What do you need a birth certificate for? Well, to prove we are who we say we are. We need it to be enrolled in school, citizenship, getting a passport, bank account and proving our age.
A birth certificate gives a child privileges and protection from exploitation.
It's something here but a third of the world's children do not have an official identity because they're not registered with the government at birth.
Most unregistered children live in Africa or Asia, but there are areas of the Pacific where it's been a challenge to keep any records on births.
The Solomon Islands is one of them.
Only 3,343 people are officially registered as being born in the Solomons (since the start of a UNICEF programme in 2011), although the population is over half a million.
In this report from the Solomons, Campbell Live’s Whena Owen explains how Unicef and a handful of Kiwis are giving thousands of children an official identity.
