Wales

Wales, located to the west of England on the island of Great Britain, is celebrated for its rugged mountains, sweeping coastlines, and rich cultural heritage. The country is home to Snowdonia National Park (Eryri), the Brecon Beacons (Bannau Brycheiniog), and over 600 castles — more per square mile than anywhere else in the world. Its capital, Cardiff, is a vibrant centre for government, sport, and culture. Welsh identity is deeply rooted in the Welsh language, music, and festivals such as the Eisteddfod.

Wales is one of the four nations of the United Kingdom and has a devolved government — the Senedd Cymru/Welsh Parliament — in Cardiff, which has powers over areas such as health, education, transport, and local government. Administratively, Wales is divided into 22 local authorities, covering both densely populated urban areas and extensive rural regions. From the industrial heritage of the South Wales Valleys to the scenic landscapes of Pembrokeshire and Anglesey, each area has its own distinct character.

Principal areas of Wales

The 22 local authorities in Wales are single-tier councils responsible for all local services, including education, planning, social services, and waste management. They range from large cities such as Cardiff, Swansea, and Newport to rural counties like Powys and Ceredigion.

A Local Authority District (LAD) is a statistical geography used by the Office for National Statistics (ONS) to describe areas governed by local authorities. LADs include non-metropolitan districts (often called district councils), metropolitan districts, London boroughs, unitary authorities, council areas in Scotland, and local government districts in Northern Ireland. In total, there are 361 Local Authority Districts across the UK. A full nationwide list is available in the List of all Local Authority Districts in the UK.

Post towns are a key part of the UK postcode system and are used to organise mail delivery. They are not administrative areas and do not define council boundaries. Some post towns are very large and broadly align with major urban areas, while many others are smaller towns that sit within a single Local Authority District. In some cases, a post town may also span more than one Local Authority District. This difference in purpose and scale is why the UK has far more post towns (around 1,500) than local authority districts (361). For a nationwide overview, including postcode coverage for each post town, see the UK Post Towns Directory.
