BR-KSA-F-13: Seller/buyer ID must not be a placeholder digit sequence

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

Looks at seller and buyer cac:Party/cac:PartyIdentification/cbc:ID values whose schemeID is an allowed scheme (seller: CRN, MOM, MLS, 700, SAG, OTH; buyer: TIN, CRN, MOM, MLS, 700, SAG, NAT, GCC, IQA, OTH, PAS). A warning is raised when an all-digit value contains 8 ascending digits (01234567, 12345678, 23456789), 8 descending digits (76543210, 87654321, 98765432) or the same digit 8 times in a row. The test shown is a variable holding this failure condition.

How to fix it

Enter the party's real identification number instead of a test or placeholder value such as 1234567890 or 0000000000.
