Check, understand and calculate IBANs

iban24 provides straightforward tools for checking an existing IBAN, calculating an IBAN from domestic account details, and creating EPC QR codes for euro transfers. They help identify typing mistakes, explain the information encoded in an IBAN and prepare payment details without registration.

Which tools are available?

The IBAN checker validates the length, structure and checksum of IBANs from all twelve supported countries. It extracts the bank identifier and account number and, when data is available, displays the bank name and BIC.

The IBAN calculator creates an IBAN from an account number and Bank code. Country-specific rules are applied automatically, and the identified bank can be reviewed before copying the result.

The SEPA QR code generator packages beneficiary, IBAN, amount and remittance details into an EPC-compliant QR code that compatible banking apps can scan.

What is an IBAN?

IBAN stands for International Bank Account Number. It is a standardised account identifier used to make bank details consistent and machine-readable across participating countries.

A Slovak IBAN starts with SK and contains a four-digit bank code, optional account prefix and account number. The example SK31 1200 0000 1987 4263 7541 illustrates the regional format.

The first two letters identify the country, followed by a two-digit checksum and the country-specific bank and account information. Length and internal structure vary between countries.

What does an IBAN check prove?

A valid checksum shows that the IBAN is structurally plausible and helps detect many common typing errors. Available bank data can also associate the encoded bank identifier with an institution.

It does not prove that an account is active, that a payment is safe or that the stated beneficiary owns the account. The account holderโ€™s name is not contained in an IBAN. Confirm important or unfamiliar payment details through a separate trusted channel.

Privacy and responsible use

Inputs are processed for the requested calculation, check or QR code and are not stored permanently. Use only bank information you are authorised to process and compare results with official information from the relevant bank before relying on them.

Frequently asked questions

How long is a Slovak IBAN? +

The field has six positions and is left-padded with zeros.
Where does the Slovak bank data come from? +

Can iban24 tell me who owns an account? +
No. An account holderโ€™s name is not encoded in the IBAN and cannot be retrieved by an IBAN checker.
Does a valid IBAN mean a payment is safe? +
No. It only means the IBAN is structurally valid. The beneficiary and purpose of a payment must be verified separately.
Why is the checksum important? +
The checksum helps detect common typing mistakes. If digits are missing, incorrect or transposed, it will often no longer match the rest of the IBAN.
Can I enter an IBAN with spaces? +
Yes. Spaces used for readability are removed before the IBAN is checked.
Is iban24 a bank? +
