About the Sao Tome and Principe IBAN
An IBAN (International Bank Account Number) for Sao Tome and Principe has 25 characters: the country code ST, a 2-digit check number, a 4-character bank code, a 4-character branch code and the account number. The check digits are calculated with the ISO 7064 MOD-97 algorithm, so a single typo makes the IBAN invalid — which is what this tool checks.
