SEPA Instant payment is executed only if the sender and receiver banks are connected to the SEPA Instant scheme.
You can check if your bank supports SEPA Instant here: https://www.iban.com/
Copy your IBAN into the search bar. You will see if SEPA instant is supported under “SCT-INST”.
If your bank supported SEPA Instant transfers – it will be sent/ received via SEPA Instant automatically.
If your bank does not support SEPA Instant transfers, even though Nuvei Accounts supports it – the transfer will be sent/ received via regular SEPA.
