The right of EU citizens to live and work in Spain is based on the European Union’s principle of free movement.
In Spain, the registration process is primarily governed by Royal Decree 240/2007, which implements Directive 2004/38/EC on the right of citizens of the European Union and their family members to move and reside freely within Member States.
Although the legal framework grants extensive rights to EU citizens, applicants must still comply with the registration requirements established under Spanish law when their stay exceeds three months.

Many people refer to the EU Registration Certificate as the Green NIE because it is issued on a small green paper document that includes the holder’s NIE number.
However, these terms are not technically the same. The NIE (Foreigner Identification Number) is simply your identification number in Spain, while the EU Registration Certificate confirms your legal residence as an EU citizen.
Despite the difference, the expression “Green NIE Spain” is widely used to refer to the registration certificate.
