My State is not accepted during online shopping

Hi everyone,

I am Aisha from Germany. I am first time buying anything from Apple online store.

I checkout and start filling delivery address, but when I reach the section where I have to put my State name, it rejects it. It seems like I have to write the abbreviation of the state. Like my state name is Saxony with SN abbreviation. I correctly put it in the space given, but not accepted. What could be the problem?

In my apple account I have Germany as my country or region so that is not a problem. I am clueless. Please help me.

Aisha!
