Where to send your Kaspersky cancellation letter
Read the addresses on this page next to the full guide to cancelling Kaspersky.
The addresses we hold
One place for Kaspersky's mailing addresses: the Woburn delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.
Where the letter goesMailing address
Kaspersky500 Unicorn Park Dr#300Woburn, MA 01801The head-office address for Kaspersky, in Massachusetts. ZIP code 01801.
How to address the envelope
Copy the address exactly
Copy 500 Unicorn Park Dr, #300, Woburn, MA 01801 letter for letter. A wrong digit in 01801 is enough to send the letter on a detour.
Add the return address
Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.
Send it by certified mail
Certified mail is bought at the post office: hand the letter to a postal employee, keep the postmarked receipt, and follow the article number until the delivery shows.
Keep the records
Keep your copy of the letter, the receipt and the delivery record in one place. Because Cancelling auto-renewal keeps the subscription active until the paid period ends, the date on the receipt is the date that matters.
The letter to send
What the letter to Kaspersky says: one clear cancellation request, no reasons given, the account or subscription number, the email the plan was bought with and the address or devices it covers quoted, and a request for written confirmation.
