ZATCA QR code decoder

Upload a photo or screenshot of the QR on a Saudi e-invoice, or paste its text, and see what it carries. Nothing is uploaded: decoding happens in your browser.

What a ZATCA QR code contains

The QR on a Saudi e-invoice is base64 text in TLV form (tag, length, value). Phase 1 invoices carry five fields; Phase 2 simplified invoices add four more for the cryptographic stamp:

1. Seller name
2. Seller VAT number
3. Invoice time stamp
4. Invoice total with VAT
5. VAT total
6. Invoice hash (Phase 2)
7. ECDSA signature (Phase 2)
8. Public key (Phase 2)
9. Signature of the stamp's certificate (Phase 2, simplified invoices)

Decoding shows what the QR says; it does not prove the invoice is genuine. To check the whole invoice against ZATCA's rules, paste the XML into the validator.
