Belarus UNP Checker
Check a Belarusian UNP (учётный номер плательщика) against the Ministry of Taxes and Duties’ State Register of Payers and see its status, with the name after sign-up.
What is a Belarusian UNP?
The UNP (учётный номер плательщика, payer’s account number) is Belarus’s single taxpayer number, used for every tax and duty, including VAT. The tax authority assigns it when a payer registers, and records it in the Ministry of Taxes and Duties’ State Register of Payers. A company’s UNP has 9 digits — for example 800013732 for MTS Belarus.
Belarusian UNP format
Region digit, serial number and a check digit — 9 digits.
(1 = Minsk City)
number
(mod 11)
Example: 100582333 (the Ministry of Taxes and Duties itself, as printed on its own website).
- Input: Nine digits, with or without spaces or an “УНП” label.
- Check digit: Weights 29, 23, 19, 17, 13, 7, 5, 3 on the first eight digits, modulo 11.
- Status: A found UNP shows its register status in Russian. Liquidated payers (“Ликвидирован”) are still found, so read the status, not just the result.
- Individuals: Letter-form UNPs of private individuals can’t be checked here; the checker reports them as an invalid format even though the form is legal.
How to check a Belarusian UNP
- 1 Find the UNP on the supplier’s invoice, contract or website, usually after the label “УНП”.
- 2 Enter the 9 digits above. The checker tests the check digit and looks the UNP up in the State Register of Payers.
- 3 Check that the status is “Действующий” (active) and that the name (shown in full after sign-up) matches your supplier.

Frequently Asked Questions
How many digits does a UNP have?
Nine characters. A company’s UNP is nine digits. Some UNPs issued to individuals start with two letters instead; our checker can’t check those.
What does the first digit of a UNP mean?
For most companies it shows the region whose tax inspectorate first issued the number: 1 Minsk City, 2 Brest, 3 Vitebsk, 4 Gomel, 5 Grodno, 6 Minsk region, 7 Mogilev. The UNP does not change when a company moves, and some numbers, such as MTS’s 800013732, start with 8.
Is the UNP the same as the Belarus VAT number?
Yes. The UNP is a single number used across Belarus for all taxes and duties, including VAT. Belarus issues no separate VAT number, and it is not in the EU’s VIES system.
Does a UNP found in the register mean the company is active?
No. A liquidated company still appears in the register under its UNP, with the status “Ликвидирован” (liquidated), and our checker still reports it as found. An active payer shows “Действующий”. Always read the status.
How is the UNP check digit calculated?
Multiply the first eight digits by 29, 23, 19, 17, 13, 7, 5 and 3, add the products and take the remainder after dividing by 11; that remainder is the ninth digit, and a remainder of 10 is never issued. The method was published by the Ministry of Taxes and Duties in a 2003 instruction; the current 2026 instruction does not restate it.
Can a company’s UNP change?
Not when its address changes. A company keeps its UNP when it is converted into another legal form or absorbs another company; a merger or division creates new UNPs.
