The address of your store is set when you set up your first store, but can be changed at any time.

If you navigate to your dashboard, you can find the screen at

Stores > Store Settings > General

Scroll down to the Store Address section to update it, and click Save.

Address Changes & Delivery

If you have a delivery radius set for your store, the post code is used to calculate the delivery radius.

The delivery radius should automatically change to the postcode you’ve reset to, so there’s no need to take any further action.
