Other Buyer ID for a Foreign Customer

Hello ZATCA team,

As I understand it, when an invoice needs to be issued to a foreign customer (say based in Switzerland); the Other Buyer ID (BT-46) <cac:AccountingCustomerParty / cac:Party / cac:PartyIdentification / cbc:ID>.should be OTH and filled accordingly.

Now, for example, the official VAT Number for Switzerland is CHE-123.456.788 TVA. Since alphanumeric values are only expected under BT-46, should this value be sent as CHE123456788TVA?

We tried sending the OTH=CHE-123.456.788 TVA but received a 400.

@Yatin you can try sending it as it is, it should go through without any issues.

@Ankit.K.Tiwari thank you. We tried to send <cbc:ID schemeID=“OTH”>CHE-123.456.788 TVA</cbc:ID> and recieved a 400 response (BR-KSA-14).

Neither of the below expected formats are being accepted: CHE-123.456.788 TVA or CHE-123.456.788 MWST or CHE-123.456.788 IVA

How should we proceed?

@Yatin does it go through if you exclude special characters? If yes, please go ahead and provide the ID without special characters.
