How to get a Portuguese NIF without a local address

What a NIF is — and why everything asks for it

The NIF (Número de Identificação Fiscal) is a nine-digit personal tax number issued by the Portuguese tax authority (Autoridade Tributária e Aduaneira — you'll see it shortened to "AT", and the offices called Finanças). Portugal uses it the way some countries use a social-security or national-insurance number: as the identifier that ties you to contracts and money.

That's why it shows up everywhere. Signing a lease, opening a bank account, setting up electricity or internet, getting paid a salary, even some larger shop purchases — the form has a NIF field, and things stall without it. For most movers it's the single most useful piece of paperwork to sort early.

The loop — and the fact that breaks it

The exit is simpler than it looks: the address on your NIF application doesn't have to be Portuguese. When you first request a NIF, you can generally register with your current address abroad — the one where you actually live. The tax authority's records simply show you at a foreign address until you have a Portuguese one, at which point you update it.

In other words, the loop is an illusion of ordering. The NIF comes first, attached to your old address; the lease comes second; the address update comes third. Movers who don't know this often wait until after arrival and lose weeks — the ones who sort the NIF before flying walk into apartment viewings already holding the number everyone asks for.

The routes to a NIF

There are three routes people commonly use. Which ones are open to you depends on where you're resident and whether you're an EU/EEA citizen — the official pages linked below set out exactly which applies.

1. In person, in Portugal

Walk into a tax office (Serviço de Finanças) or a citizen shop (Loja do Cidadão) with your identity document and evidence of your current address. In busy cities, check whether you need to book ahead — queues and appointment systems vary by office.

2. Through a fiscal representative

Depending on where you're resident, you may be asked to appoint a fiscal representative — a person or company in Portugal who acts as your point of contact with the tax authority. Whether this is required for you (and whether alternatives such as electronic notifications apply instead) has changed over recent years, so treat any blog's summary — including ours — as a prompt to check the current official rule, not as the rule itself.

3. Remotely, before you move

There are official channels for requesting a NIF from abroad, and a market of private services that will handle the process for a fee. If you use a paid service, know what you're paying for: convenience. The underlying request is the same, and the official route is the cheap one — check current costs on the official pages rather than taking a service's word for it.

What to have ready

• Your passport or national ID (EU/EEA citizens can typically use their ID card).
• Evidence of your current address — the address where you live now, which can be outside Portugal. Acceptable documents vary; the official pages list them.
• If a fiscal representative applies to your case: their details and their agreement to act for you.

Once you have the number, keep the document you're given safe, and when you eventually sign a Portuguese lease, update your address with the tax authority so their records — and everything that flows from them — point at the right place.
