How to cancel 99Pay by mail
Gather your account details
Before writing, collect the account email, the last four digits of the linked bank account or card and the membership tier. 99Pay can only act on a request it can match to an account.
Put the request in writing
99Pay is based in Brazil, so the letter goes out in Brazilian Portuguese, built from our Brazilian Portuguese template. Subject line: “Assunto: Solicitação de cancelamento – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail the letter with a receipt
Use certified mail for the 01310200 São Paulo address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any 99Pay charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 99Pay cancellation letter goes
99Pay lists Avenida Paulista 1912, 01310200 São Paulo, Brazil as its mailing address.
The postcode 01310200 belongs to São Paulo, Brazil, so this is where the envelope is delivered.
The letter is addressed “A quem possa interessar,” and its details block uses the labels Titular da conta, Endereço de cobrança cadastrado and E-mail cadastrado.

Before you cancel 99Pay, 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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
