All Portuguese Invoices Must Include a QR Code and ATCUD Code

The Portuguese tax authority (Autoridade Tributaria e Adueneira - AT) announces a new requirement to include a unique document code ATCUD (Sequential Number Validation Code) and a two-dimensional bar code (QR code) in invoices and relevant tax documents.

This measure aims to simplify the communication of invoices and better monitor taxpayer transactions, thus combatting the informal economy, fraud, and tax evasion.

The change affects all electronic invoice issuers in Portugal, who will have to adapt their invoicing systems to the new government requirements.

As of January 1st 2023: 

• Relevant Invoices and tax documents must include the document code ATCUD.

Unique Document Code (ATCUD) and Two-Dimensional QR Code

ATCUD Codes included on invoices must be legible regardless of the medium in which it is presented to the customer, including invoices in both electronic and printed format. The representation of the QR code will only affect invoices that are presented in paper or signed PDF.

In documents with multiple pages, the ATCUD code must appear on each. The QR code can be placed either on the first or last page.
