How to cancel Acunsa by mail
Collect the details you need
Before writing, collect the member or policy number, the full name of the policyholder and the date you want the plan to end. Acunsa can only act on a request it can match to an account.
Prepare the letter
The request is prepared in Spanish (template es), under the subject line “Asunto: Solicitud de cancelación – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Mail the letter by certified mail to the Pamplona address in the next section, and keep the tracking number.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Acunsa was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Acunsa cancellation letter goes
Acunsa lists Avenida de Pío XII 57, 31008 Pamplona, Spain as its mailing address.
The envelope is going to Pamplona in Navarra, Spain, so the postcode 31008 must be on the front.
The letter greets the reader with “A quien corresponda,”; your own details sit under the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.
Prefer to write it yourself? Use our letter template
Before you cancel Acunsa, check these
- Claims for care received before the end date can still be processed. Ask how to submit them after you cancel.
- Do not cancel until your next plan is active. A gap in cover can mean you pay for care yourself.
- Plans often end on the last day of the month. Ask which end date applies to a request sent today.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a health insurance plan
Health plans end on set dates and often cover a whole household, so the request has to name the plan, every person on it and the date cover should stop, with new cover lined up first.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
