How do I know a Sao Tome and Principe IBAN is correct?
Check the length (25), that it starts with ST, and the mod-97 check digits. Our free IBAN checker does all three in one step and shows the bank when it is known.
Is Sao Tome and Principe in SEPA?
No. Sao Tome and Principe is not in the SEPA scheme, so transfers usually go as international (SWIFT) payments; the IBAN is still used.
Does a valid IBAN mean the account exists?
No. The check proves the number is well formed and the check digits match. Only the bank can confirm that the account is open and whose it is.
