How to cancel Librus by mail
Start with 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 Librus has on file.
Draft the request
Librus is based in Poland, so the letter goes out in Polish, built from our Polish template. Subject line: “Temat: Prośba o anulowanie – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send the letter by certified mail
Mail the letter by certified mail to the Katowice address in the next section, and keep the tracking number.
Keep the delivery receipt
It shows the date Librus received your letter. Check your next statement: no Librus charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Librus cancellation letter goes
Written requests to Librus go to Al. Korfantego 193, 40-153 Katowice, Poland.
Copy the postal code 40-153 exactly: it is what routes the letter to Śląskie, Poland.
Your details go in a block headed by Posiadacz konta, Adres rozliczeniowy w systemie and E-mail w systemie, and the opening line is “Szanowni Państwo,”.

Before you cancel Librus, 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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
