Warning

UBL-CR-377: No time zone offset element in the delivery address

In short

Warning: worth checking.

UBL-CR-377 means the delivery address contains a time zone offset element (cbc:TimezoneOffset), which EN 16931 does not use. Remove the element from the delivery address and recheck the file.

On this page

What it means

This rule checks the delivery address (BG-15) and warns if it contains a time zone offset element (cbc:TimezoneOffset inside cac:Delivery/cac:DeliveryLocation/cac:Address). This gives the location's time difference from UTC, rather than a named time zone. EN 16931 has no separate field for it. The check applies to invoices and credit notes.

Why it matters

EN 16931 does not use a time zone offset element in the delivery address.

How to fix it

Check whether your invoicing software or export template adds a time zone offset to the delivery address, and remove it from the export. If you build the XML yourself, delete cbc:TimezoneOffset from cac:Delivery/cac:DeliveryLocation/cac:Address. Recheck the corrected file.

Once the file is corrected, check it again for free: Validate an invoice against EN 16931

Or fix the invoice in a form and download the corrected file, for 1 credit: Fix a rejected e-invoice
