Posting a letter in Regency England was not as simple as walking down to the local post office and dropping off a stamped letter. Prior to January 10, 1840, stamps did not exist. Inked hand stamps applied to the letter indicated such information as whether it had been sent POSTPAID, UNPAID, PAID AT (city), PENNY POST, TOOLATE, 1dDUE or FREE, or what post office had collected the letter and what mileage it would cover. The 'letter box' itself only came into use after 1794, and did not become compulsory until after 1811. (The box consisted of a slit in the wall of the receiving house, which opened into a locked box. Private boxes could be hired in some towns for as little as 1/2d per letter to 4d per letter.)
On Monday August 2, 1784, the Post began to change when John Palmer's first Mail Coach left the Rummer Tavern in Bristol at four o'clock PM, carrying the mail and four passengers (which later became seven passenger, with four inside). Palmer had long advocated postal reform and expansion. Increases in commerce, industry and population demanded it. After his friend William Pitt became Prime Minister, Palmer got authority to try his reform ideas.
London had had its own General Post with local delivery since 1635 when Charles I opened the Royal Mail. In 1680, William Dockwra began his private Penny Post, named for the penny charge to mail any letter up to a pound. Two years later, the government took over and continued operation of the Penny Post. It comprised the cities of London and Westminster and the Borough of Southwark, covering letters received and delivered within ten miles, while the General Post serviced both London and the country side.
Since the post office's beginning, its revenues went to the crown, which held the right to grant the privilege of signing a letter and having it posted for free. This practice, known as franking, extended to both Houses of Parliament and certain officials.
