(1=legal, 2=natural)
- ✓ 10 Digits Exactly: The VÖEN always consists of exactly 10 numeric digits with no separators — the first two digits identify the territorial unit, the next six form a serial number, the ninth is an algorithmic check digit, and the tenth marks the taxpayer type (1 for legal persons, 2 for natural persons). Leading zeros are significant and must be preserved when transmitting the identifier.
- ✓ Issued by the State Tax Service: The State Tax Service under the Ministry of Economy of the Republic of Azerbaijan (successor to the former Ministry of Taxes) is the sole authority that issues and maintains VÖEN records, covering all legal entities and registered individuals in the country.
- ✓ Mandatory on Tax Documents: Every VAT invoice, customs declaration, and official tax communication in Azerbaijan must display the VÖEN of both the issuing and receiving parties to be legally valid.

What data is returned on VÖEN validation?
A successful VÖEN validation via Lookuptax returns the full legal name of the registered entity, registration status (active / suspended / deregistered), entity type (LLC, JSC, branch, individual, etc.), and the address on record with the State Tax Service. This data is invaluable for KYC, supplier due diligence, and automated invoice enrichment workflows. Sign up free to access structured responses via API.
What if the VÖEN is invalid or inactive?
An invalid VÖEN fails basic format checks (wrong length or non-numeric characters), while an inactive one means the entity has been liquidated, suspended, or removed from the register. Azerbaijani tax law disallows VAT deductions on invoices from deregistered entities. Lookuptax proactively detects both conditions and surfaces a clear status flag, enabling your finance team to reject problematic invoices before they enter your accounting system.
