What is in a ZATCA QR code?

For Phase 1: the seller's name, the seller's VAT registration number, the invoice time stamp, the invoice total including VAT and the VAT total, as tags 1 to 5. Phase 2 adds the XML invoice hash, the ECDSA signature, the public key and, for simplified invoices, the signature of the cryptographic stamp, as tags 6 to 9.

Can I use this for Phase 2 invoices?

Not to produce them. Tags 6 to 9 need the signed XML invoice and the cryptographic stamp that ZATCA issues to an onboarded e-invoicing solution, so a browser tool cannot create them. You can decode a Phase 2 QR code to read its tags.

Is an invoice PDF with this QR code ZATCA compliant?

No. A Saudi tax invoice must be generated by a compliant e-invoicing solution as structured XML. A PDF from a browser tool, even with a QR code, is not a ZATCA e-invoice.

What format should the time stamp have?

ISO 8601, such as 2026-10-30T10:00:00Z for UTC. Saudi invoices often use local time with +03:00 instead of Z.

Is there a size limit?

The Base64 text may be at most 700 characters, and each value at most 255 bytes, because its length is stored in a single byte.

Is my invoice data uploaded?

No. Encoding and decoding run entirely in your browser and nothing is uploaded. This tool does not keep a draft in your browser.

ZATCA QR code generator and decoder

A ZATCA QR code is the code on a Saudi simplified tax invoice that holds the seller's name, VAT number, invoice time, invoice total and VAT total as Base64-encoded TLV (tag, length, value) data.

Encode the five Phase 1 ZATCA QR fields (seller, VAT number, time, total and VAT) as TLV Base64, or decode an invoice's QR text to check what it holds.

This makes the Phase 1 fields only (tags 1 to 5). A Phase 2 QR code also needs the invoice hash, signature and public key from a ZATCA-onboarded e-invoicing solution, and a PDF with this QR code on it is not a ZATCA e-invoice.

Phase 2 (integration) e-invoices also need tags 6–9 from the device's ZATCA cryptographic stamp, so this QR alone is not a compliant Phase 2 invoice. It encodes the Phase 1 fields (tags 1–5).

Examples

The five fields as TLV

Tag 1 seller name, tag 2 VAT number, tag 3 time stamp, tag 4 total with VAT, tag 5 VAT total. Each is written as one byte for the tag, one byte for the length and the value's UTF-8 bytes.

The sample invoice

Acme Trading, VAT number 300000000000003, 2026-10-30T10:00:00Z, total 115.00 and VAT 15.00 make 68 bytes, which encode as AQxBY21lIFRyYWRpbmcCDzMwMDAwMDAwMDAwMDAwMwMUMjAyNi0xMC0zMFQxMDowMDowMFoEBjExNS4wMAUFMTUuMDA=.

Arabic seller names

The length byte counts UTF-8 bytes, not characters. An Arabic letter takes two bytes, so a 10-letter Arabic name has a length of 20.

Decode to check a QR code

Paste the Base64 text read from an invoice's QR code and switch to Decode to see each tag and value, and whether Phase 2 tags 6 to 9 are present.

How to use it

Choose Encode to make QR text, or Decode to read one.
To encode: enter the seller's name, VAT number, invoice time stamp, invoice total with VAT and VAT total.
To decode: paste the Base64 text from the QR code.
Read the fields and the QR code, then download the SVG or copy the Base64.
