A NIF (Número de Identificação Fiscal) document or card is a Portuguese taxpayer identification number required for various legal and financial activities in Portugal, including setting up utilities, opening a bank account, and importing goods.
You can obtain a NIF at a local Finance office (Serviço de Finanças) or through a Portuguese tax representative if you’re not in Portugal.
Important:
When submitting your NIF for an import, ensure the address matches your current residence. If it doesn’t, you can request an updated document at your local Finance office.
