ZATCA QR Code Generator & Decoder

Generate a ZATCA-compliant QR code for a Saudi simplified tax invoice (Phase 1 TLV Base64) or decode an existing one — free, instant, runs in your browser.

Base64 TLV string—

In short

A ZATCA simplified tax invoice QR code encodes five TLV fields — seller name, VAT number, timestamp, invoice total and VAT amount — as a Base64 string. Each field is a one-byte tag, a one-byte length and the UTF-8 value.

Who this is for: Saudi businesses and developers generating or checking the QR code on a ZATCA simplified tax invoice.

Not tax or legal advice. This tool generates the TLV/Base64 structure for simplified-invoice QR codes per publicly documented ZATCA specifications. It does not include cryptographic invoice signing required for Phase 2 (integration phase) compliance. Confirm your specific e-invoicing obligations with ZATCA or a qualified consultant.

What is a ZATCA QR code?

Since Phase 1 of Saudi Arabia's e-invoicing (Fatoora) mandate, every simplified tax invoice (typically B2C, point-of-sale) must carry a QR code encoding five fields in TLV (Tag-Length-Value) format, then Base64-encoded:

  • Tag 1: Seller name
  • Tag 2: Seller VAT registration number
  • Tag 3: Invoice timestamp (ISO 8601)
  • Tag 4: Invoice total (with VAT)
  • Tag 5: VAT total

Each field is encoded as: 1 byte for the tag number, 1 byte for the UTF-8 byte-length of the value, then the value itself. All five fields are concatenated and the result is Base64-encoded to produce the string embedded in the QR code.

This tool builds that TLV structure in your browser and renders it as a scannable QR code — and can also decode an existing ZATCA QR string back into its five fields.

Source: ZATCA — E-Invoicing (Fatoora).

Assumptions

  • The QR encodes the five mandatory TLV tags (1–5) only; cryptographic tags 6–9 for standard invoices are not generated.
  • Timestamp must be entered in ISO 8601 format.
  • Everything runs in your browser; nothing is sent to ZATCA.

Worked example

Simplified invoice, SAR 1,150 total (SAR 150 VAT)

Seller: Al Farazm Trading Co. · VAT: 311111111100003 · Total: SAR 1,150.00 · VAT: SAR 150.00
The tool builds the 5-field TLV byte string, Base64-encodes it, and renders it as a QR code your invoicing system or till receipt can embed.

Frequently asked questions

Is this the same as a full Phase 2 e-invoice?

No. This covers the simplified-invoice QR structure (Phase 1). Phase 2 (integration phase) requires invoices to be cryptographically signed and cleared/reported through ZATCA's platform — this tool does not generate a cryptographic stamp and is for simplified/offline testing and learning purposes.

Can I use this QR code on real invoices?

For businesses in scope of Phase 2 integration, you must generate QR codes through ZATCA-compliant invoicing software that includes the required cryptographic stamp — this free tool is not a substitute for that. It's useful for understanding the format, testing, or for very small simplified-invoice use cases where Phase 2 does not yet apply to you.

Does my data get uploaded anywhere?

No — everything is generated and decoded in your browser. Nothing is sent to any server.

Is the QR code enough for Phase 2 (integration) compliance?

No. Phase 2 standard invoices require the additional cryptographic tags and clearance through ZATCA's platform; this tool covers the five basic tags used on simplified invoices.

Can I decode a QR from a supplier's invoice?

Yes — paste the Base64 string to see the seller, VAT number, timestamp and totals encoded in it.
