The Coat of Arms of Carção is relevant to Jewish heritage because it includes a seven-branched candelabrum as an official heraldic element of the freguesia. In a village associated with New Christian and marrano memory, the symbol gives civic visibility to the Jewish dimension of local history.

The heraldic opinion of the Comissão de Heráldica da Associação dos Arqueólogos Portugueses was issued on 16 July 2003. The coat of arms, flag, and seal were approved by the Assembleia de Freguesia de Carção on 28 December 2003, published in the Diário da República on 20 January 2004, and registered under no. 054/2004 on 22 March 2004.

The official blazon describes a red shield with a gold seven-branched candelabrum, highlighted in black. It also includes a gold shuttle with blue thread, placed between two wavy vertical bands of silver and blue. The shuttle refers to textile work, while the candelabrum became the official heraldic sign used to represent the Jewish and marrano memory of Carção from 2004 onward.
