How to cancel Sumup by mail
Note your account details
You will need the account email, the last four digits of the linked bank account or card and the membership tier. Use exactly the details Sumup holds, so the request can be matched to your account.
Set out the request
Postbye writes the letter in Italian from our Italian template, because Sumup's address is in Italy. It opens with the subject line “Oggetto: Richiesta di cancellazione – [your name]” and asks Sumup to end the subscription, stop all further charges and confirm in writing.
Post the letter
Send it certified to Milano, Italy, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any Sumup charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Sumup cancellation letter goes
Sumup takes its post at Via Tortona 37, 20144 Milano, Italy, which is where a cancellation letter belongs.
Postal code 20144 places the address in Lombardia, Italy.
Inside, the salutation reads “A chi di competenza,”, followed by your details under Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata.

Before you cancel Sumup, 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.
