# Subscription shipping address phone validation

As of the 2022-07 version of the Admin GraphQL API, the `phone` field of the delivery address will be validated on calls to `subscriptionContractCreate` and `subscriptionDraftUpdate`.

This allows you to ensure phone numbers are properly formatted and will prevent errors that may occur when processing subscription payments with invalid data.

Learn more about [SubscriptionContractCreate](https://shopify.dev/api/admin-graphql/unstable/mutations/subscriptionContractCreate) and [subscriptionDraftUpdate](https://shopify.dev/api/admin-graphql/unstable/mutations/subscriptionDraftUpdate) on Shopify.dev.
