112 is Spain's single, free, 24/7 emergency number covering medical, police, and fire services, and is valid across the whole EU. It can be dialed from any landline, mobile (even without credit or signal), VoIP device, or public payphone, and operators can assist in 50+ languages including English. The 112 operator acts as a central dispatch hub, routing calls to the appropriate service: local or National Police, Guardia Civil, medical/ambulance teams, fire brigades, mountain rescue, maritime rescue, or civil protection. Call-handling is delegated to 19 separate regional (autonomous community) services, though the number itself is uniform nationwide.
