# The `orderCreate` mutation now supports multiple tracking numbers for each fulfillment

Affected APIs[Admin GraphQL API](https://shopify.dev/changelog?api_type=admin-graphql)[Admin REST API](https://shopify.dev/changelog?api_type=admin-rest)

We’ve added a `trackingNumbers` field to [`OrderCreateFulfillmentInput`](https://shopify.dev/docs/api/admin-graphql/latest/input-objects/OrderCreateFulfillmentInput), so you can attach multiple tracking numbers to a fulfillment when importing orders.

If you use the [`orderCreate`](https://shopify.dev/docs/api/admin-graphql/latest/mutations/orderCreate) mutation to import orders that ship in more than one package, you no longer need to update the fulfillment after creation to add additional tracking numbers. Instead, you can include all tracking numbers upfront when you create the order.

Use the `trackingNumbers` field to pass an array of tracking number strings, for example:

```graphql
trackingNumbers: ["1Z999AA10123456784", "1Z999AA10123456785"]
```

The `trackingCompany` value you provide applies to every tracking number in the array. This behavior is consistent with how [`FulfillmentTrackingInput`](https://shopify.dev/docs/api/admin-graphql/latest/input-objects/FulfillmentTrackingInput) already works on the `fulfillmentCreate` mutation.

If you provide both the singular `trackingNumber` and the plural `trackingNumbers`, the singular value takes precedence. In that case, the value of `trackingNumber` is used and `trackingNumbers` is ignored. This ensures that your existing integrations continue to work without any changes.

This field is available starting in API version **2026-10**.
