In the entire world, Zainuddin (Zainuddin , Зайнуддин , Заинуддин ) is a common predominantly masculine, but scarcely female first name. The forename Zainuddin is characteristic of South-eastern Asia, particularly Brunei, where it is quite a rare masculine name, Indonesia, where it is quite a rare principally boy's, but very infrequently female name, and Malaysia, where it is quite a rare masculine name. Not in comparison with a country's population, it most frequently occurs in Indonesia, India, and Malaysia. Likewise, Zainuddin is the last name as well as the forename.
