Why am I receiving the error "An Address is Incomplete or Invalid" in AvaTax?
Overview
When calculating tax, you receive the error "An Address is incomplete or invalid"
Environment
Avalara AvaTax
Resolution
-
This error indicates an address being sent to Avalara is partially completed, in a format that cannot be recognized, or does not have enough information to determine tax jurisdictions
-
We require a minimum of State and Postal Code for US and Canadian addresses
-
However a full address (Street address, city, state, and zip code) will return the best tax calculation
-
-
For international transactions, the two digit ISO country code is required to determine tax jurisdictions
-
-
This occurs most often with your company address (origin), so we recommend reviewing all company addresses and Location Codes associated with the transaction for complete addresses.
-
Review the customer address and shipping location to confirm they are complete as well
-
Once all addresses are reviewed and corrected, recalculate tax
-
Depending on your accounting system you may need to re-select the customer to update the sale with the new address
-
Usually this requires selecting a different customer, then choosing the correct one again to update the transaction
