How do I permanent change ship from zip code for listing?

[luv2scan]

I have moved to a new address; I have changed all my address in my account settings. However, every time I post a new listing my old zip code shows shipping from.   I have been manually changing it with every new listing but it is becoming tedious.  How do i make my new zip code permanent?

Check the ship from address. Make sure your changes got entered.

yes all my addresses have been updated  including my ship from  but when posting it shows up with my old zip code

Go back and take a second look. Make sure it entered.
