You want to know if it is possible to use a location code in Magento, so a location is assigned to transactions in the admin console.
- You can hard code a single location code in Magento, but all transactions for that store will use the same location code:
- In Magento go to System > Configuration > Sales > Tax
- Under AvaTax: Data Mapping enter the code in "Location Code" then Save
This field is optional and will show as the location code for orders.
