Why is the serial number invalid or revoked?

Adobe blocks serial numbers that have not been issued by Adobe, or have been used fraudulently by unauthorized sellers to produce counterfeit software. Unfortunately, you may only know the serial number has been blocked for this reason when re-activating or reinstalling Adobe software. 

What should I do if the serial number is invalid or revoked?

Do the following if you receive the "Invalid serial number" or "Revoked serial number" message:

  1. Check that you are using the correct serial number for your product installation. See Find your serial number


    A serial number has only 24 numbers. Here is an example of the serial number format: 8721-0892-0867-4459-9223-2874.

  2. If the serial number associated with the software is blocked, find information on this page to quickly resolve the issue.
