Questions about this tool
What is inside a ZATCA e-invoice QR code?
A Base64 text in TLV format (tag, length, value). Tags 1 to 5 hold the seller name, VAT registration number, invoice date and time, invoice total with VAT and the VAT amount. Phase 2 simplified invoices add tags 6 to 9: invoice hash, ECDSA signature, public key and the stamp signature.
Why does my ZATCA QR start with "AR"?
The first byte is tag 1 (the seller name) and the second byte is its length. Encoded in Base64 those first bytes often become "AR", so most valid ZATCA QR texts start that way.
How do I know if a VAT number in the QR is valid?
A Saudi VAT registration number has 15 digits and starts and ends with 3. The decoder checks this format automatically.
Is the Phase 1 QR from the generator valid for Phase 2?
No. Phase 2 (integration phase) QR codes must include the cryptographic hash and signature produced by your e-invoicing solution after onboarding with ZATCA. Use the generator for Phase 1 and for testing only.
Is my invoice data sent anywhere?
No. Decoding and QR generation happen in your browser. Nothing is uploaded.
