The office of the City Civil Registrar in Zamboanga City was created under Ordinance No. 188, series of 1984. Prior to this, the Secretary to the Mayor served as Ex-Officio Civil Registrar.
The Local Government Code of the Philippines of 1991 (RA7160) strengthened the existence of the office and provides that in highly urbanized cities, like Zamboanga City, civil registration shall be performed by the City Civil Registrar, whose office is listed among the mandatory offices of the local government unit.
The registration of civil registry documents of births, marriages, deaths and vital events affecting the civil status of people in the local level is being done by the City Civil Registrar.
