How can I remove the state (Bundesland) field completely in a German shop?

Question

When using Market Ready Germany there was such an option. But we use German Setup.

Is there a clean and easy solution to remove this field fully from the system?

Answer 1

From Magento CE 1.7 you should go into System->Configuration->General->State Options; unselect Germany from countries list and set Display not required State to "No"

If your version is older than 1.7 you need to use an extension, I used this one Remove/Disable or Change Displayed States and Regions
