Before the visa comes the paperwork: almost every move to Portugal starts with a tax number and a bank account. Test what you know about the first administrative steps.
The NIF (Número de Identificação Fiscal) is your Portuguese tax number. It is used for almost every official and financial transaction in Portugal.

A NIF and a Portuguese bank account are needed when applying for a residence visa, and the NIF is also required to open a bank account or sign a lease.

You do not need to travel to Portugal to get a NIF. A Portuguese lawyer or representative can obtain it for you remotely.

Portuguese legal professionals can authenticate your documents during a video call, allowing a bank account to be opened remotely.
The NISS (Número de Identificação de Segurança Social) is your social security number, needed to work, make contributions and access social benefits in Portugal.
The número de utente registers you with the SNS, Portugal's national health service, so you can use public health centres and hospitals.
Foreigners with a Portuguese address can request their NIF, NISS and número de utente together. This is a convenience; each can also be obtained separately.
