--- title: purchase.address-autocomplete.format-suggestion description: " \ An extension target that formats the selected address suggestion provided by a [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2025-07/targets/address/purchase-address-autocomplete-suggest) target. This formatted address is used to auto-populate the fields of the address form. \ It must return a [`formattedAddress`](/docs/api/checkout-ui-extensions/2025-07/targets/address/purchase-address-autocomplete-format-suggestion#addressautocompleteformatsuggestionoutput-propertydetail-formattedaddress). \ > Caution: \ > This extension target is only necessary if the corresponding [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2025-07/targets/address/purchase-address-autocomplete-suggest) target does not provide a `formattedAddress` for the suggestions. If a formatted address is provided with each suggestion, then this target will not be called. \ > \ > If the [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2025-07/targets/address/purchase-address-autocomplete-suggest) target is not implemented, then this target will not work. \ > Note: \ > - This target does not support rendering UI components. \ > - This extension can only be developed as a JavaScript extension using the `ui-extensions` library. \ > - The [app extension configuration](/docs/apps/app-extensions/configuration) `shopify.extension.toml` file is shared between this extension target and [`purchase.address-autocomplete.suggest`](/docs/api/checkout-ui-extensions/2025-07/targets/address/purchase-address-autocomplete-suggest).
