During Rotary Year 1977-1978, District 380 which then comprises all clubs in Luzon was first divided. Newly created District 3820 comprises half of Metro Manila (south of Pasig River), Southern Tagalog, Bicol Region and the Islands of Mindoro, Palawan and Marinduque. It was this year when the District chartered the District Rotaract Organization.

By the Rotary Year 1985-1986, District 3820 was further divided into two (2): District 3810 and District 3820. District 3810 comprises half of Metro Manila (south of Pasig River), Cavite, Palawan and Mindoro Island.

It was in Rotary Year 1999-2000 when the re-districting of District 3810, one of the largest Rotary Districts in the world with over a hundred Rotary Clubs took place. The district gave birth to District 3830 which covers the area of Makati, Las Piñas, Parañaque, Taguig, Pateros, Palawan and Oriental Mindoro. District 3810 was left with Manila, Pasay, Cavite and Occidental Mindoro.
