Hi David, 

Thanks for suggesting this. It's my understanding (and please correct me if I am wrong) that you are wanting to be able to do two things on the Ready to Ship screen: 

1. The ability to add or remove a ship-from zip code. 
2. The ability to edit a ship-from zip code. 

To clarify, we do offer the ability to set a separate ship-from zip code for each order. However, it is store-based, which may not work for you. If you were interested in assigning ship-from zip codes to your stores, however, you can do so by following this guide: Can I ship from my location, but have the return address say a different organization?

Some of our customers also allow their suppliers access to ShippingEasy, creating a different user for each. If this was something you'd be interested in, we also have this alternate forum post requesting more permissions per-user and the ability to set ship-from zip codes based by user. Here's a thread on that: Assigning same return address to users with different origination zip codes

I've gone ahead and added your request to edit/add/delete ship-from zip codes from the Orders page to our list of enhancements to consider. Please feel free to follow this thread should we have any updates on the matter. Additionally, if you see anyone in the forums who you think may benefit from this, you can go ahead and send them to this thread to comment and like. Thanks! 

Yes, I understand that but it is way too cumbersome when you are doing a lot of them.

Hi David,

I completely understand and agree that it's cumbersome to do it this way if you have many different drop shipping locations. Thanks for confirming your business' needs.

This hasn't happened yet, I still need the ability to change the ship from zip code without going into the settings and updating it for my whole store and then switching it back when finished. We end up sending a lot of packages from the incorrect zip code because it is so cumbersome.
