Tip

The invalid_region error code will be returned if you attempt to create or update a shipment but provide an invalid region for an address.

This error code will be returned, for example, if you attempt to create a shipment with a country_iso_code of US but do not provide a valid US state in the region property, e.g.:

{
  "addresses": [
    {
      "address_type": "destination",
      "country_iso_code": "US",
      "region": "Lancashire"
    }
  ]
}

Note

Not all countries have formally-recognised regions and therefore this property will not be validated or checked in all cases. However, the value will be checked for the following countries:

• GB - Great Britain
• IE - Ireland
• US - United States of America
• AU - Australia
• CA - Canada
