The name of Spain's state-run post office is correos. Stamps can be bought in an estanco, although certified or express mail must be sent from a post office (estafeta or oficina de correos). Postboxes in Spain are silver with red and yellow hoops. There are also red boxes for urgent mail. In Latin America correo, in the singular, means both a post office and the mail system.
