In the Zuora integration (created by Zuora) addresses for Washington DC are frequently failing to calculate, indicating the address is not correct, but the address is correct.
Zuora is passing AvaTax "Washington DC" as the state/region, not "DC". The city name is "Washington". This is causing address failures if the street address and zip code combination is not good enough for us to determine the location.
- Validate the address, using the USPS website, or something similar.
- Make the ship to street address match what the validated address shows.
- Rerun/recreate the bill run.
