Cardiff is in South East Wales, Wales, with a population of around 372,000. Local landline numbers carry the 0029 dialling code — Phena can give your business a fresh 0029 number from the dashboard, or forward your existing one to the AI agent. Most callers know the area as the home of the Principality Stadium.
