The official seal of Cebu City, just like any other official seals of local government units in the Philippines, underwent several cosmetic changes and even replacements which deviated  from designs that are initially approved by the National Historical Commission of the Philippines' Heraldry Division since 1950. These changes were often used concurrent to the ruling politicians or local political parties and some, if not most, were not submitted to the NHCP Heraldry Division for review and final approval of the president.
