Calling Cards (also referred to as Titles and Backgrounds) are a player customization option for the Playercard that appears in every Call of Duty game since Call of Duty: Modern Warfare 2. Calling Cards take the form of stylized backgrounds that can appear with or without text on a player's nameplate when that player's name is shown in-game. Calling Cards are often paired with emblems to form the whole of an individual's playercard. Calling Cards are earned through completing challenges and general progression, external promotions, microtransactions and supply drops or bought through in-game currencies. Calling Cards were once exclusively available in the multiplayers of the respective games, but have since been included in other modes such as the campaigns and Zombies modes.
