Steps to validate an IBAN
There are two different validations that can be performed to ensure an UK IBAN is correct.
- 01First validation is done using the IBAN's Check Digits using the MOD97 algorithm.
- 02Second layer of validation can be carried out on the domestic sort code and account number combination
- 03Match the sort code against our Bank and Branch code directory to check if it exists
Found the correct IBAN, What to do next
With a Slovenian IBAN to hand, complete these checks before transferring.
- 01Confirm the registered beneficiary name with the Slovenian bank.

- 04For consumer P2P, Flik is the popular Slovenian instant payment scheme using a phone number or email, layered on top of BIPS and SCT Inst.
- 05Confirm the account holds EUR and send a small test for first-time corporate beneficiaries.

IBAN Rules in Slovenia
- 01IBAN is mandatory in Slovenia for every domestic and cross-border payment. Banka Slovenije assigns the bank identifier portion of the IBAN.
- 02The 19-character Slovenian IBAN begins with SI, two check digits, a 2-digit bank code, a 3-digit branch or account holder code, an 8-digit account number, and two national check digits.
- 03There is no parallel legacy domestic format in significant use. Slovenia adopted the euro in 2007 and is a full SEPA member. The same Slovenian IBAN handles every domestic payment, every SEPA destination, and inbound SWIFT wires. SCT Inst has been active in Slovenia since November 2020 and is mandatory for adhering banks via TIPS since November 2021.
