First, thanks for your support! We truly couldn't do this without you.

You can find your Order ID on the thank-you email we sent to the address you provided when you paid for AdBlock.

Did you accidentally delete that email? If you paid by PayPal, we can search for your payment using the email address associated with your PayPal account. If you paid by credit card, we can find it using the last four digits of the card number and the payment date and amount. Just open a ticket on our support site and we'll be happy to look it up for you.

Did you come to this article because you need to reinstall AdBlock?

We want you to know that while we are grateful for every donation, you are never obligated to pay for AdBlock. AdBlock is completely free. If you ever need to reinstall AdBlock, you don't need an Order ID to prove you already paid for it. You don't need to pay again. You don't need to pay at all. Just go ahead and reinstall it.

If you have AdBlock Premium, however, you do need to activate your license if you reinstall it. If you don't have your license key handy, we can look it up for you. Just send us an email at
