E-invoice rule our own check at ARLing, not from a schematron

ARL-ICDPH: We expect SK followed by 10 digits, for example

We expect SK followed by 10 digits, for example SK2020000000.

Original wording of the rule

This is our own check, not a rule from a schematron. That is why no external wording is quoted here.

How to fix it

1. Open the XML file and find the element cac:PartyTaxScheme/cbc:CompanyID.
2. Add or correct the element the way the wording of the rule above asks for.
3. Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.

A correct UBL 2.1 snippet

<cac:PartyTaxScheme
    xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:CompanyID>SK2120000001</cbc:CompanyID>
</cac:PartyTaxScheme>

The snippet is only the part of the document the rule is about. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.

Related rules

• ARL-DATUM-PORADIE The payment due date (…) is earlier than the issue date (2026-09-11)
• ARL-IBAN Check the account number for a typo
• ARL-LEITWEG The buyer reference "…" looks like a German Leitweg-ID but does
• ARL-MENA The element cbc:Amount carries the currency USD while the invoice
• ARL-PROFIL We ran the EN 16931 core rules only, without the Peppol and XRechnung

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. Licences for the quoted wordings are listed in our sources.
