Israel TIN Validation
Validate Israel TIN / Company Number Online
Quickly and accurately validate Israel Tax Identification Numbers (מספר עוסק) and Company Registration Numbers (מספר חברה) issued by the Israel Tax Authority for businesses and individuals.
Understanding Israel TIN Format
The Israel Tax Identification Number (TIN) is a 9-digit code used for both individuals (Teudat Zehut — national ID number) and companies (Company Registration Number / H.P. number, ח.פ., issued by the Registrar of Companies). Both are validated against the Israel Tax Authority.
Digits
Check Digit
- ✓ Structure: Exactly 9 numeric digits for both individuals (Teudat Zehut) and companies (Company Number / H.P. number, ח.פ.). Company numbers always start with the digit 5. A Luhn (mod-10) check digit in the final position validates the number.
- ✓ Issuing Authority: Individual TINs are based on the national ID card (Teudat Zehut) issued by the Ministry of Interior; company numbers are issued by the Registrar of Companies (Israel Corporations Authority) and used by the Israel Tax Authority for VAT and corporate tax.
- ✓ Mandatory Use: Required on all Israeli tax invoices (חשבונית מס), government filings, and VAT-registered transactions. The TIN must appear on every fiscal document issued by a VAT-registered dealer.
