supplied.identificationNumber accepts one of the identification numbers below depending on the type of supplied party. All identification numbers must contain digits only, without hyphens (-).
Supplied Party with a Foreign Registration Number
The standard issuance API accepts a 13-digit foreign registration number as the supplied party’s identification number. The reverse issuance API’s supplied party identification number still allows only a business registration number, as before. In the request body, enter the actual foreign registration number insupplied.identificationNumber. During issuance processing, the identification number is converted to match the NTS (National Tax Service) foreign supplied party format, and the foreign registration number you entered is reflected in the tax invoice’s remarks.
For a foreign registration number supplied party request, you cannot enter the tax invoice remarks (description) directly. If you pass description, a 400 validation error is returned, so send it as null or omit the field.
If the supplied party’s identification number is not a business registration number, supplied.taxRegistrationId must also be sent as null or omitted.
Passport numbers are not currently supported. A passport-like value such as M12345678 cannot be used as the supplied party’s identification number.
