How to cancel SWICA by mail
Get your account details together
Check the member or policy number, the full name of the policyholder and the date you want the plan to end before anything else. A request that does not match the account on file at SWICA is the easiest one to set aside.
Write your request
Postbye drafts the request in German, the language of Switzerland, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks SWICA to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Mail the letter by certified mail to the Winterthur address in the next section, and keep the tracking number.
Hold on to the receipt
File the receipt with the letter. A SWICA 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 SWICA cancellation letter goes
SWICA can be reached by post at Römerstrasse 38, 8401 Winterthur, Switzerland.
The envelope is going to Winterthur in Noord-Holland, Switzerland, so the postcode 8401 must be on the front.
The letter greets the reader with “Sehr geehrte Damen und Herren,”; your own details sit under the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel SWICA, check these
- List every dependant on the plan. Ending the policyholder's cover can end theirs too.
- 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.
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.
