Check a VERI*FACTU QR code

You can check the tax QR code on a Spanish invoice by dropping a photo, a screenshot or the PDF, or by pasting the link the code holds. Klarbon reads it on your device and checks it against the AEAT's specification: the address, the NIF, the series and number, the date, the amount and the encoding. Then open the code's own link to confirm the invoice with the AEAT.

What does the check cover?

The QR code is a link to the AEAT's invoice check, with four values: the issuer's NIF, the series and number, the issue date and the total (AEAT specification, in Spanish). Klarbon checks:

• that the link goes to the AEAT over https, and not to its test portal;
• each value: a 9-character NIF with a correct check character, a series and number of up to 60 characters, a date written DD-MM-YYYY, and an amount with a full stop and at most two decimals;
• the encoding: values written in printable ASCII, with an & inside a value encoded as %26, as the AEAT asks;
• whether the code comes from a VERI*FACTU system or from one that does not send its records as invoices are issued;
• the code itself: error correction level M, as the specification requires.

What the check does not show

A code that passes is well formed. It does not show that the AEAT holds the invoice, that the invoice was issued by the business named, or that the amounts in it are right. Only the AEAT can answer that, through the link in the code. Klarbon shows that link and does not open it for you.
