IBAN stands for International Bank Account Number. Its length and structure has been internationally agreed, and revised several times since its launch in the 1990s. It contains up to 34 combined characters and digits. The IBAN always starts with a country or IBAN code such GB for the United Kingdom or NO for Norway. The IBAN consists of your Bank’s Sort Code, as well as your Account number. It can also contain additional information such as a Branch code or routing information. The IBAN was initially developed for use within the European Union, but it has expanded further afield, and as of 2020, 77 different countries use the IBAN.
The length of an IBAN varies from country to country. Not all countries use IBAN – for example India, which instead uses IFSC (Indian Financial System Code). If you want to check an existing IBAN or want to find out more about IBAN in general, please visit the official site.
