How to cancel Kirvano by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Kirvano names the right account the first time.
Write your request
Postbye drafts the request in Brazilian Portuguese, the language of Brazil, with “Assunto: Solicitação de cancelamento – [your name]” as the subject line. It asks Kirvano to close the subscription, stop billing and confirm in writing.
Post the letter
Mail the letter by certified mail to the São Paulo address in the next section, and keep the tracking number.
File the delivery record
File the receipt with the letter. A Kirvano 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.
Where your Kirvano cancellation letter goes
For a letter to Kirvano, use Alameda Rio Negro 503, 06454000 São Paulo, Brazil.
The postcode 06454000 belongs to São Paulo, Brazil, so this is where the envelope is delivered.
The database also lists Rua Pais Leme 215, 05424150 São Paulo, Brazil for Kirvano. Use the first address above unless your agreement names this one.
The letter greets the reader with “A quem possa interessar,”; your own details sit under the labels Titular da conta, Endereço de cobrança cadastrado and E-mail cadastrado.

Before you cancel Kirvano, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
