Czechia — SEPA and IBAN Guide

Note: It is an EU member but does not use the euro (Czech koruna). The exchange-rate margin comes to the fore in euro transactions.

Czechia and SEPA: general status

Czechia is within the SEPA geographical scope but its official currency is not the euro. This distinction matters in practice: when sending or receiving euros from an account in Czechia, a currency conversion between the local currency and the euro is needed. In that case the real cost is often not the transfer fee but the exchange-rate margin the bank applies. Being within SEPA scope standardises the transaction but does not remove the need for currency conversion.

Czech IBANs are 24 characters.

In euro transactions the exchange-rate margin on the CZK–EUR conversion determines the total cost.

To measure the exchange-rate margin and compare alternatives you can use the exchange-rate margin tool.

Czechia IBAN structure

Czechia IBANs are 24 characters long. The structure consists of the following parts: the first 2 characters are the country code (CZ), the next 2 characters are the check digits (calculated with the MOD-97 algorithm) and the remaining 20 characters are the country-specific national part (BBAN) — containing fields such as the bank code, branch code and account number. You can check the structural validity of a CZ IBAN with the IBAN validation tool. Remember: a mathematically valid IBAN does not prove that the account actually exists or is active.

Sending and receiving euros with Czechia

Although Czechia is within SEPA scope, because it does not use the euro, the main cost item of sending/receiving euros here is often the exchange-rate margin. To measure the exchange-rate margin and compare alternatives, use the bank exchange-rate margin and euro currency-cost tools. If you make regular euro transactions, a euro account can reduce the recurring conversion cost.

To see whether a transfer will actually be SEPA or SWIFT, the estimated total cost and the amount that will reach the recipient, you can use the SEPA Route & Real Cost Calculator. The results are for information only and must be verified with the relevant bank before giving a payment instruction.

Institutions registered in the SEPA schemes in Czechia

According to the European Payments Council (EPC) official participant register, 16 payment institutions (banks/PSPs) in Czechia are registered in at least one SEPA scheme (data version: 2026-06-12). Scheme breakdown:

Important: being registered in a scheme does not mean the institution offers the service to all its customers (scheme participation ≠ customer availability ≠ operational status). You can search all participants by name or BIC in the EPC Participant Lookup tool.

Summary

Czechia is within the SEPA geographical scope and does not use the euro. For this reason, in euro transactions the currency conversion and the exchange-rate margin can be the decisive item of the total cost. The exact fees, limits and operational conditions vary by bank; uncertain information is marked as "Not verified" on this site.
