UK Vehicle Registration Mark formats

Since 1960, the UK’s vehicle registration marks have gone through three main formats, each designed to provide a structured system for identifying vehicles while indicating their approximate age.

1. Suffix System (1963–1982)

This system introduced an age identifier at the end of the registration plate.

Format:

AAA 123A

AAA – Area code (identifies the location of the vehicle’s original registration).
123 – Random serial number.
A – Year letter (indicates the year of first registration).

Year Letters:

1963: A
1964: B
1965: C
1966: D
1967: E
1968: F
1969: G
1970: H
1971: J
1972: K
1973: L
1974: M
1975: N
1976: P
1977: R
1978: S
1979: T
1980: V
1981: W
1982: X
1983: Y

Example:
ABC 123D → Registered in 1966.

2. Prefix System (1983–2001)

The year identifier was moved to the start of the registration mark.

Format:

A123 ABC

A – Year letter (indicates the year of first registration).
123 – Random serial number.
ABC – Area code (location identifier).

Year Letters:

1983: A
1984: B
1985: C
1986: D
1987: E
1988: F
1989: G
1990: H
1991: J
1992: K
1993: L
1994: M
1995: N
1996: P
1997: R
1998: S
1999: T
1999 (Sep): V
2000 (Mar): W
2000 (Sep): X
2001 (Mar): Y

Example:
P123 XYZ → Registered in 1996.

3. Current “New Style” System (2001–Present)

Introduced in September 2001, this format uses numbers to represent the vehicle’s registration date.

Format:

AA51 ABC

AA – Area code (identifies the DVLA office where the vehicle was first registered).
51 – Year identifier (tells when the vehicle was registered).
ABC – Random letters.

The year identifier changes twice a year:

March – August: The number is the last two digits of the year (02 for 2002, 03 for 2003, etc.).
September – February: The number is the year plus 50 (52 for 2002, 53 for 2003, etc.).

Example Interpretations:
AB02 XYZ → Registered between March–August 2002.
CD52 LMN → Registered between September 2002–February 2003.
EF23 PQR → Registered between March–August 2023.
GH73 UVW → Registered between September 2023–February 2024.
