The following table lists the possible responses to a validation request:

Response	Description
`tax-number-country-blocked`	This county is blocked in the settings.
`tax-number-validation-not-available`	The service was not able to validate this number.
`tax-number-ignored`	The number is ignored because the settings have been changed to block numbers for this region, country or seller.
`tax-number-syntax-valid`	The syntax of the ID is valid. However, no further validations were done. In cases where a checksum is required, like for India, the ID is considered valid if the syntax is valid and the checksum is not configured.
`tax-number-syntax-invalid`	The syntax of the ID is invalid.
`tax-number-syntax-considered-valid-but-not-verified`	The syntax of the ID is valid. However, no further validations were done.
`tax-number-considered-valid-in-domestic-country`	The Tax ID is valid in the domestic country of the supplier.
`tax-number-valid-according-to-external-service`	The Tax ID has been validated against the Tax Authority's database of Tax IDs and is valid.
`tax-number-invalid-according-to-external-service`	The Tax ID has been validated against the Tax Authority's database of Tax IDs and is invalid.
`tax-number-validation-requested-additional-interactions`	The Tax Authority has requested additional parameters. For example, a country might require CAPTCHA validation and needs more information before they can validate the ID.
`tax-number-service-temporarily-unavailable`	Could not connect to validation service due to temporary unavailability of the service.
`tax-number-syntax-considered-valid-but-not-verified`	The Tax ID syntax is valid but the ID's status could not be verified by the external service. This occurs when the `on-error` settings is set to `syntax-check` and external service does not respond
