10 Essential Questions About TIN in Azerbaijan

Q: 2. What types of identifiers exist?

The Azerbaijani system bifurcates tax identity from civil identity, though they are linked in the ASAN Login ecosystem: Business TIN (VÖEN): A 10-digit number for companies, with the last digit being 1 . Individual TIN (VÖEN): A 10-digit number for individual entrepreneurs, with the last digit being 2 . Individual PIN (FIN): A unique 7-character alphanumeric code (Personal Identification Number) found on national IDs and passports.

Q: 3. What is the format of the TIN in Azerbaijan?

Azerbaijan uses a structured 10-digit system designed for algorithmic verification. VÖEN Structure: Exactly 10 numeric digits (e.g., 1525855851 ). Breakdown: The first two digits represent the region, digits 3-8 are a unique serial number, the 9th digit is a check digit, and the 10th indicates the type ( 1 for companies, 2 for individuals). PIN Structure: Exactly 7 alphanumeric characters (letters and numbers, excluding the letter "O"). Technical Insight: In 2026 , the e-taxes.gov.az portal performs an instant "Entity-Type" check. If you attempt to file a corporate return using a VÖEN ending in "2", the system will automatically reject the filing. TaxDo’s GSV (Global Syntax Validation) catches these suffix errors instantly to prevent structural data corruption in your ERP.
