How long is an IBAN from Russia?

33 characters, written in groups of four on paper (RU32 1234 5678 9012 3456 7890 1234 5678 9 as a synthetic example).

Can I find the bank from the IBAN?

The bank identifier is the 9 characters at positions 5–13; the bank’s name and BIC are in SWIFT’s licensed directory, which the API does not resolve.

Does a valid IBAN mean the account exists?

No. The check digits and the structure say the IBAN is well formed; existence and ownership are known to the bank only, at payment time.

Structure

Position	Length	Characters	Meaning
1–2	2	letters	country code RU
3–4	2	digits	check digits (ISO 7064 mod 97-10)
5–13	9	digits	bank code
14–18	5	digits	branch code
19–33	15	alphanumeric characters	account number

Example

RU32 1234 5678 9012 3456 7890 1234 5678 9 is a synthetic example: placeholder characters in every part, with the check digits computed so that the mod-97 test passes. It is not a real account and no bank issued it; use it to test an input field, not to pay.

SEPA

Russia is outside the SEPA schemes: a transfer to this IBAN goes through correspondent banks, with fees on both sides and several days of delay. A payout system should warn before paying.

Check one

The API checks the characters, the country, the length (33), the mod-97 check digits and the BBAN pattern, and returns the bank and branch identifier.
