I'm a big user of Creative Common licenses and I often used https://creativecommons.org/choose/ in the past to find the right license to use.

However, I now see many suffixes for CC Attribution licenses like:

What are the differences?

Also is there a page that shows all CC licenses (including all these tiny variations) on a single page?

I imagine that there will be:

CC BY 2.0 Unported
CC BY 2.0 Generic
CC BY 2.0 International
CC BY 3.0 Unported
CC BY 3.0 Generic
CC BY 3.0 International
CC BY 4.0 Unported
CC BY 4.0 Generic
CC BY 4.0 International
CC BY-SA 2.0 Unported
CC BY-SA 2.0 Generic
CC BY-SA 2.0 International




For the latest version of the six main licenses, there are no ports. All of them are International:

(There might be 4.0 ports in the future: "CC expects that few, if any, ports will be necessary for 4.0.")

3.0 and earlier

For earlier versions, next to the international variant of a license (they are called Unported in 3.0, and Generic in earlier versions), there are ports for many jurisdictions.


(Ports shouldn’t be confused with translations of the human-readable summary page. For example, the summary for the USA port is also available in German.)

Relevant question: When to use a ported (instead of an international) CC 3.0 license?

  • Thank you for your answer. By the way "international" is a far better name than "unported" (the negative un- prefix sounds rather anxiogenic). – Basj Feb 21 '18 at 22:20
  • What about the Generic version? Is it equivalent to the unported/international versions? – waldyrious Feb 22 '18 at 8:17
