Store name
The store name appears across your admin, storefront, and customer emails. Enter the new name and save; if the name is too short or too long, the form tells you the allowed length.
Store country
Pick your store's home country from the searchable list. When you change it, the admin offers to update your number format to that country's convention — you can accept or keep your current format.
Timezone
The timezone controls how times are shown for order timestamps, scheduled posts, and reports. Times are stored safely regardless of this setting — changing the timezone only changes how they're displayed.
