Obtaining NIF and NISS in Portugal

Moving to Portugal or doing business here opens up many opportunities, but also requires resolving a number of administrative issues. Two of the most important are obtaining an NIF (Número de Identificação Fiscal) and an NISS (Número de Identificação da Segurança Social). Portugal Dom company will help you quickly and effortlessly process these necessary documents.

NIF / NISS

What are NIF and NISS?

  • NIF (Número de Identificação Fiscal):

    • This is your individual tax number in Portugal.
    • It is necessary for any financial transactions: opening a bank account, buying real estate, concluding contracts, etc.
    • It is impossible to live a full life in Portugal without an NIF.

    NISS (Número de Identificação da Segurança Social):

    • This is your social security number.
    • It is necessary for employment, receiving medical care, and social benefits.
    • NISS guarantees you access to the Portuguese social security system.

“Thanks to Portugal Dom my life has been transformed!
When I arrived in Portugal in 2020, I faced difficulties. The usual story: I went to a lawyer, paid money, but the problem remained unsolved and the lawyer disappeared.

It was a happy accident that I turned to Portugal Dom. Here I was not only helped with documents at affordable prices, but also helped me to find a job and buy a car. Recently I received my long-awaited residence permit, I am traveling around Europe and I am immensely grateful to Portugal Dom for a new stage in my life!

“Good afternoon everyone! Repeatedly applied to many emigration services in Portugal, to help with the paperwork and except for deception and a request to give them money did not get anything.

And now I turned to “PORTUGAL DOM” – consultations, help in translations and promotion of documents, human attitude to people and clients. I have never seen such a wonderful service in Lisbon. THANK YOU to Irina Panfilova, Angelica, Steph in helping me with the processing of my documents.

Sergey

from Ukraine

“I have been in Portugal for more than 30 years and have had Portuguese citizenship for a long time. I regularly turn to Portugal Dom for help with power of attorney, consulate entries and real estate issues in Russia.

They provide professional assistance in all matters related to documents and legal procedures.


I am very happy to have found Irina and her team.“

LUDMILA

from Russia

“I couldn’t order an invitation to the consulate for a long time because everything was always busy.

I contacted Irina and everything was done in a week. I came to the consulate with ready documents and it helped a lot at the reception! Thank you very much!“

IRINA

from Ukraine

“Thank you to Irina and the Portugal Dom team! Prepared documents for my daughter’s citizenship. Everything in time and with a responsible approach. I recommend!

MARIA

from Russia

“For a long time I could not get a certificate of no criminal record from Azerbaijan to apply for Portuguese citizenship.

Irina not only found a unique solution for my criminal record certificate (we obtained this certificate through the Azerbaijani Consulate in Morocco), but also provided support at every stage of the process. Now, with all the documents in hand, I live and work in France.

Portugal Dom sincerely strives to help people with full dedication.

ILYA

citizen of Ukraine, born in Azerbaijan

Thank you so much Portugal Dom and personally Irina for their incredible help!

For more than 20 years I lived illegally in Portugal without having a residence permit and not knowing how to start. In 2018, I contacted Portugal Dom where Irina not only helped me with all the paperwork, opening a sole proprietorship, obtaining a residence permit, but also sorted out the paperwork for my mother.

I now regularly turn to Portugal Dom for tax and financial advice. I can’t imagine how I would have coped without their help! ”

ALEXANDER

from Kiev

“Without Irina and Portugal Dom I would not have been able to realize my dream of living with my family in Portugal. Thanks to Irina’s help I got Portuguese citizenship myself.

After some time I got married in Russia, but I could not bring my wife to Portugal for permanent residence. Irina helped with the visa and other documents necessary for my wife to move. Now she has a residence permit, now she is waiting for citizenship. Thank you for your invaluable help!

VICTOR

from Russia

“Irina and her team saved me from numerous difficulties I faced after coming to Portugal. I came to Portugal in 2014 to get married.

After a failed marriage and stories of people extorting money from me, I was confused, literally didn’t know what to do. I didn’t know anyone in Portugal, much less someone who spoke Portuguese.
I believe that only a miracle helped me to meet Irina. I went to her for help. She helped with the divorce process, helped me find a place to live, and helped me go all the way to citizenship. Portugal Dom’s support changed my life.
