Understanding the Portuguese NIF Number: What It Is and Why You Need One

If you’re planning to live, invest, or do business in Portugal, you’ll need a NIF number—short for Número de Identificação Fiscal (Tax Identification Number). This 9-digit number is a unique personal identifier used in almost all legal and financial transactions.

Whether you’re buying property, signing a lease, or opening a bank account, having a NIF is essential.

How to Get a NIF Number

You can obtain a NIF at any Portuguese tax office (Serviço de Finanças) or designated service location. The number is issued on the spot and free of charge.

Additional fees may apply if you request an official card or need a fiscal representative.

Do You Need a Fiscal Representative?

If you are not a resident of Portugal or another EU country, you will need a tax representative.

This individual or entity will handle tax-related communication and ensure compliance with Portuguese tax law. Eligible representatives include:

  • A friend or acquaintance residing in Portugal
  • A professional service or company

Nationality does not matter—the person must simply reside in Portugal and accept the responsibility.

Can You Get a NIF Without Being in Portugal?

Yes. You can apply remotely by providing the following documents:

  • A copy of your passport
  • Proof of address (e.g., utility bill, bank statement)
  • A power of attorney authorizing someone to apply on your behalf
