Nationality in Guinea is governed by the Code civil of 2019. The reforms of 2019 eliminated discrimination based on sex in the transmission of Guinean nationality to children and spouses. The Code also provides for automatic attribution of Guinean nationality to a child born in Guinea of one parent also born there, and to a child born in Guinea of parents who are unknown, stateless or of unknown nationality. A newborn child found in Guinea is presumed to be Guinean.

In 2015, Guinea adopted a national action plan for the eradication of statelessness, supplemented by a decree adopted in 2017 establishing the institutions to implement the plan.

The UN Committee on the Rights of the Child expressed concern in 2013 that only one third of births are registered, and remained concerned in 2019, despite efforts at reform.
