What is the CRUE in Spain?
The CRUE (Certificado de Registro de Ciudadano de la Unión) is an official registration certificate issued to EU, EEA, and Swiss nationals residing in Spain for more than three months. It confirms your legal right of residence under EU free movement rules and is sometimes called the EU residence certificate Spain or the "green NIE certificate."
The CRUE includes your name and nationality, your Spanish NIE (Número de Identificación de Extranjero), and your registration date. It is issued on paper, not as a plastic residence card.
Who Needs to Register for the CRUE?
Any EU, EEA, or Swiss citizen staying in Spain longer than 90 days is legally required to apply for EU citizen registration. This includes:
- Employees working for Spanish companies
- Self-employed professionals (autónomos)
- Individuals with sufficient financial means and private health insurance
- Students enrolled in recognised institutions
Failure to register may cause administrative issues in future immigration or residency procedures. Many EU citizens mistakenly believe registration is optional — it is not.
