BR-KSA-F-08: Seller/buyer CRN must be exactly 10 digits

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-29, BT-46

When the seller's or buyer's cac:Party/cac:PartyIdentification (cac:AccountingSupplierParty or cac:AccountingCustomerParty) has cbc:ID with schemeID='CRN', the value must be exactly 10 digits; 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 commercial registration number as exactly 10 digits, e.g. <cbc:ID schemeID="CRN">1105293847</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.

[BR-KSA-F-08] - The value provided in Other Seller ID (BT-29) or Other Buyer ID (BT-46) for the scheme ID 'CRN' appears to be incorrect. Please recheck the value to avoid non-compliance.
