Understanding Vehicle Registration in the UK

A comprehensive guide to vehicle registration numbers, their format, and what they mean.

Understanding Vehicle Registration in the UK

Vehicle registration numbers in the UK follow a specific format that tells you important information about when and where the vehicle was registered.

Current Format (2001 - Present)

The current UK registration format consists of:

  • Area code (2 letters) - indicates where the vehicle was first registered
  • Age identifier (2 numbers) - shows when the vehicle was registered
  • Random letters (3 letters) - unique identifier for each vehicle

How to Read Registration Numbers

Area Codes

The first two letters indicate the DVLA regional office:

  • AA-AN: Anglia
  • AO-AU: Birmingham
  • AV-AY: Cymru (Wales)
  • BA-BY: Birmingham
  • CA-CO: Cymru (Wales)

Age Identifiers

The age identifier changes twice a year:

  • March 1st: Uses the year (e.g., 24 for 2024)
  • September 1st: Uses the year + 50 (e.g., 74 for September 2024)

Why This Matters
