Regulation (NAP) – International Bank Account Number (IBAN)
The Central Bank of São Tomé and Príncipe establishes the International Bank Account Number (IBAN) as a mandatory 25-digit alphanumeric standard for cross-border payment operations, replacing the previous NAP 15/2015 regulation. The IBAN structure integrates a country code (ST), control digits (68), and the existing Bank Identification Number (NIB) to ensure secure account identification. This regulation defines precise electronic and paper formats, assigns specific bank identifiers for local financial institutions, and mandates compliance through the Central Bank's Information Technology Directorate.
