How to Confirm Your Email on Portal das Finanças

Confirming your email address and phone number on the Portal das Finanças is one of those small admin jobs that is easy to skip and easy to regret. A confirmed contact lets the Portuguese tax authority send you alerts, and it is often a prerequisite before you can activate electronic notifications or recover your access. This guide walks through the process step by step.

Why a confirmed email matters

Once your email is confirmed, the Finanças can reach you for the things that actually carry deadlines. A verified email is useful for password recovery, for receiving electronic Notificações, and for IRS alerts. Without a confirmed contact you can miss filing deadlines and official letters, which is exactly the kind of silence that turns a minor issue into a penalty. If you do not yet have a NIF at all, you can get your Portuguese NIF online first and then come back to confirm your contact details.

Before you start

You will need to be able to log in to the Portal das Finanças. If you have not set a password yet, our guide on getting your Portal das Finanças password covers how to request and activate one. Keep your email inbox and your phone within reach, because the confirmation codes arrive in real time and can expire if you wait too long.

Step by step: confirming your contacts

Log in to the Portal das Finanças with your NIF and password.
Open your contact details. The quickest route is to use the site search and type "dados de contacto", or look for the section labelled Os Seus Dados de Contacto.
Enter your email address and your phone number in the relevant fields, then save the changes.
The Finanças sends a confirmation code to your email and a separate code by SMS to your phone.
Enter the code or codes where prompted to confirm each contact.

Once both are confirmed, the portal will show your email and phone as verified. That status is what other services check before letting you switch on electronic Notificações or reset access.

Common questions

What if the code does not arrive? Check your spam folder for the email, confirm the phone number you entered is correct, and request a new code if the first one has expired. What if my contact details are out of date? You can update them through the same Os Seus Dados de Contacto section and re-confirm.

This is also a good moment to review the rest of your tax profile while you are logged in. If a fiscal representative is still listed against your NIF and you no longer need one, see our guide on removing your fiscal representative. And if you are new to the Portuguese system and want the bigger picture, our explainer on what a NIF is and why you need one covers where this number fits into everything else.

Confirming your contacts takes only a few minutes, but it is the difference between hearing from the Finanças on time and finding out too late.
