In Wales, communities are the Welsh equivalent of civil parishes—the lowest tier of local government. Every part of Wales lies within a community, though only some have an elected community or town council. Where they exist, these councils handle very local matters and speak for residents to the county or county borough council. Like English civil parishes, communities are purely civil/administrative and are distinct from church parishes.
Post Towns in Carmarthenshire
Below is a list of post towns in Carmarthenshire, grouped by postcode area:
- SA ▸ Ammanford (SA18) ⁞ Burry Port (SA16) ⁞ Carmarthen (SA31 / SA32 / SA33) ⁞ Ferryside (SA17) ⁞ Kidwelly (SA17) ⁞ Llandeilo (SA19) ⁞ Llandovery (SA20) ⁞ Llanelli (SA14 / SA15) ⁞ Llangadog (SA19) ⁞ Llanwrda (SA19) ⁞ Llanybydder (SA40) ⁞ Newcastle Emlyn (SA38) ⁞ Pencader (SA39) ⁞ Whitland (SA34)
The UK postal hierarchy begins with broad postcode areas (such as “CB” or “M”), which are divided into smaller postcode districts (such as “CB8” or “M1”) to support accurate mail routing. Each postal address is anchored by a designated post town, the official locality name used in the UK postcode system, which operates independently from Local Authority Districts —the administrative boundaries used for council tax and local government services. Because they serve different purposes, a property’s postal address and its local authority district do not always align exactly.
