Post Office Savings Bank

Post Office Savings Bank is a name used by postal savings systems in several countries, including:
 * New Zealand, later renamed the PostBank
 * United Kingdom, later renamed the National Savings and Investments
 * Singapore, later renamed POSB Bank
 * Kenya, also known as the Kenya Post Office Savings Bank

Note that some of these institutions are no longer affiliated with a postal service, often as a result of privatization.
