If you’re moving to Spain, buying property, working, starting a business, or even just opening a bank account, you’ll quickly encounter a confusing mix of Spanish acronyms: NIE, NIF, TIE and the Green Card.
Many people assume these are interchangeable — but they are not. Each serves a different legal purpose, and misunderstanding them can cause serious delays, rejected applications, or even legal issues.
This guide clearly explains what each document is, who needs it, how they relate to each other, and which one you actually need.

Quick Overview: NIE vs NIF vs TIE vs Green Card
| Document | What It Is | Who It’s For | Is It Residency? |
|---|---|---|---|
| NIE | Foreigner Identification Number | All non-Spanish nationals | ❌ No |
| NIF | Tax Identification Number | Spaniards & foreigners | ❌ No |
| TIE | Physical residency card | Non-EU residents | ✅ Yes |
| Green Card | EU residency certificate | EU citizens | ✅ Yes |
What Is a NIE Number?
A NIE (Número de Identidad de Extranjero) is a unique identification number assigned to foreigners in Spain.
Key Facts About the NIE
- It is a number, not a card
- It never expires
- It is required for almost all legal and financial actions
- It does not grant residency
What Do You Need a NIE For?
You need a NIE to:
- Buy or sell property in Spain
- Open a Spanish bank account
- Work or register as self-employed
- Pay taxes
- Register a vehicle
- Apply for residency
- Inherit assets
- Sign contracts (utilities, phone, internet)
Important:
Having a NIE does NOT mean you are a resident of Spain.
What Is a NIF in Spain?
A NIF (Número de Identificación Fiscal) is a tax identification number.
Who Has a NIF?
- Spanish citizens: Their NIF is their DNI number
- Foreigners: Their NIE becomes their NIF for tax purposes
👉 This is where confusion often starts.
NIE vs NIF – Are They the Same?
- The number itself is identical
- The context is different
| Context | Name Used |
|---|---|
| General identification | NIE |
| Tax matters | NIF |
If you pay tax, submit forms to Hacienda, or invoice clients, your NIE functions as your NIF.
What Is a TIE Card?
A TIE (Tarjeta de Identidad de Extranjero) is a physical residency card issued to non-EU nationals living in Spain.
Key Features of the TIE
- Plastic ID card with photo and fingerprint
- Proves legal residency
- Includes your NIE number
- Has an expiry date
- Must be renewed when it expires
Who Needs a TIE?
- UK nationals post-Brexit
- US, Canadian, Australian citizens
- Any non-EU citizen living in Spain long-term
Important Clarification
The TIE is not your NIE.
The NIE is the number printed on the TIE card.
What Is the Spanish Green Card?
The Green Card is the informal name for the EU Certificate of Registration.
Who Gets a Green Card?
- EU citizens (including Irish citizens)
- EEA nationals
- Swiss nationals
What Does It Look Like?
- Green A4 paper or green credit-card format (depending on province)
- No photo
- Includes your NIE number
- Issued once and never expires (though details must stay up to date)
What Does It Prove?
- Legal EU residency in Spain
- Right to live and work in Spain
NIE vs TIE vs Green Card: The Real Difference
Think of It Like This:
- NIE → Your ID number in Spain
- NIF → Your tax ID (same number as NIE)
- TIE → Residency card for non-EU citizens
- Green Card → Residency certificate for EU citizens
You cannot choose between them — your nationality decides which residency document applies.
Common Mistakes People Make
❌ “I have a NIE, so I’m a resident”
False. A NIE alone does not grant residency.
❌ “My TIE is my NIE”
Incorrect. Your NIE exists independently of the card.
❌ “EU citizens get a TIE”
No. EU citizens receive a Green Card, not a TIE.
❌ “I don’t need a NIE if I’m not a resident”
Wrong. Many non-residents still need a NIE.
Do You Always Need a NIE First?
Yes.
Both the TIE and Green Card are issued using your NIE number.
No NIE = no residency document.
Which One Do You Need?
You need a NIE if:
- You are a foreigner with any legal or financial activity in Spain
You need a Green Card if:
- You are an EU citizen living in Spain over 90 days
You need a TIE if:
- You are a non-EU citizen living in Spain
You use a NIF when:
- Paying tax or dealing with Hacienda
Can You Have All of Them?
Not exactly:
- Everyone has either a TIE or a Green Card
- Everyone has a NIE
- Everyone dealing with tax has a NIF
- Spaniards have DNI instead

No. It is an identification number only.

No. The number is permanent.

Can EU citizens get a TIE?

Can I work in Spain with just a NIE?
Only if you also have the correct residency or work authorisation.
Final Summary
If you remember just one thing:
The NIE is your number.
The TIE or Green Card is your residency status.
The NIF is how the tax office sees you.
Understanding the difference will save you time, money, and stress — and help ensure you stay fully legal in Spain.

You can apply for a tie at http://www.tiecardspain.com or you can apply for a green residency card. You have the best of both worlds.
