How to cancel Santander by mail
Find your account details
Santander will look your account up from what the letter says, so check the account email, the last four digits of the linked bank account or card and the membership tier first.
Write your request
Postbye writes the letter in Portuguese from our Portuguese template, because Santander's address is in Portugal. It opens with the subject line “Assunto: Solicitação de Cancelamento – [your name]” and asks Santander to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Use certified mail for the 1100-063 Lisboa address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
File the receipt with the letter. A Santander charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Santander, with the envelope wording
Before you cancel Santander, check these
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
