NIF, the AIMA appointment inside the visa window, NISS, the health user number and a bank account in a sensible order, with the rules sources agree on and the ones we could not confirm.
In brief
As of 6 November 2026, the first 30 days in Portugal revolve around four numbers and one appointment: the tax number (NIF), the appointment at the immigration agency AIMA, the social security number (NISS) and the health user number (SNS). Sources report that a D7-type visa is valid for about 4 months with two entries, and that the AIMA appointment must fall inside that window, but waits are long: 6 to 12 months from consular filing to a card is a typical estimate. A bank usually asks for a passport, the NIF and a proof of address. We could not confirm the health-centre registration steps or the atestado de residência procedure.
What depends on your status
Portugal separates a visa holder from a person who already has a residence card. Sources describe the usual path of a non-EU newcomer in three steps: a national visa from the consulate, the AIMA appointment after arrival, and a residence card issued after the biometrics. The first permit is typically valid for 2 years and later renewals run for 3 years. Citizens of Russia, Belarus, Kazakhstan and Ukraine follow the same path as other third-country nationals. Which visa you hold decides everything else, and this article does not tell you which one to apply for.

Days 1 to 3: the minimum that cannot wait
- Put your passport, visa, the address where you are staying and the lease or title deed in one folder.
- Find the date of your AIMA appointment. Sources say it is often printed on the visa itself, and that it should fall inside the visa's validity of about 4 months (120 days, two entries). If it is not there, check the confirmation you received at the consulate.
- Get a NIF if you do not have one yet. Banks, landlords, utilities and the tax office all ask for it. See the next section.
- Get a local mobile number. We did not research the SIM registration rules, so ask the shop what it needs.
- Arrange private health cover for the first weeks. The state health service registration steps are below, and we did not find them confirmed.
- Ask the landlord for a signed lease and a utility bill in your name. A proof of address opens the bank, and later the health centre.
The NIF: the first number you need
The NIF is the Portuguese tax identification number. Several sources say it is free at a tax office (Finanças) and is usually issued on the spot if you bring your passport and, for residents, a proof of address.
For a non-EU applicant who lives abroad the picture is more complicated. Sources say such a person generally has to appoint a Portuguese fiscal representative. They disagree whether the electronic notifications channel on the Portal das Finanças can replace a representative: one guide says taxpayers outside the EU can subscribe to it and waive the representative, while the same guide notes that the official e-Portugal guide still lists the representative as a requirement. A tax-portal-based summary gives fines of about 75 to 7,500 euros for not appointing a required representative. Commercial pages say a NIF obtained through a representative takes roughly 7 to 10 working days and that online packages cost 50 to 150 euros. Treat those figures as secondary.
Once you become resident, remove the representative on the portal so they stop receiving your correspondence and charging fees. If you arrive with a residence visa, you may be able to apply in person with your Portuguese address. Confirm the current rule with the tax office.
For the NIF you may already have from a purchase, see the NIF, NIE and codice fiscale for buyers.
Week 1: address, NISS and the health user number
The social security number (NISS) is free. The official guide says you can apply online through the Social Security portal (the "Sou Cidadão" section) or at an office, and that foreigners who have a Portuguese address can apply for the NIF, the NISS and the national health user number (SNS) at the same time. Sources disagree about who is eligible: one says legal residence and a NIF, another says a job, a third says it depends on why you need the number. Check the current rules on gov.pt before you apply.
The health user number (número de utente) connects you to the national health service (SNS). We did not find the steps and documents for registering at a health centre, so ask the centre (centro de saúde) in your parish what it requires. Do not confuse the NISS with the user number: they are two separate numbers.
Until the health registration works, keep private cover. For choosing a policy and for what residence permits require, see health insurance after a move.
Weeks 2 to 4: the AIMA appointment and the bank
Sources report that a D7-type visa is valid about 4 months and that the AIMA appointment must fall inside that window. Waits are long, and some applicants have waited beyond the end of the visa. Estimates for the whole path from consular filing to a physical card range from 6 to 9 months to 6 to 12 months, and one source says the stage after biometrics alone can take 1 to 3 months. A fee of about 156 to 170 euros at the AIMA stage is quoted, but figures conflict. The first permit is typically valid for 2 years, with renewals for 3 years. None of this comes from an AIMA page.
What to do about it: - Do not leave the appointment until the last month of the visa. If the date was not given, contact AIMA and keep every confirmation. - Bring the documents the appointment letter lists. Pages that describe the AIMA stage list a passport, the visa, the NIF, a proof of address, proof of means and insurance, but check your letter. - Keep a copy of every receipt. It is the proof that your application is pending.
The bank is the other task of this period. Sources agree on the base documents: a passport, the NIF and a proof of address. They also report that the bank often wants a face-to-face meeting, a video call or notarised documents, and that some banks want a Portuguese address even from non-residents. Sources disagree about whether a foreign address is accepted. The residence certificate from the parish council (atestado de residência from the junta de freguesia) appears once as a proof of address; we did not find how to obtain it, so ask your parish.
For why some accounts are refused and what the alternatives are, see a resident bank account abroad, and for an owner's account, opening an account as an owner.
Driving, schools and the rest
We did not research the exchange of a driving licence, school enrolment and utilities for Portugal in this article. For licences, read driving licence abroad, and for the overall order of any move, the 30-day checklist. For tax, read tax residency when relocating. If you bought property and plan to let it, see buying where you holiday.
Typical mistakes of the first month
- Leaving the AIMA appointment until the visa is about to expire.
- Applying for the NIF through a paid package without checking whether you need a fiscal representative at all, or forgetting to remove the representative after you become resident.
- Treating the NISS and the health user number as one thing.
- Going to the bank before you have a NIF and a proof of address in your name.
- Assuming that a foreign address is accepted by every Portuguese bank.
- Relying on one forum post for fees. Figures conflict, and AIMA waits change.
- Losing receipts from the AIMA stage, which are your proof that a permit is pending.
One-page checklist
- Passport, visa, proof of address and lease or title deed in one folder.
- Date of the AIMA appointment found and written down.
- NIF obtained; fiscal representative question answered.
- Local mobile number.
- Private health cover for the gap period.
- NISS applied for, after checking eligibility on gov.pt.
- Health centre asked what it needs for the user number.
- Bank account application with passport, NIF and proof of address.
- AIMA documents prepared from the appointment letter; every receipt saved.
- A note of what remains open: driving licence, school, utilities.

FAQ
Do I need a NIF before I arrive? Many people do, because the bank, the landlord and the utilities ask for it. Non-EU applicants living abroad generally need a fiscal representative, though sources disagree about the alternatives. Confirm the current rule with the tax office.
How long is the visa valid and when is the AIMA appointment? Sources report about 4 months, with two entries, and the appointment must fall inside that window. The date is often printed on the visa. Waits are long, so contact AIMA early.
What is the difference between the NISS and the health user number? The NISS is the social security number. The user number connects you to the national health service. They are two separate numbers, though an official guide says that people with a Portuguese address can apply for several numbers at once.
Which documents does a Portuguese bank ask for? Sources agree on a passport, the NIF and a proof of address. Many also want a face-to-face check, and some a Portuguese address. Ask the bank before you go.
How long until I have a residence card? Estimates from commercial sources range from 6 to 12 months from consular filing to a card. They are not from AIMA, and waits change. Keep every receipt.
