According to the search results, the age requirement for voting in the Sangguniang Kabataan (SK) elections is between 18 to 30 years old. However, it is worth noting that minors as young as 15 years old may now register to vote for the SK elections. On the other hand, for the barangay elections, the age requirement is at least 18 years old. It is important to keep in mind that voter applicants must be residents of the Philippines for at least one year from the elections and at least six months resident at the place they will be registering and voting. They must also present a valid ID and birth certificate to validate their identity and determine their age.
