  As Prince of Wales, Charles's coat of arms was based on the arms of the United Kingdom, differenced with a white label and an inescutcheon of the Principality of Wales, surmounted by the heir apparent's crown, and with the motto Ich dien (German:, "I serve") instead of Dieu et mon droit.
  
  When Charles became king, he inherited the royal coats of arms of the United Kingdom and of Canada. The design of his royal cypher, featuring a depiction of the Tudor crown instead of St Edward's Crown, was revealed on 27 September 2022. The College of Arms envisages that the Tudor crown will be used in new arms, uniforms and crown badges as they are replaced.
