Buyer account addresses and store address pages
Key Takeaway
Buyers can add or edit billing addresses in the store only when "Show all address types" is selected on the Address Form page. When it's deselected, buyers can add or edit only shipping addresses, even if "Show Address Type" on the Address List page is set to Shipping and billing.
In a B2B store, a buyer account's billing and shipping addresses are stored as Contact Point Address records on the account. Admins add these addresses on the buyer account and can mark one as the default. On the storefront, admins use Experience Builder to customize two pages, the Address List page and the Address Form page. These pages control what buyers can do with their addresses.
Buyer account addresses
Each Contact Point Address record has an "Address Type" of either "Billing" or "Shipping". Selecting "Is Default Address" on a record makes that address the default.
You set a buyer account's default addresses with these two fields. The default billing address is a Billing record with Is Default Address selected. The default shipping address is a Shipping record with Is Default Address selected.
