If you’re considering buying property, relocating, or simply spending extended time in Spain, two acronyms will quickly appear on your paperwork: NIE and TIE. While they sound similar, they serve very different purposes. Understanding the distinction is essential for expats planning a move to the Costa del Sol—especially in popular areas like Mijas Costa, where a large international community calls home.
What is an NIE?
The NIE (Número de Identificación de Extranjero) is a foreigner’s identification number. Think of it as your personal tax ID in Spain. It is unique to you and stays with you for life, even if you leave Spain and later return.
You will need an NIE for:
- Buying property in Spain
- Opening a bank account
- Starting a job or business
- Paying taxes
- Utility contracts (water, electricity, internet)
- Any official financial transaction
The NIE is not a residency card. It’s purely an identification number for legal and tax purposes.
What is a TIE?
The TIE (Tarjeta de Identidad de Extranjero) is a residency card. It is a physical card (similar in size to a driving licence) that contains your NIE number, photo, fingerprint, and residency details.
The TIE proves your legal right to reside in Spain. This document is especially relevant for:
- UK nationals post-Brexit (now required to hold a TIE to reside in Spain legally)
- Non-EU nationals applying for residency permits
- Expats staying in Spain for longer than 90 days
In short: the NIE identifies you for transactions, while the TIE proves your residency status.
Key Differences Between NIE and TIE
| Feature | NIE | TIE |
|---|---|---|
| What it is | Identification number | Residency card |
| Format | Paper certificate (number only) | Plastic card with photo & chip |
| Purpose | Legal/tax transactions | Proof of legal residency |
| Who needs it | Anyone dealing with official matters in Spain | Non-EU citizens & UK nationals post-Brexit |
| Validity | Permanent (same number for life) | Linked to your residency permit (must be renewed) |
Which One Do You Need?
- If you are buying a holiday home in Mijas Costa, you will only need an NIE.
- If you are relocating permanently, especially as a non-EU national, you will need a TIE.
- Many expats start with just an NIE for property purchase, and later apply for residency (TIE) when moving full-time.
Why This Matters for Expats in Mijas Costa
Mijas Costa is one of the most attractive areas for expats on the Costa del Sol, thanks to its stunning beaches, golf courses, international schools, and close proximity to Málaga airport.

Understanding the difference between an NIE and a TIE helps avoid confusion, delays, and unnecessary stress during your Spanish journey.
