Contrary to popular belief, obtaining an NIF is quick and easy, even for non-EU/EFTA citizens, with the possibility of acquiring it online for less than €100 and in less than a week. In this comprehensive guide, I explain everything you need to know about obtaining your Portuguese NIF in 2025, online or in person, without hassle or excessive costs.

What is a NIF?

The NIF, short for "Número de Identificação Fiscal", is a unique nine-digit personal identification number used in Portugal. Each resident is allocated a NIF, which remains valid indefinitely. Whether you need to open a bank account, sign an employment contract, or simply make purchases, the NIF will accompany you in almost all financial and administrative transactions in Portugal.

Why is the NIF essential?

The NIF is essential for anyone planning to live in Portugal. Here are some of the situations in which having a NIF is compulsory:

Applying for a Portuguese visa for non-EU/EFTA citizens;
Opening a Portuguese bank account;
Buying or renting a property in Portugal;
Subscribing to service contracts (internet, telephone);
Receiving an inheritance in Portugal;
And many other everyday circumstances.

As well as many other procedures. In short, the Portuguese NIF is simply essential for access to basic services such as accommodation. It's not for nothing that the NIF is cited as the first and most important step to take before moving to Portugal.

How do I obtain a NIF?

For citizens outside the EU/EFTA

If you are a citizen from outside the European Union, the European Economic Area or Switzerland, here's how you can obtain your Portuguese NIF:

Via an online company or law firm: This is the easiest and quickest way to obtain your NIF, especially if you are abroad. Several companies offer this online service, guaranteeing that you will obtain your NIF in less than a week at a cost of less than €100. Make sure you choose a reputable provider by checking online reviews.
In person: You can also obtain your NIF directly in Portugal by visiting a Finance office or Loja do Cidadão. Note that as a non-EU/EFTA resident, you will need a tax representative in Portugal, which may make this option more difficult if you do not already have contacts in the country.

For EU/EFTA citizen

If you are a citizen of an EU, EFTA or Swiss member state, you can obtain an NIF in the same way:

Via an online company or law firm: Once again, this is the quickest and easiest way to obtain your NIF from your current country. Several companies offer this online service, guaranteeing to obtain your NIF in less than a week at a cost of less than €100. Make sure you choose a reputable provider by checking online reviews.
In person: The most direct way to obtain a NIF is to go to a Finance office or Loja do Cidadão in Portugal. As an EU/EFTA citizen, you do not need a tax representative and the service is free. Bring your passport or national identity card and proof of address.

Documents required to obtain a NIF

To apply for a NIF, you will need :

Passport or National Identity Card: For all applicants, a valid identity document is required. Only EU citizens can apply for a NIF with an identity card.
Proof of Residence: An official document such as a utility bill, bank statement or driving licence, showing your current address.

If the application concerns a minor child, then the birth certificate will be required, and one of the parents will be the legal representative.

Obtaining a NIF in person

For those who choose to apply for their NIF in person in Portugal, here are a few tips:

Locate the nearest office: Use Google Maps to find a Finanças office or Loja do Cidadão near you.
Arrive early: Offices can be very busy, especially in big cities like Lisbon or Porto. Arriving early can help you avoid long waits.
Minor fees: For non-EU/EFTA residents, applying for an NIF may involve a minor administrative fee.

If you are already in Portugal then you will need to present the following documents:

Passport or identity card for EU citizens
Proof of address outside Portugal

Issuing the NIF is free and instantaneous when the request is made directly at a Portuguese tax office.

Be careful, however, as some offices do not accept people without an appointment made in advance, and queues are, as in all Portuguese public services, very long. What's more, no member of staff is required to speak any language other than Portuguese, so you may find it difficult to understand and make yourself understood. In the end, it is advisable to apply for your NIF online, before coming to Portugal. This saves time and money.
