Country Guides

E-invoicing requirements vary by country. This section covers country-specific requirements, identifier schemes, and compliance rules.

What the CIUS column means

This column names the national CIUS or format that applies in that country. It is not a statement about which Schematron packs GoRoute compiles and runs — for that, see Schematron packs GoRoute actually runs below.

Country-Specific Validation

GoRoute applies country-specific validation rules through the deep-validation endpoint. Both validation endpoints take a JSON body containing a canonical invoice — not raw XML.

Endpoint	Purpose
POST /api/v1/invoices/validate	Fast structural and business-rule check (dry run)
POST /api/v1/invoices/validate/deep	Full CEN EN16931 + Peppol BIS Schematron validation, or the PINT pack for a PINT document

import requests

response = requests.post(
    "https://app.goroute.ai/peppol-api/api/v1/invoices/validate/deep",
    headers={
        "X-API-Key": "your_api_key",
        "Content-Type": "application/json",
    },
    json={
        "invoice": invoice,           # CanonicalInvoice
        "include_schematron": True,
    },
)

result = response.json()
print(result["is_valid"], result["error_count"], result["warning_count"])

How the Schematron pack is selected

There is no cius query parameter, and receiver_country does not select one either.

Pack selection is driven entirely by the document itself. GoRoute reads the rendered invoice's cbc:CustomizationID:

• If it identifies a PINT jurisdiction that GoRoute has a compiled pack for, that PINT pack is run instead of CEN EN16931 — not in addition to it. The PINT pack already incorporates the adapted EN16931 rules.
• Otherwise the document is validated against CEN EN16931 + Peppol BIS 3.0.

DeepValidationRequest does accept an optional receiver_country. It feeds a national CIUS layer that is not implemented: the layer runs, finds nothing configured, and returns no pack. Setting it changes nothing about which Schematron runs.

Deep validation response

The response is a DeepValidationResponse:

Field	Type	Meaning
is_valid	boolean	False if any error or fatal finding
error_count	integer	Number of errors
warning_count	integer	Number of warnings
validation_time_ms	number	Validation duration
schematron_version	string	Schematron pack version applied
profile	object	Audit metadata: schematron_release_track, schematron_pack_checksum, cius_pack_ids_applied
errors	array	Findings with layer, identifier, identifier_type
warnings	array	Same shape as errors
score	integer	Compliance score, 0–100
ubl_xml_preview	string	Preview of the generated UBL XML if validation passes

cius_pack_ids_applied is always empty

The field exists on the response, but the national CIUS layer that would populate it is not implemented, so it is permanently an empty list. Do not use it as an audit trail of which national rules were applied. The audit fields that are actually populated are profile.schematron_release_track and profile.schematron_pack_checksum.

Compliance gate policy: error and fatal severities reject (is_valid: false); warning severity passes with a flag (is_valid: true, logged).

Schematron packs GoRoute actually runs

These are the packs compiled into the GoRoute validator image at build time. Anything not on this list is not validated by a national Schematron, whatever the country guide for that jurisdiction says about local requirements.

Pack	Source	Applies to
Peppol BIS 3.0 (PEPPOL-EN16931-UBL)	OpenPeppol	Baseline for every non-PINT document
CEN EN16931 (CEN-EN16931-UBL)	OpenPeppol	Baseline for every non-PINT document
PINT EU	OpenPeppol PINT eu	Documents whose CustomizationID is PINT EU
PINT Japan	OpenPeppol PINT jp	PINT JP documents
PINT Singapore	OpenPeppol PINT sg	PINT SG documents
PINT A-NZ Billing (v1.1.2)	OpenPeppol PINT aunz	PINT A-NZ billing documents
PINT A-NZ Self-billing (v1.1.2)	OpenPeppol PINT aunz-sb	PINT A-NZ self-billing documents
PINT Malaysia	OpenPeppol PINT my	PINT MY documents
PINT Oman	Copied into the image (not yet published by OpenPeppol)	PINT OM documents

No XRechnung, NLCIUS, Factur-X or FatturaPA Schematron is run

Earlier versions of this page listed XRechnung, NLCIUS and Factur-X as supported. That was wrong. Those packs are not compiled into the validator and no national Schematron runs for Germany, the Netherlands, France or Italy. Those documents are validated against CEN EN16931 + Peppol BIS 3.0 only. If you need national CIUS conformance today, validate against the national tooling as well.

Only PINT versions that OpenPeppol publishes on its A-NZ specification pages are stated above; the other PINT packs are pulled from OpenPeppol's current resources.zip at image build time and are not pinned to a version this documentation can quote.
