Kazakhstan BIN Check Digit Validator
Check that a Kazakh BIN (бизнес-идентификационный номер) has 12 digits and a correct check digit.
What is a Kazakh BIN?
The BIN (бизнес-идентификационный номер) is the 12-digit identification number of every legal entity, branch and representative office in Kazakhstan, and it is also the number the company is registered under for tax and, if it is a VAT payer, VAT. It starts with the year and month of registration and ends with a check digit — for example 980540002879 for Kcell JSC.

Example: 980540002879 (Kcell JSC, as printed on its own website and listed in the public procurement supplier register).
- Check digit: Two-pass modulo 11, the method published for the IIN.
- BIN or IIN: A fifth digit of 0–3 means the number is not a BIN: it is usually an IIN (a person) or an old RNN.
- Old RNN: The 12-digit RNN tax number was replaced by the BIN and IIN on 1 January 2013, and usually fails the check digit.
- Format check only: This checker tests the length and check digit. It does not query a Kazakh register, so it cannot confirm that a company exists or is active.
How to check a Kazakh BIN
- 1 Find the BIN on the supplier’s invoice, contract or website, usually labelled “БИН”.
- 2 Enter the 12 digits above. The checker tests the check digit.
- 3 Check the fifth digit: 4, 5 or 6 for a business. A failed check digit usually means a typo or an old RNN.

Frequently Asked Questions
What is a BIN in Kazakhstan?
The business identification number (бизнес-идентификационный номер): a 12-digit number formed for every legal entity, branch and representative office, and for individual entrepreneurs in joint entrepreneurship (совместное предпринимательство).
What do the BIN digits mean?
Digits 1–4 are the year and month of registration; digit 5 is the type (4 resident legal entity, 5 non-resident, 6 joint individual entrepreneurship); digit 6 the sub-type (0 head office, 1 branch, 2 representative office, 4 joint peasant farm); digits 7–11 a serial number; and digit 12 a check digit.
What is the difference between a BIN and an IIN?
The IIN (individual identification number) identifies a person, including a sole proprietor; the BIN identifies an entity. A BIN’s fifth digit is never 0 to 3, so the two cannot be confused. An IIN is personal data, so this page uses company examples only.
Does a sole proprietor have a BIN?
No. A sole proprietor is registered under their IIN. Only individual entrepreneurs in joint entrepreneurship receive a BIN.
Is the BIN the VAT number?
Kazakhstan has no separate VAT number. VAT payers are registered in the tax authority’s taxpayer database under their BIN (or, for an individual entrepreneur, their IIN).
How is the check digit calculated?
With the two-pass modulo-11 method published for the IIN (Interior Ministry Order 521 of 2023): weight the first 11 digits 1 to 11 and take the remainder after dividing by 11; if it is 10, repeat with weights 3 to 11, 1, 2, which the order prints. The BIN rules do not print a formula, but every live BIN we tested follows it.
