FatturaPA (Italy / SdI)

00425

Numero documento non valido

What it means

The invoice number (DatiGeneraliDocumento/Numero) must contain at least one numeric digit. SdI rule 00425 rejects purely alphabetic numbers.

How to fix it

Include the running number in the Numero value, e.g. '2026/123' or 'INV-000123'.

Catch this before it reaches the SdI:

# CLI
npx @eleata/validate-einvoice validate invoice.xml --format fatturapa

# GitHub Action — fail the build on any invalid invoice
- uses: hernaninverso/validate-einvoice-action@v1
  with:
    files: invoices/**/*.xml
    api-key: ${{ secrets.EINVOICE_API_KEY }}
