The SEPA direct debit system was implemented in 2014 and has since then been used for electronic transactions within the EU. In addition to the 28 EU states, Norway, Switzerland, Iceland, Liechtenstein, Monaco and San Marino also support the SEPA Direct Debit Scheme.
Before SEPA, each EU member state had its own payment and transfer system. Under this scheme, anyone who wished to make a cross-border payment was not able to do so as seamlessly as they can now.
The IBAN is the most important aspect of SEPA direct debit. This is your International Bank Account Number and is the account number belonging to account holders in nearly every SEPA member state.
You also have a BIC (Bank Identifier Code), which is designed to make bank identification easier.
When collecting a SEPA payment, you will also need a direct debit mandate or company direct debit mandate.
