The seller address building number must contain 4 digits.Warning · Source: ZATCA E-Invoicing SDK 238-R3.3.8 · Electronic Invoice XML Implementation Standard v1.2, 19 May 2023, §13.3.1, p. 56 · Checked: 26 October 2026
What it means
The building number in the seller address must be exactly 4 digits, as in the national address.
When it happens
- The number was entered as 3 digits, dropping a leading zero.
- The building number field holds the additional number or a building name.
- Arabic-Indic digits instead of Western digits.
How to fix it
- Copy the building number from the national address as it is: 4 digits.
- Write it with the digits 0 to 9.
- Put the additional number in its own field, not in the building number.
Example
<cbc:BuildingNumber>232</cbc:BuildingNumber>
<cbc:BuildingNumber>2322</cbc:BuildingNumber>
We ran the wrong example through ZATCA's SDK 238-R3.3.8 on 26 October 2026 and it raised BR-KSA-37. The example is an excerpt of ZATCA's sample Simplified/Invoice/Simplified_Invoice.xml with one change; the sample without it does not raise the code.
