OK, so we’re not absolutely certain which street is the oldest in London to have introduced a number system. But one contender – according to The Postal Museum at least – is Prescot Street in Whitechapel.
That comes from a mention, in 1708, when topographer Edward Hatton made a special note of the street’s use of numbers instead of signs in his New View of London, in a rather clear indication that the use of numbers was still at that stage rather unusual.
The following century saw the numbering of properties become more common. Some suggest that the banning of hanging signboards (under an 1762 Act of Parliament) and the subsequent requirement that names to be fixed to all thoroughfares (under the Postage Act of 1765) both played a significant role in encouraging the use of house numbers.
Interestingly, not all numbering schemes are the same. The first schemes introduced in London involved numbering houses consecutively along one side of the street – this can still be seen in streets like Pall Mall and Downing Street, where Number 10 – official residence of the Prime Minister, is located next to number 11 – official residence of the Chancellor of the Exchequer.
The system used in more modern times, typically, involves numbering one side of the road with odd numbers (usually the left with the lowest number closest to the city or town centre) and the other with even.
But it’s fair to say that the numbering of houses was, initially at least, rather haphazard and it wasn’t until the passing of the Metropolitan Management Act that the numbering of properties become more standardised with the then new Board of Works given the power to regulate street numbers.
