (e.g. 18 = March 2018)
- September–February: Add 50 (e.g. 68 = September 2018)
To decode any registration's age, see what year is my registration?
Random Letters (Last Three)
- Randomly generated to uniquely identify each registration
- Letters I and Q are excluded, and offensive combinations are filtered out
Examples include AB51 CDE and FG68 HJK.
Special and diplomatic registrations
Alongside the mainstream formats, the UK also issues distinct registrations for foreign missions. See our guide to UK diplomatic number plates for the full list of country codes and what the D and X letters mean. Vehicles whose age or identity cannot be confirmed are given Q plates, and Northern Ireland has always had its own registration system.
Frequently asked questions
When did number plates start in the UK?
Registration became compulsory on 1 January 1904 under the Motor Car Act 1903. Some councils began issuing registrations in late 1903, the first being DY 1 in Hastings on 23 November 1903.
When did yellow number plates start?
Reflective plates, white at the front and yellow at the rear, were introduced in 1967 and became compulsory on newly registered vehicles in 1973. Before that, plates had white or silver characters on a black background.
When did the current number plate system start?
On 1 September 2001, with 51 plates. The age identifier changes every March and September, and the next change is to the 27 plate on 1 March 2027.
