Portugal Bureaucracy’s Triple Crown Is Ours

Portugal requires three identification numbers for foreign citizens to live within its borders. After a year of application filing and waiting (and filing and waiting some more!), Ted and I each earned the last of our three ID numbers this week.

We feel as if that old bull in the labyrinth has finally been slain.

The number is called the NISS (Número de Identificação da Segurança Social), the Portuguese social security number. It is mandatory for working, paying taxes, accessing healthcare and other social benefits in Portugal.

Though these two happy retirees don’t intend to work in Portugal or earn income here–in fact, our non-lucrative category of visa forbids it–we need the NISS number to obtain European health cards, which entitle us to national healthcare coverage wherever we travel in the European Union.

And travel we plan to do. So we went for the NISS.

Our NISS numbers join the other two numbers in our triumvirate:

• The NIF. The Número de Identificação Fiscal is an individual’s tax identification number. One needs it to open a bank account, rent property and sign up for utilities. It was the first number we scored when we started the immigration process last year.
• The SNS. The Serviço Nacional de Saúde number entitles an individual to use the public healthcare system in Portugal. Each of us got an SNS number fairly early in our immigration process, but the numbers were held in provisional status until we received our two-year residency permits in April this year.

Of the three, the NISS number was the toughest to obtain.

We had to have our residency permits to apply for the NISS, and obtaining the permits required a January trip from our home in Porto to a mobbed Lisbon immigration office, where we waited for three hours with hundreds of other wannabees (and an attorney from the firm we hired in 2025 to help us through the relocation process) to submit our application paperwork. Once back home in Porto, we waited 90 days before we held those blessed, wallet-sized residency trophies in our hands.

In April, with the residency hurdle cleared, we first had to visit a local government services office, called a citizen store, to apply for another bowl of acronym soup, the CMD, (Chave Móvel Digital), a password that is the official digital authentication system used by the Portuguese government. The CMD enables access to essential government services online, like family support programs, business license application, passport renewal … and social security benefits.

Once we got the CMDs, we had to make an appointment for a second visit to the citizen store to apply for the NISS. After that appointment came several weeks of online inquiries to check the status of our NISS applications, each time using our CMDs to gain access to the gov.pt system.

The online app reported that the NISS numbers had been granted, though the button to download them led to a screen that told us technical problems prevented the download.

At this stage of the game, our neighbors from Atlanta, with a planned trip to attend a wedding in Italy in a few weeks, enlisted our relocation attorney’s help and got their numbers so they can have their European health cards before flying off to Italy. We tried that route, but were able to get the numbers on our own this past Friday. The download button finally worked … without the attorney’s intervention.

Whew! The final puzzle piece was in place at last!

All this is to say that becoming a legit foreign expat in Portugal is not an easy process.

Seasoned expats who have lived in Porto longer than we have offer wise counsel to take the bureaucratic delays and annoyances with a grain of salt. Wishing Portugal had a simpler system with only one identification number instead of three is a fruitless exercise, they say, and we agree. Best to accept it for what it is and move on … and enjoy the little victories along the way.

And the pleasures of life here. The delicious fresh asparagus at the local markets. The Sunday morning concerts. The murals and artistic tile work everywhere around us. The incredibly easy mobile apps for filling prescriptions and securing doctors’ appointments–light-years ahead of the systems available in the States.

Then there is the kindness of the local people, who don’t seem at all harried by whatever government red tape they encounter on a typical day.

I’d say we made more than a fair trade.

And we’re ready to tackle the next challenge: applying for our European health cards.

Please wish us luck!
