The store addresses section lists down any of your company’s addresses or locations. You can edit your default address under Settings > Store Addresses. In this section, it will list down your different site addresses, as well as the phone and email address for each location.
If you have multiple locations and want to show those locations on your contact page, you can enable the Show Locations option in Layout and Themes > Site Layout > Contact Us tab.
By enabling this option, you can show a link to the /locations page on your contact us page, so that users can view on Google maps exactly where each location is.
