Azerbaijan VÖEN Format Checker
Check that an Azerbaijani VÖEN (Vergi ödəyicisinin eyniləşdirmə nömrəsi) has 10 digits and a valid taxpayer-type digit.
What is an Azerbaijani VÖEN?
The VÖEN (Vergi ödəyicisinin eyniləşdirmə nömrəsi) is Azerbaijan’s 10-digit taxpayer identification number, issued by the State Tax Service. It is also the VAT number. The last digit shows the taxpayer type — 1 for a legal person, 2 for a natural person — as in 1401555071 for the State Treasury Agency.

Example: 1401555071 (the State Treasury Agency, as printed on the State Tax Service’s own budget-details page).
- Check digit: Calculated by an unpublished algorithm, so it is not tested here.
- Individuals: A natural person’s VÖEN ends in 2 and is personal data, so this page uses an official example only.
- Format check only: This checker tests the length and the taxpayer-type digit. It does not query the State Tax Service, so it cannot confirm that the VÖEN is registered or that the business pays VAT.
How to check an Azerbaijani VÖEN
- 1 Find the VÖEN on the supplier’s invoice (hesab-faktura or e-qaimə), contract or payment details.
- 2 Enter the 10 digits above. The checker confirms the length and that the last digit is 1 or 2.
- 3 Check the last digit fits the supplier: 1 for a company or other legal person, 2 for an individual such as a sole entrepreneur.

Frequently Asked Questions
How many digits does a VÖEN have?
Ten: two for the territorial unit, six for the serial number, one check digit and one for the taxpayer type.
What does the last digit of a VÖEN mean?
It shows the taxpayer type: 1 for a legal person (such as a company or public body) and 2 for a natural person, including sole entrepreneurs. Any other final digit is a mistake.
Is the VÖEN the same as the Azerbaijan VAT number?
Yes. VAT payers are entered in the VAT register under their VÖEN, and there is no separate VAT number. Not every VÖEN holder is a VAT payer, though, so VAT status is a separate check.
Is there a published VÖEN check-digit formula?
No. The State Tax Service says the ninth digit is calculated by a “special algorithm” and has not published it.
Where must the VÖEN be shown?
On invoices, contracts, receipts and letters, and on customs, bank and payment documents. Payment and customs documents without it are refused.
Do foreign companies get a VÖEN?
Their branches and permanent establishments do: these are registered separately with the State Tax Service and receive their own VÖEN.
