BR-KSA-F-07: Buyer TIN must be 10 digits starting with 3

Explained by Matheel from ZATCA's rule text and the condition SDK 3.4.8 executes · Updated October 24, 2026

Warning: accepted with a warningConditional, see belowFields: BT-46

When the buyer's cac:AccountingCustomerParty/cac:Party/cac:PartyIdentification has cbc:ID with schemeID='TIN', the value must be exactly 10 digits starting with 3; otherwise a warning is raised. In the validator this test is the failure condition: the expression shown is TRUE when the value is wrong.

How to fix it

Put the correct Tax Identification Number as exactly 10 digits starting with 3, e.g. <cbc:ID schemeID="TIN">3105293847</cbc:ID> with no letters, dashes or spaces. If the number you have does not fit this shape, check that the schemeID is the right one.
