- Country code: two letters, e.g. CH for Switzerland or FR for France.
- Check digits: two digits that validate the IBAN and catch typing errors.
- Bank code: identifies the account-holding bank.
- Branch code: in some countries, identifies the branch.
- Account number: the individual account.
Length: fixed per country: 21 characters in Switzerland, 22 in the UK, 27 in France.

An IBAN contains no information about the account holder's name or balance.
