If you are coming to Portugal to study — on Erasmus, a full degree, or an exchange — a NIF (número de identificação fiscal) quickly becomes one of the most useful things you can have. It is the nine-digit Portuguese tax identification number, and although your university enrolment itself may not always require it, almost everything around student life does: renting a room, opening a bank account, getting a phone contract, and sometimes receiving a scholarship or grant.
What a student actually needs a NIF for
- Accommodation — landlords and student residences ask for a NIF before a lease is signed
- A bank account — a Portuguese bank account cannot be opened without one
- A phone or internet contract — registered against your NIF
- Scholarships, grants and part-time work — each is a fiscal event tied to your number
EU and non-EU students
Any student can hold a NIF, resident or not. Whether you are an EU or EEA student or a non-EU student — for example from Brazil, the UK, the US or India — you can request a NIF without appointing a representative. A fiscal representative in Portugal may become necessary once you establish a tax relationship with Portugal (for example, an employment contract or self-employed work), when the Tax Authority can require the appointment within 15 days. With NIF Express the price of €49.99 already includes your first year of representation, so there is nothing extra to arrange.
Erasmus and exchange students
An exchange student does not need a NIF to enrol, but landlords, banks and phone shops ask for one in the first week. It can be requested remotely before you arrive, typically in 5–14 business days, so it is wise to apply a few weeks before you travel.
For an adult, two documents are usually enough: a copy of your valid passport or national ID and a proof of address in your home country issued within the last 3 months. Our documents checklist shows the full list.
Whether you will ever need a fiscal representative depends on whether you establish a tax relationship in Portugal; see who needs a fiscal representative. NIF Express includes the first year of fiscal representation in the €49.99 price.
Get it before you arrive
The smartest move is to have your NIF ready before term starts. Student housing in university cities moves fast, and not having a NIF is a common reason a room slips away. Because the number can be obtained entirely remotely, you can apply from home and arrive ready to sign a lease and open a bank account in your first week rather than your second month.
How students get one
The process is fully online — no consulate appointment, no tax-office queue. With NIF Express your number is typically ready in 5–14 working days, with the power of attorney signed by a lawyer registered with the Portuguese Bar Association, and it stays valid throughout your studies and beyond — the NIF is permanent and never expires.

Frequently asked questions
Do Erasmus or international students need a NIF?
For enrolment it is not always required, but for housing, a bank account, a phone contract and scholarships it effectively is. Most students get one soon after (or before) arriving.
Can I get a NIF as a student before I arrive in Portugal?
Yes. It can be obtained entirely remotely, so you can apply from home and have it ready to rent and open a bank account in your first week.
I am a non-EU student — do I need a fiscal representative?
Not to request the NIF. A fiscal representative may be needed once you establish a tax relationship in Portugal, and the Tax Authority then allows 15 days to appoint one. With NIF Express the €49.99 price includes the first year of representation.
Does the NIF expire when my course ends?
No. The NIF is permanent and never expires, so you keep the same number if you stay, work, or return to Portugal later.
How long does it take and what does it cost?
Typically 5–14 working days with NIF Express, at €49.99 including the first year of fiscal representation.
Do Erasmus students need a NIF in Portugal?
Not to enrol, but a NIF is requested for most practical things: a rental contract, a Portuguese bank account, a mobile plan and utilities. Many students get it before arriving.
Can I get a NIF before I arrive for my exchange?
Yes. The application is made remotely, with document upload and a power of attorney, so you do not need to travel or attend an appointment. It is typically issued in 5–14 business days.
Does an Erasmus student need a fiscal representative?
Not to request the NIF. The obligation only arises if you establish a tax relationship in Portugal, and the Tax Authority can then require a representative within 15 days. NIF Express includes the first year of fiscal representation in the €49.99 price.
