It is a Samnite shield; a top band shows the sea, with a boat sailing very simply (it represents the work of fishermen) and the sun. On the lower band, on the red bottom the worker bee is depicted, to signify the laborious nature of Porto Sant'Elpidio's inhabitants. On the top of the shield is the crown to the five towers (they represent the commune) that were approved on 19 May 1965 at the site of the crown to nine blackbirds after the independence from Sant'Elpidio a Mare.
