Renewing the passport or obtaining it are essential steps before traveling to a foreign country.
The passport is also required for children, including those under 14 years of age.

It should be remembered that, in Spain, getting a DNI is not mandatory until the age of 14, hence the confusion that usually exists with the passport.
