Czech Republic IBAN Format
24-character IBAN · CZK Czech Koruna · SEPA zone
A Czech Republic IBAN is 24 characters long and always begins with the country code CZ, followed by two check digits. The next 4 characters are the Bank Code. The remaining 10 characters identify the individual account number. The Czech Republic IBAN uses the CZK (Czech Koruna) and is a <strong>SEPA member</strong>, meaning euro transfers from other SEPA countries are fast and low-cost.

Pattern validates length, country code, check digit positions, and field character types. Does not verify the MOD-97 checksum (use the validator above for full validation).
$iban = strtoupper(str_replace(' ', '', $input));
if (!preg_match('/^CZ\\d{2}\\d{4}\\d{6}\\d{10}$/', $iban)) {
// Invalid Czech Republic IBAN format
}const iban = input.replace(/\s+/g, '').toUpperCase();
const pattern = /^CZ\d{2}\d{4}\d{6}\d{10}$/;
if (!pattern.test(iban)) {
// Invalid Czech Republic IBAN format
}import re

How to Find Your Czech Republic IBAN
Czech Republic accounts are traditionally identified using: Bank Code (4n) + Account Prefix (6n, optional) + Account Number (10n). Traditional Czech format: prefix-account/bank-code.. Your IBAN encodes these same components in the standardised international format.

Sending Money to Czech Republic
- Recipient's full name
- IBAN (24 characters, starts with CZ)
Czech Republic is a SEPA member but uses CZK (Czech Koruna), not the Euro. SEPA transfers in EUR are supported. The IBAN encodes the bank code, optional prefix, and account number. Domestic Czech accounts are often shown as "prefix-account/bank-code" (e.g., 19-2000145399/0800).
Specialist services typically charge significantly less than high-street banks for international transfers.
