In short
- The final letter is the age identifier in a suffix registration. Its position is what separates it from a prefix plate.
- A means 1963, E means January to July 1967, and Y means August 1982 to July 1983.
- I, O, Q, U and Z do not appear in the standard year-letter sequence shown by DVLA.
- The letter identifies the registration issue period rather than the exact manufacture date.
- Dateless, Northern Irish and Q registrations need their own routes instead of this chart.
The letter only works when it is at the end. Search it below, then keep the answer as an issue window rather than turning it into a precise build date.
How do you find the year of a suffix registration?
Confirm that the registration has letters, then numbers, then one final age letter, such as ABC 123R. Enter that last letter in the finder. An R at the end means August 1976 to July 1977, while the same letter at the front belongs to the later prefix system.
The input accepts one letter and searches only the checked suffix sequence. It does not guess a result for a missing letter or interpret a whole registration. That narrow behaviour is useful because the same age letters were reused in a different position after 1983.
Use the complete UK year chart when the format is unclear or when you want to search a calendar year across suffix, prefix and current issue periods.
What is the complete UK suffix number plate year chart?
The standard chart runs from A for 1963 to Y for August 1982 to July 1983. E covers January to July 1967, then F starts the August-to-July cycle. The table follows the periods printed in DVLA INF104 rather than smoothing them into full calendar years.
| Final letter | First registration period |
|---|---|
| A | 1963 |
| B | 1964 |
| C | 1965 |
| D | 1966 |
| E | January to July 1967 |
| F | August 1967 to July 1968 |
| G | August 1968 to July 1969 |
| H | August 1969 to July 1970 |
| J | August 1970 to July 1971 |
| K | August 1971 to July 1972 |
| L | August 1972 to July 1973 |
| M | August 1973 to July 1974 |
| N | August 1974 to July 1975 |
| P | August 1975 to July 1976 |
| R | August 1976 to July 1977 |
| S | August 1977 to July 1978 |
| T | August 1978 to July 1979 |
| V | August 1979 to July 1980 |
| W | August 1980 to July 1981 |
| X | August 1981 to July 1982 |
| Y | August 1982 to July 1983 |
The wording “first registration period” matters. The age identifier limits the period represented by the registration. It does not certify the production month, trim, engine or present identity of a vehicle displaying it.
Keep the month boundary when buying parts, checking originality or ordering artwork. A car first registered in July and one first registered in August can carry consecutive letters even though they belong to the same calendar year.
What does a suffix number plate look like?
A standard suffix registration places one to three letters first, one to three numbers next and a single age letter last. ABC 123A shows the structure. The final A is the age code, while the preceding letters and numbers form the rest of the registration mark.
The suffix position is the decisive clue. A123 ABC is a prefix registration and uses its first letter for age. AB12 CDE is the current format and uses the middle number pair. ABC 123 has no suffix age letter and may be a dateless-style mark.
| Example structure | Format | Age position |
|---|---|---|
| ABC 123A | Suffix | Final letter |
| A123 ABC | Prefix | First letter |
| AB12 CDE | Current | Middle number pair |
| ABC 123 | Dateless style | No age identifier |
Character spacing in this table is descriptive, not permission to rearrange an assigned registration. The legal spacing guide explains why making a word by moving characters changes the display rather than the official mark.
Why do suffix letters change from calendar years to August?
The early suffix sequence followed calendar years from A in 1963 through D in 1966. E covered only January to July 1967, and F began the August 1967 to July 1968 cycle. That transition is why a simple letter-equals-year formula gives incomplete answers.
The issue periods should be read exactly. An E suffix belongs to a seven-month window, not all of 1967. An F suffix spans parts of 1967 and 1968. From there the August-to-July pattern continues through Y.
This change also explains why an old photograph dated only by calendar year can appear to disagree with its plate. A late-1967 car can correctly wear F while an early-1967 car wears E.
Registration timing still differs from build timing. A car could be manufactured before the day it was first registered. Use manufacturer and VIN evidence when the production date matters.
Which letters were not used in the standard suffix age sequence?
I, O, Q, U and Z do not appear in DVLA’s standard suffix year-letter table. The sequence moves from H to J, N to P, P to R, T to V and ends at Y. Do not assign years to the missing letters by alphabetical interpolation.
I and O can resemble 1 and 0. Q has a separate registration role where vehicle age or identity is not established. Whatever the historical reason for each omission, the safe modern task is to reproduce the official table rather than invent a missing year.
An unusual registration containing one of those letters elsewhere is not automatically false. The omission concerns the final suffix age position. Earlier letters in the local identifier portion follow different allocation rules.
If a seller describes “Q reg” as a year, stop and use the Q registration guide. Q does not continue the suffix chronology.
What does a suffix letter prove about a car?
It establishes an issue period for the registration mark when the format and assignment are valid. It does not prove manufacture date, model year, originality, mileage, engine, ownership history or the date on which a transferred private registration first reached that car.
Read the V5C and official history for the vehicle. Compare the VIN, maker records and physical car when identity matters. A registration is one evidence stream, not the complete biography.
The plate also cannot be used to make a vehicle appear newer than it is. A suffix mark can move to an eligible vehicle of the same age or older under the current DVLA process, but not to a younger-looking position that breaches the rule.
The private-plate age guide explains the assignment boundary. The core point is easy to reverse: an old mark can go on a newer car because it makes the car look older, while a newer age mark cannot go on an older car.
Can a suffix registration be a private number plate?
Yes. A suffix-style registration can be retained, bought or assigned as a private number when the entitlement and receiving vehicle meet current DVLA conditions. Its final letter still carries an age meaning, so the number cannot make the vehicle appear newer.
Buying plates from a supplier is not the same as acquiring entitlement. The current V750, V778 or assigned vehicle record is what matters. Do not pay for a pair of display plates as though they transfer the registration.
Use the current GOV.UK private-number steps and wait for confirmation before displaying the mark. Update the insurer and relevant payment accounts after the official registration changes.
A seller should not send certificate scans around casually. GOV.UK warns that another person could misuse the information. Confirm a legitimate transaction through the proper route.
How should a suffix registration be used on a car print?
Copy every assigned character in order, keep the final age letter in its legal position and select the car from its visible model rather than the plate alone. A print can preserve the period registration without claiming it proves the car’s build date.
A 1970s or early-1980s car may look natural with its age-related suffix, while a newer car can legally carry an older retained mark. The poster year and specification should still describe the vehicle represented, not the plate’s original issue year.
The live builder keeps registration outside the reusable artwork. This prevents one customer’s plate becoming part of the master car drawing and lets the same reviewed front serve another owner accurately.
Open a live car builder, enter the mark and review the final letter carefully. If the car body does not match a published drawing, use the custom route rather than choosing by plate age.
Which official source supports the suffix year chart?
DVLA INF104 supplies the suffix format and complete age-letter table, including the short E period and August changeover. GOV.UK supplies current private-number assignment and display rules. These pages were reviewed on 9 August 2026 and should be checked again before a registration transaction.
Read DVLA INF104 for the source table and Displaying number plates for current road-display requirements.

Questions people actually ask
- How do I find the year of a suffix number plate?
- Read the final letter in a registration shaped like ABC 123A, then match it to the suffix chart. A indicates 1963, while Y covers August 1982 to July 1983. Confirm the format before using the letter because prefix plates reused the sequence at the front.
- What year is an R suffix registration?
- An R suffix registration was first issued from August 1976 to July 1977 in the standard Great Britain sequence. The R must be the final age letter. An R at the front belongs to the later prefix system and covers another period.
- Why was there no I, O, Q, U or Z suffix year?
- Those letters do not appear in the standard suffix age sequence printed by DVLA. Some were avoided because they could be confused with numbers or other characters, while Q has a separate vehicle-identity role. Use the official sequence rather than filling alphabetical gaps.
- Does a suffix number plate prove when a car was built?
- No. It identifies the period in which that registration mark could first be issued. A vehicle can be built before first registration, and a private suffix mark may later move to an eligible older vehicle. Check the V5C and vehicle evidence for actual dates.
