What is NIE and why it matters for Erasmus+ interns
NIE stands for Número de Identificación de Extranjero. It is a unique identification number for foreign residents in Spain, used for tax, social security, and many day-to-day activities. For Erasmus+ interns, having an NIE is typically the prerequisite to legally working or interning, signing a contract, and setting up essential services.
- NIE is required to work, even if compensation is a stipend rather than a salary.
- You’ll need NIE to open a Spanish bank account and to sign rental contracts.
- NIE simplifies tax reporting and eligibility for social security contributions.
- NIE is not a visa; it is an identification number tied to your residency status in Spain.
Understanding NIE early helps you avoid delays that could derail administrative steps before your internship begins.
| Stage | What happens | Typical timing |
|---|---|---|
| Prepare documents | Collect passport, photos, EX-15, fee receipt, internship contract | A few days to a few weeks |
| Submit EX-15 and pay | Fill out EX-15; pay Modelo 790 receipt | Same day or within days |
| Appointment | Attend NIE appointment at Extranjería/Policía | Variable by city; weeks in advance |
| Receive NIE | NIE number assigned; you may get a provisional document | Same day to a few weeks |
| Optional TIE | Apply for residence card if staying long | Weeks after NIE |
- 1Identify your situation
Are you EU/EEA/Swiss, or non-EU? Do you plan to work, intern with a contract, or stay beyond a short visit? Your path to NIE may differ.
- 2Decide where to apply
If you are already in Spain, you can apply at a local police station or Oficina de Extranjería. If you are abroad, you may apply at a Spanish consulate.
- NIE
- Número de Identificación de Extranjero: your foreigner identification number in Spain.
- TIE
- Tarjeta de Identidad de Extranjero: the residence card issued after NIE for longer stays.
Who needs NIE for Erasmus+ internships in Spain?
In practice, any non-Spanish resident who will work, sign an internship contract, or access local services will likely need an NIE. EU/EEA/Swiss students generally experience a smoother path, but NIE remains a practical prerequisite for contracts, taxes, and banking. Non-EU students may face additional visa steps beyond the NIE.
- EU/EEA/Swiss students: NIE is usually required to work or intern and handle finances; expect straightforward steps with your passport and internship offer.
- Non-EU students: NIE is typically pursued alongside a visa or residency process; plan for extra documentation and processing time.
- Contract or internship offer: If you will sign a contract or receive a stipend, NIE is often necessary to formalize the agreement.
- Short stays: For very brief stays with no work or contract, NIE may still be useful for opening a local account or renting, depending on the landlord or employer.
If you’re unsure whether you need NIE for your specific situation, consult official guidance or a mobility advisor before you commit to documents.
| Term | Purpose | Who issues |
|---|---|---|
| NIE | Identification number for foreigners; tax and services | Spanish authorities |
| TIE | Residence card for long stays; proof of residency | Spanish government after NIE |
- 1Match your status to NIE needs
Identify whether you will work, study with a contract, or stay long enough to require local services.
- 2Check for additional visa steps
Non-EU students often require a work or student visa in addition to NIE.
When to apply for NIE
Timing matters. If you will be in Spain soon for your Erasmus+ internship, you can apply soon after you have either housing arrangements or a formal internship offer. If you are outside Spain, you can begin the NIE process from abroad via a Spanish consulate (or plan for a quick in-country appointment after arrival).
- Early planning pays off: start when you have a concrete internship offer or housing plan.
- If you arrive to Spain first, book the appointment as soon as possible after arrival.
- Applying from abroad can save time; check consulate options and required documents.
- Expect that appointment availability may vary seasonally; book early and monitor for cancellations.
The exact timeline depends on city and workload, but initiating early reduces risk of delays affecting your onboarding.
- 1Assess your arrival timeline
Map your internship start date and set a target NIE appointment date accordingly.
- 2Choose where to apply
If in Spain, plan for in-country appointment; if abroad, consider consulate processing.
Documents you’ll need for NIE
The exact documents can vary by city, but most NIE applications share a core packet. Collect well in advance and bring originals plus copies.
- Passport and a copy (including the photo page and the visa/entry stamp if applicable).
- Two recent passport photos that meet standard requirements.
- Completed EX-15 form (Solicitud de Número de Identidad de Extranjero).
- Proof of your internship offer or contract; include details of your stay and purpose.
- Proof of address in Spain (hotel, rental agreement, or correspondence).
- Modelo 790 código 012(s) receipt for the NIE application fee.
Having all documents ready reduces the risk of needing a new appointment or additional paperwork.
| Document | EU applicant | Non-EU applicant |
|---|---|---|
| Passport | Required | Required |
| EX-15 | Required | Required |
| Photos | Required | Required |
| Internship contract/offer | If available | If available |
| Proof of address in Spain | Helpful | Helpful |
- EX-15
- Official form used to apply for the NIE number.
- Modelo 790
- Receipt for the Extranjería/NIE processing fee (often 790-012). Include the code.
Where to apply and appointment tips
You can apply for NIE either in Spain (Extranjería/Policía) or from abroad (Spanish consulate). In Spain, book an appointment online via the local Policía or Extranjería portal; abroad, contact the nearest Spanish consulate. Bring all documents to the appointment.
- In Spain: go to the designated Extranjería office or police station with appointment.
- From abroad: use the Spanish consulate that handles NIE requests for your region.
- Book early; appointment slots can be scarce during peak travel seasons.

If you encounter delays, consider alternative appointment dates or neighboring offices; cancellations often appear online.
