UBL-CR-421
What does UBL-CR-421 mean? A UBL invoice should not include the PaymentMeans CardAccount CardChipCode
Why did my invoice fail UBL-CR-421?
EN 16931 defines a fixed semantic model, and any UBL element outside that model must not be used. This rule flags the cac:PaymentMeans/cac:CardAccount/cbc:CardChipCode element, which has no corresponding business term in EN 16931, so a compliant invoice should not include it. EN 16931 limits payment card information (BG-18) to the account number, network and holder name; sensitive or technical card fields are excluded.
Official rule text
A UBL invoice should not include the PaymentMeans CardAccount CardChipCode
Common causes
- ERP or e-invoicing software exports the full UBL 2.1 schema instead of the EN 16931 subset
- A mapping template copies every source field into UBL without filtering to the EN 16931 element list
- Reusing an invoice template from a non-EN 16931 UBL profile that populated this element
