Whitehall 1212 was the famous telephone number of Scotland Yard. It was introduced in 1934 and was used by the public to contact the London Metropolitan Police information room for both emergency and non-emergency business. With the introduction of the 999 number for emergencies in 1937, Whitehall 1212 (dialled as WHI 1212) remained in use for non-emergencies until the 1960s and the introduction of all-figure numbering. Today the switchboard number for New Scotland Yard is 020 7230 1212, and the last four digits of the telephone number for several other Metropolitan police buildings are 1212.
