How to cancel Diaria by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Diaria can only act on a request it can match to an account.
Set out the request
Diaria is based in Uruguay, so the letter goes out in Latin American Spanish, built from our Latin American Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send it by certified mail
Send it certified to Montevideo, Uruguay, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
Keep the tracking record with your copy of the letter. If Diaria bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Diaria cancellation letter goes
For a letter to Diaria, use Colonia 981, 11100 Montevideo, Uruguay.
Copy the postal code 11100 exactly: it is what routes the letter to Departamento de Montevideo, Uruguay.
Your details go in a block headed by Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado, and the opening line is “A quien corresponda:”.

Before you cancel Diaria, 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
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.
