# Display and store the AvaTax user's VAT code in responses

Learn how AvaTax includes and uses the user's VAT code in transaction responses for specific countries.

**Element type:**

-   Required (for VAT ERP)
-   Suggested (for VAT Ecommerce and marketplace)

**Endpoints/models used:** N/A

In certain transactions, AvaTax will include in the response the VAT ID of the AvaTax user creating the transaction. Specifically, this occurs in AvaTax transactions between the following countries:

-   AU

-   CH

-   EU Countries

-   GB

-   IN

-   JP

-   NO

-   NZ

-   SG

-   XI

AvaTax generates the `avtUserBIN` code based on the company settings and the transaction details. Your integration display and store this code in the transaction record so that it can then be used in VAT Reporting. This requirement is handled through your back end and not directly via an AvaTax API call.

**Example**

```
"details": [
  {
   ...
    "reportingTaxCalculated": 14.17,
    "avtUserBIN": "FR123456789",
    "liabilityType": "Seller"
  }
]
