# Optional Address Validation in Storefront API

As of Storefront API's 2024-04 release, you can use `buyerIdentity.deliveryAddressPreferences.deliveryAddressValidationStrategy` (accepted values `STRICT` or `COUNTRY_CODE_ONLY`) to enable address validation on the passed `deliveryAddress` for any cart mutations that accept a buyer identity as input (like `cartCreate`or `cartBuyerIdentityUpdate`).

Passing `STRICT` will perform a full validation on the address fields, and will raise `CartUserError`s for invalid addresses. Invalid addresses will not be stored on the cart.

Passing `COUNTRY_CODE_ONLY` or omitting the field will only validate the presence of a valid country in the address (unchanged behavior from previous version).
