Which police force has authority across the whole Spanish territory and in the cities?

✓ La Policía Nacional

The Policía Nacional (the national police), formerly called the Cuerpo Nacional de Policía, depends on the State and works across the whole country, above all in the cities. It takes care, for example, of the DNI (national identity card), the passport and the police stations. The Mossos d'Esquadra (Cataluña) and the Ertzaintza (País Vasco) are police forces of comunidades autónomas, and the local police depend on the ayuntamiento (town council). An easy way to remember: national equals the whole territory, regional equals one comunidad.
