# Understanding the shipping verification APIs

This section describes how to use the [shipping verification endpoints](/avatax-for-bevalc/understanding-shipping-verification/verify-shipment/) to verify that transactions for alcoholic beverages are compliant with all alcohol shipping laws defined for the jurisdiction(s) where you are shipping to and to register those transactions.

## Requirements

-   Your AvaTax account must have Beverage Alcohol enabled in order to use these APIs.
-   Your Beverage Alcohol licenses must exist in eCompli. You can work with your Beverage Alcohol [account manager](https://help.avalara.com/Your_Account/Contact_your_account_manager) to set up licenses in eCompli.
-   A saved `SalesInvoice` or `ReturnInvoice` transaction must already exist in AvaTax in order use the shipping verification endpoints.

## Limitations

-   The AvaTax SDKs cannot be used for shipping verification.
-   These APIs are only supported for shipping to and from locations in the US.
-   For intrastate transactions, these shipping verification APIs currently apply intrastate rules.

**Important:**

-   Currently, compliance checks are only performed for the alcoholic beverage [tax codes](https://taxcode.avatax.avalara.com/) listed below. All other tax codes are unsupported and are assumed to be compliant.

    -   PA2020100: Packaged alcohol - spirits
    -   PA2020300: Packaged alcohol - wine
    -   PA2020301: Packaged alcohol - sparkling wine
    -   PA2020302: Packaged alcohol - fortified wine
    -   PA2020400: Packaged alcohol - hard cider and other flavored beverages
    -   PA2020500: Packaged alcohol - mixed alcoholic beverages

    ##### Checks for additional alcoholic beverage tax codes will be available in future releases.

-   These APIs can only be used with the `DTC` (direct-to-consumer) and `Retailer DTC` alcohol route types. Support for additional route types will be available in a future release.
