Classification of route numbers In Victorian times, people who took the bus would recognise the owner and the route of an only by its livery and its line name, with painted signs on the sides showing the two termini to indicate the route. Then, in 1906, George Samuel Dicks of the London Motor Omnibus Company decided that, as the line name 'Vanguard' had proved to be very popular, he would name all lines 'Vanguard' and number the company's five routes 1 to 5. Other operators soon saw the advantage, in that a unique route number was easier for the travelling public to remember, and so the practice of using route numbers soon spread.Charles Klapper (1984) The Golden Age of Buses . Page 64. Routledge, London , .

Historic classification Bus routes run by London Transport were grouped as follows:

The London Traffic Act 1924 imposed numbering known as the Bassom Scheme, named after Superintendent (later Chief Constable) Arthur Ernest Bassom of the Metropolitan Police who devised it. For many decades, variant and short workings used letter suffixes (e.g. "77B"). The numbers reflected the company that operated the route.

The numbering was revised in 1934 after London Transport was formed:

+From 1934NumbersType of service1–199"Central Area" red double-decker routes.200–289"Central Area" red single-decker routes.290–299"Central Area" night buses.300–399"Country Area" north of the River Thames. (Operated by London CountryBus Services after 1970)400–499"Country Area" south of the River Thames.500–699Trolleybuses.701–799Green Line Coaches.800–899"Country Area" "New Towns" routes.(LCBS after 1970)
