Post Office Limited, commonly known as the Post Office, is a retail post office company in the United Kingdom that provides a wide range of postal and non-postal related products including postage stamps, banking, insurance, bureau de change and identity verification services to the public through its nationwide network of around 11,500 post office branches. Most of these branch post offices (c. 99%) are run by franchise partners or by independent business people known as subpostmasters; Post Office Limited directly manages the remaining 1%, known as Crown post offices.
Since 2020, a public enquiry has been under way into the company's actions which led to between 700 and 900 subpostmasters being wrongfully prosecuted for financial crimes, in what has been described by the Criminal Cases Review Commission as "the biggest single series of wrongful convictions in British legal history".
