Random Wales Address Generator
A random Wales address generator produces fictional postal addresses formatted to Royal Mail conventions, using real Wales post towns and postcode districts, for use as software test data.
Wales is served by postcode areas including CF (Cardiff), SA (Swansea), NP (Newport), LL (Llandudno, covering North Wales), LD (Llandrindod Wells) and SY (Shrewsbury, which straddles the border into mid Wales). This generator draws on 22 real postcode districts across 5 post towns in Wales, formats every result to Royal Mail "Clear Addressing" rules and pairs it with a telephone number from an Ofcom range reserved for fiction. Every address is synthetic and is intended for QA automation, form validation and database seeding.

Frequently asked questions
- Are these real Wales addresses?
No. The post towns, postcode districts and preserved countys are real, but the building numbers, street pairings and recipient names are fictional and the inward half of each postcode is generated. Nothing produced here is a live delivery point, so the addresses must never be used to send post.
- Which postcode areas cover Wales?
This generator covers 4 postcode areas in Wales: CF, LL, NP, SA. Together they contain the 22 postcode districts used by the generator.
- What is a preserved county?
Wales has 22 principal areas for local government and eight preserved counties that are retained for ceremonial and some postal purposes. Addresses may use either, and Royal Mail requires neither when the postcode is present.
- Can I filter the API to Wales only?
Yes. Call GET /api/v1/addresses/random?country=Wales to restrict generation to Wales, or pass a specific post town with ?location=<slug>.
