How to cancel Concordia by mail
Find your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Concordia has on file.
Prepare the letter
Postbye drafts the request in Dutch, the language of Netherlands, with “Onderwerp: annuleringsverzoek – [your name]” as the subject line. It asks Concordia to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 1083 HM Amsterdam-Zuid. Keep the tracking number it gives you.
Keep proof the letter arrived
File the receipt with the letter. A Concordia 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 Concordia cancellation letter goes
For a letter to Concordia, use Tommaso Albinonistraat 7, 1083 HM Amsterdam-Zuid, Netherlands.
The envelope is going to Amsterdam-Zuid in Noord-Holland, Netherlands, so the postcode 1083 HM must be on the front.
Your details go in a block headed by Accounthouder, Factuuradres in dossier and E-mailadres in dossier, and the opening line is “Geachte heer/mevrouw,”.

Before you cancel Concordia, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
