How to cancel 12min by mail
Start with your account details
12min will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write your request
Postbye writes the letter in Brazilian Portuguese from our Brazilian Portuguese template, because 12min's address is in Brazil. It opens with the subject line “Assunto: Solicitação de cancelamento – [your name]” and asks 12min to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Mail the letter by certified mail to the Belo Horizonte address in the next section, and keep the tracking number.
Save the tracking record
The receipt dates your request. Look at your next statement for any 12min charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 12min cancellation letter goes
12min lists Avenida Assis Chateaubriand 499, 30150101 Belo Horizonte, Brazil as its mailing address.
The envelope is going to Belo Horizonte in Minas Gerais, Brazil, so the postcode 30150101 must be on the front.
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.
Prefer to write it yourself? Use our letter template
Before you cancel 12min, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
