Enter 15 continuous digits. Spaces and dashes are auto-stripped.
How does it work?
Every VAT-registered business in Saudi Arabia has a 15-digit Tax Identification Number (TIN). A valid TIN on every tax invoice is mandatory for the invoice to be accepted by the Zakat, Tax & Customs Authority.
Structural rules
- Exactly 15 digits, numbers only.
- Starts with the digit 3 (reserved for VAT).
- Ends with the digit 3 (terminal check digit).
- Contains no spaces, dashes, or other symbols.
Structural-only validation
This tool only validates the format of the VAT number — it doesn't call the Zakat Authority's registry. To verify active registration, use the official ZATCA portal.
When do you need this?
Before issuing a tax invoice to a customer, when receiving an invoice from a new supplier, and when on-boarding supplier/customer master data into accounting software. Catching typos here prevents rejected invoices later.
Frequently Asked Questions
Does the tool query the ZATCA database?
No — it's a structural check only (15 digits, starts with 3, ends with 3). For active-registration verification, use the official ZATCA portal.
What's the Saudi VAT number format?
15 numeric digits, starts with 3 and ends with 3. Example: 300000000000003.
What if I have fewer or more digits?
The tool rejects it and indicates that the length must be exactly 15 digits.
Does it accept spaces or dashes?
Yes — they're stripped before validation. But the value stored on invoices must be a continuous numeric string.
How is this different from the Commercial Registration (CR)?
Completely different. CR is a 10-digit number issued by the Ministry of Commerce. VAT TIN is 15 digits issued by the Zakat, Tax & Customs Authority.
