The NIF (Número de Identificação Fiscal) is the essential Portuguese tax identification number required for almost every official activity in Portugal—from opening a bank account and signing a lease, to getting a job, accessing healthcare, or even shopping online. Here’s everything you need to know about obtaining your NIF as a foreigner, in 2025.
What is the NIF?
The NIF is the unique tax identification number issued by the Autoridade Tributária e Aduaneira (Portuguese Tax and Customs Authority).
Why do you need an NIF?
You cannot work, study, rent a home, open a bank account, sign up for utilities, or conduct most financial or legal transactions without this number.
